updated May 15, 2023

Security misconfigurations are a common and significant cybersecurity issue that can leave businesses vulnerable to data breaches. According to the latest data breach investigation report by IBM and the Ponemon Institute, the average cost of a breach has peaked at US$4.35 million. Many data breaches are caused by avoidable errors like security misconfiguration. By following the tips in this article, you could identify and address a security error that could save you millions of dollars in damages.

What is a Security Misconfiguration?

A security misconfiguration occurs when a system, application, or network device’s settings are not correctly configured, leaving it exposed to potential cyber threats. This could be due to default configurations left unchanged, unnecessary features enabled, or permissions set too broadly. Hackers often exploit these misconfigurations to gain unauthorized access to sensitive data, launch malware attacks, or carry out phishing attacks, among other malicious activities.

What Causes Security Misconfigurations?

Security misconfigurations can result from various factors, including human error, lack of awareness, and insufficient security measures. For instance, employees might configure systems without a thorough understanding of security best practices, security teams might overlook crucial security updates due to the growing complexity of cloud services and infrastructures.

Additionally, the rapid shift to remote work during the pandemic has increased the attack surface for cybercriminals, making it more challenging for security teams to manage and monitor potential vulnerabilities.

List of Common Types of Security Configurations Facilitating Data Breaches

Some common types of security misconfigurations include:

1. Default Settings

With the rise of cloud solutions such as Amazon Web Services (AWS) and Microsoft Azure, companies increasingly rely on these platforms to store and manage their data. However, using cloud services also introduces new security risks, such as the potential for misconfigured settings or unauthorized access.

A prominent example of insecure default software settings that could have facilitated a significant breach is the Microsoft Power Apps data leak incident of 2021. By default, Power Apps portal data feeds were set to be accessible to the public.

Unless developers specified for OData feeds to be set to private, virtually anyone could access the backend databases of applications built with Power Apps. UpGuard researchers located the exposure and notified Microsoft, who promptly addressed the leak. UpGuard’s detection helped Microsoft avoid a large-scale breach that could have potentially compromised 38 million records.

2. Unnecessary Features

Enabling features or services not required for a system’s operation can increase its attack surface, making it more vulnerable to threats. Some examples of unnecessary product features include remote administration tools, file-sharing services, and unused network ports. To mitigate data breach risks, organizations should conduct regular reviews of their systems and applications to identify and disable or remove features that are not necessary for their operations.

Additionally, organizations should practice the principle of least functionality, ensuring that systems are deployed with only the minimal set of features and services required for their specific use case.

3. Insecure Permissions

Overly permissive access controls can allow unauthorized users to access sensitive data or perform malicious actions. To address this issue, organizations should implement the principle of least privilege, granting users the minimum level of access necessary to perform their job functions. This can be achieved through proper role-based access control (RBAC) configurations and regular audits of user privileges. Additionally, organizations should ensure that sensitive data is appropriately encrypted both in transit and at rest, further reducing the risk of unauthorized access.

4. Outdated Software

Failing to apply security patches and updates can expose systems to known vulnerabilities. To protect against data breaches resulting from outdated software, organizations should have a robust patch management program in place. This includes regularly monitoring for available patches and updates, prioritizing their deployment based on the severity of the vulnerabilities being addressed, and verifying the successful installation of these patches.

Additionally, organizations should consider implementing automated patch management solutions and vulnerability scanning tools to streamline the patching process and minimize the risk of human error.

5. Insecure API Configurations

APIs that are not adequately secured can allow threat actors to access sensitive information or manipulate systems. API misconfigurations – like the one that led to T-Mobile’s 2023 data breach, are becoming more common. As more companies move their services to the cloud, securing these APIs and preventing the data leaks they facilitate is becoming a bigger challenge.

To mitigate the risks associated with insecure API configurations, organizations should implement strong authentication and authorization mechanisms, such as OAuth 2.0 or API keys, to ensure only authorized clients can access their APIs. Additionally, organizations should conduct regular security assessments and penetration testing to identify and remediate potential vulnerabilities in their API configurations.

Finally, adopting a secure software development lifecycle (SSDLC) and employing API security best practices, such as rate limiting and input validation, can help prevent data breaches stemming from insecure APIs.

How to Avoid Security Misconfigurations Impacting Your Data Breach Resilience

To protect against security misconfigurations, organizations should:

1. Implement a Comprehensive Security Policy

Implement a cybersecurity policy covering all system and application configuration aspects, including guidelines for setting permissions, enabling features, and updating software.

2. Implement a Cyber Threat Awareness Program

An essential security measure that should accompany the remediation of security misconfigurations is employee threat awareness training. Of those who recently suffered cloud security breaches, 55% of respondents identified human error as the primary cause.

With your employees equipped to correctly respond to common cybercrime tactics that preceded data breaches, such as social engineering attacks and social media phishing attacks, your business could avoid a security incident should threat actors find and exploit an overlooked security misconfiguration.

Phishing attacks involve tricking individuals into revealing sensitive information that could be used to compromise an account or facilitate a data breach. During these attacks, threat actors target account login credentials, credit card numbers, and even phone numbers to exploit Multi-Factor authentication.

Learn the common ways MFA can be exploited >

Phishing attacks are becoming increasingly sophisticated, with cybercriminals using automation and other tools to target large numbers of individuals. 

Here’s an example of a phishing campaign where a hacker has built a fake login page to steal a customer’s banking credentials. As you can see, the fake login page looks almost identical to the actual page, and an unsuspecting eye will not notice anything suspicious.

Because this poor cybersecurity habit is common amongst the general population, phishing campaigns could involve fake login pages for social media websites, such as LinkedIn, popular websites like Amazon, and even SaaS products. Hackers implementing such tactics hope the same credentials are used for logging into banking websites.

Cyber threat awareness training is the best defense against phishing, the most common attack vector leading to data breaches and ransomware attacks.

Because small businesses often lack the resources and expertise of larger companies, they usually don’t have the budget for additional security programs like awareness training. This is why, according to a recent report, 61% of small and medium-sized businesses experienced at least one cyber attack in the past year, and 40% experienced eight or more attacks.

Luckily, with the help of ChatGPT, small businesses can implement an internal threat awareness program at a fraction of the cost. Industries at a heightened risk of suffering a data breach, such as healthcare, should especially prioritize awareness of the cyber threat landscape.

3. Use Multi-Factor Authentication

MFA and strong access management control to limit unauthorized access to sensitive systems and data.

Previously compromised passwords are often used to hack into accounts. MFA adds additional authentication protocols to the login process, making it difficult to compromise an account, even if hackers get their hands on a stolen password

4. Use Strong Access Management Controls

Identity and Access Management (IAM) systems ensure users only have access to the data and applications they need to do their jobs and that permissions are revoked when an employee leaves the company or changes roles.

The 2023 Thales Dara Threat Report found that 28% of respondents found IAM to be the most effective data security control preventing personal data compromise.

5. Keep All Software Patched and Updated

Keep all environments up-to-date by promptly applying patches and updates. Consider patching a “golden image” and deploying it across your environment. Perform regular scans and audits to identify potential security misconfigurations and missing patches.

An attack surface monitoring solution, such as UpGuard, can detect vulnerable software versions that have been impacted by zero-days and other known security flaws.

6. Deploy Security Tools

Security tools, such as intrusion detection and prevention systems (IDPS) and security information and event management (SIEM) solutions, to monitor and respond to potential threats.

It’s essential also to implement tools to defend against tactics often used to complement data breach attempts, for example. DDoS attacks – a type of attack where a server is flooded with fake traffic to force it offline, allowing hackers to exploit security misconfigurations during the chaos of excessive downtime.

Another important security tool is a data leak detection solution for discovering compromised account credentials published on the dark web. These credentials, if exploited, allow hackers to compress the data breach lifecycle, making these events harder to detect and intercept.

7. Implement a Zero-Trust Architecture

One of the main ways that companies can protect themselves from cloud-related security threats is by implementing a Zero Trust security architecture. This approach assumes all requests for access to resources are potentially malicious and, therefore, require additional verification before granting access.

Learn how to implement a Zero-Trust Architecture >

A Zero-Trust approach to security assumes that all users, devices, and networks are untrustworthy until proven otherwise.

8. Develop a Repeatable Hardening Process

Establish a process that can be easily replicated to ensure consistent, secure configurations across production, development, and QA environments. Use different passwords for each environment and automate the process for efficient deployment. Be sure to address IoT devices in the hardening process. 

These devices tend to be secured with their default factory passwords, making them highly vulnerable to DDoS attacks.

9. Implement a Secure Application Architecture

Design your application architecture to obfuscate general access to sensitive resources using the principle of network segmentation.

Learn more about network segmentation >

Cloud infrastructure has become a significant cybersecurity issue in the last decade. Barely a month goes by without a major security breach at a cloud service provider or a large corporation using cloud services.

10. Maintain a Structured Development Cycle

Facilitate security testing during development by adhering to a well-organized development process. Following cybersecurity best practices this early in the development process sets the foundation for a resilient security posture that will protect your data even as your company scales.

Implement a secure software development lifecycle (SSDLC) that incorporates security checkpoints at each stage of development, including requirements gathering, design, implementation, testing, and deployment. Additionally, train your development team in secure coding practices and encourage a culture of security awareness to help identify and remediate potential vulnerabilities before they make their way into production environments.

11. Review Custom Code

If using custom code, employ a static code security scanner before integrating it into the production environment. These scanners can automatically analyze code for potential vulnerabilities and compliance issues, reducing the risk of security misconfigurations.

Additionally, have security professionals conduct manual reviews and dynamic testing to identify issues that may not be detected by automated tools. This combination of automated and manual testing ensures that custom code is thoroughly vetted for security risks before deployment.

12. Utilize a Minimal Platform

Remove unused features, insecure frameworks, and unnecessary documentation, samples, or components from your platform. Adopt a “lean” approach to your software stack by only including components that are essential for your application’s functionality.

This reduces the attack surface and minimizes the chances of security misconfigurations. Furthermore, keep an inventory of all components and their associated security risks to better manage and mitigate potential vulnerabilities.

13. Review Cloud Storage Permissions

Regularly examine permissions for cloud storage, such as S3 buckets, and incorporate security configuration updates and reviews into your patch management process. This process should be a standard inclusion across all cloud security measures. Ensure that access controls are properly configured to follow the principle of least privilege, and encrypt sensitive data both in transit and at rest.

Implement monitoring and alerting mechanisms to detect unauthorized access or changes to your cloud storage configurations. By regularly reviewing and updating your cloud storage permissions, you can proactively identify and address potential security misconfigurations, thereby enhancing your organization’s data breach resilience.

How UpGuard Can Help

UpGuard’s IP monitoring feature monitors all IP addresses associated with your attack surface for security issues, misconfigurations, and vulnerabilities. UpGuard’s attack surface monitoring solution can also identify common misconfigurations and security issues shared across your organization and its subsidiaries, including the exposure of WordPress user names, vulnerable server versions, and a range of attack vectors facilitating first and third data breaches.

Cybersecurity and Social Responsibility: Ethical Considerations

Kyle Chin
updated Aug 21, 2023

Cybersecurity is necessary to protect data from criminals. However, the world of cybersecurity is not so simple. Therefore, a discussion of cybersecurity ethics needs to examine the morality of businesses collecting, processing, using, and storing data.

How cybersecurity professionals affect security measures is also worth exploring. Businesses and individuals should ask themselves whether the ends justify the means and to what extent they are willing to sacrifice data privacy for data protection.

This post underlines the ethical concerns and cybersecurity issues surrounding information security policies, procedures, systems, and teams and how they ought to contribute to the well-being of consumers.

What Are Ethics in Cybersecurity?

Ethics can be described as ideals and values that determine how people live and, increasingly, how businesses and their employees work.

While it is far from the technical specifications of networks and device configurations, it is an increasingly important part of business operations. It can be codified and included in an organization’s framework, determining acceptable behavior throughout the company in any scenario.

One of the main benefits of a strong ethical foundation for a business is that it will have a moral compass to help make ethical decisions in a rapidly changing business environment. The world is experiencing massive changes in information technology with advancements in artificial intelligence, machine learning algorithms, 5G, and data collection and processing.

The cyber threat landscape is also rapidly evolving, and businesses must make critical decisions about protecting themselves and their clients. With cybercrime on the rise and emerging threats driven by new technology such as AI, businesses need to elevate their cybersecurity. Doing so without sacrificing the customers or clients they set out to protect requires a strong ethical foundation and a written code of conduct.

The ACM Code of Ethics and Professional Conduct

In 1992, the Association for Computing Machinery (ACM) developed its Code of Ethics and Professional Conduct for computer systems workers. While it is not mandated, except for members of the ACM, it can be a useful starting point for Chief Information Security Officers (CISOs) and other stakeholders to think about and take a stance on ethical practices when tackling sensitive cybersecurity issues.

The Code of Ethics was revisited and revised in 2018. While the cloud stands to make more updates in the face of 5G, AI, and other advances in computing, it remains a valuable resource for anyone seeking to define ethical standards concerning computer systems and technology.

Having a clear set of ethical principles is helpful because it can clarify and speed up important decision-making in an increasingly complex, rapidly evolving cyber threat landscape.

The ACM Code of Ethics is divided into four categories:

  • General Ethical Principles
  • Professional Responsibilities
  • Professional Leadership Principles
  • Compliance with the Code

General Ethical Principles

The General Ethical Principles section makes the following assertions about the role of computing professionals. Computing professionals should:

  1. Use their skills to benefit society and people’s well-being, and note that everyone is a stakeholder in computing.
  2. Avoid negative and unjust consequences, noting that well-intended actions can result in harm that they should then mitigate.
  3. Fully disclose all pertinent computing issues and not misrepresent data while being transparent about their capabilities to perform necessary tasks.
  4. Demonstrate respect and tolerance for all people.
  5. Credit the creators of the resources they use.
  6. Respect privacy, using best cybersecurity practices, including data limitation.
  7. Honor confidentiality, including trade secrets, business strategies, and client data.

Professional Responsibilities

The Professional Responsibilities section also says that computing professionals must prioritize high-quality services, maintain competence and ethical practice, promote computing awareness, and perform their duties within authorized boundaries.

  1. Strive to achieve high quality in both the processes and products of professional work.
  2. Maintain high standards of professional competence, conduct, and ethical practice.
  3. Know and respect existing rules pertaining to professional work.
  4. Accept and provide an appropriate professional review.
  5. Give comprehensive and thorough evaluations of computer systems and their impacts, including analysis of possible risks.
  6. Perform work only in areas of competence.
  7. Foster public awareness and understanding of computing, related technologies, and their consequences.
  8. Access computing and communication resources only when authorized or when compelled by the public good.
  9. Design and implement systems that are robustly and usably secure.

Professional Leadership Principles

Professional Leadership pertains to any position within an organization that has influence or managerial responsibilities over other members and has increased responsibilities to uphold certain values set by the organization.

  1. Ensure that the public good is the central concern during all professional computing work.
  2. Articulate, encourage acceptance of, and evaluate fulfillment of social responsibilities by the organization or group members.
  3. Manage personnel and resources to enhance the quality of working life.
  4. Articulate, apply, and support policies and processes that reflect the principles of the Code.
  5. Create opportunities for members of the organization or group to grow as professionals.
  6. Use care when modifying or retiring systems.
  7. Recognize and take special care of systems that become integrated into the infrastructure of society.

Compliance with the Code

Of course, compliance with the Code of Ethics is the only way to ensure cybersecurity professionals uphold certain ethical standards. Without enforcement of the Code of Ethics or similar ethical considerations, it is impossible to document and recognize adherence to ethics and social responsibility.

  1. Uphold, promote, and respect the principles of the Code.
  2. Treat violations of the Code as inconsistent with membership in the ACM.

Corporate Social Responsibility and Cybersecurity

To compete with other businesses and delivery the user experiences that consumers expect, modern businesses are obligated to collect and process increasing amounts of data. This particular genie is already out of the bottle, so the question is not really whether big data should exist but how businesses use and protect data.

Cybersecurity helps prevent and mitigate data breaches and attacks that threaten information security, so it is crucial for public safety and well-being, as well as helping to ensure the longevity of businesses. There is so much at stake that cybersecurity professionals should be willing to come under scrutiny by those in and outside the field.

Cyber ethics encapsulates common courtesy, trust, and legal considerations. Acting ethically should protect individuals, organizations, and the wider economy. So it’s vital for cyber professionals and the organizations that employ them. The following considerations will explore what makes effective cybersecurity and explain how poor cybersecurity is not only ineffective but also potentially unethical.

Information Security

Businesses have a moral obligation to protect their customers and business partners. They benefit from data that allows them to operate and can give them a competitive advantage, but they need to protect that information from hackers and accidental leaks.

Unfortunately, businesses that are hacked are often at fault. While nobody deserves to be hacked, a business’s moral obligations to consumers are such that they are expected to have adequate cybersecurity for their computer systems and respond promptly and decisively in the event of a cyber incident.

Equifax’s 2017 cyber attack is a prime example of a business that damaged its reputation due to inadequate cybersecurity and poor response to attacks. It was hacked around May 2017 but did not disclose the breach until September.

While Equifax’s president for Europe said that protecting consumer and client data was always its top priority, it failed to follow through with patching a software security vulnerability it knew about in March and failed to let affected customers know so that they could take steps to protect themselves from phishing, identity theft, and other kinds of fraud.

Equifax’s human and technological failures compromised 14.5 million sensitive data records, including addresses, birth dates, driver’s licenses, and social security numbers. It also puts the firm’s morality into question, as it processes sensitive information and purports to help customers with their financial security, but its ineffective cybersecurity procedures put those people at risk.


Ethically, businesses should be prepared to disclose the risks inherent to the business if they could substantially affect people, whether customers, business partners, or their supply chain.

Data breach reporting is a significant part of a business’s transparency. While reporting a breach highlights a business in crisis, failing to report promptly can lead to a more significant loss of trust, criticism from industry professionals, and sometimes, as in Equifax’s case, action from investigators.

Even if a business operates in an unregulated industry or a cyber attack does not cause business disruption or affect clients, reporting all data breaches is a worthwhile ethical consideration. The more businesses report cyber attacks, the more information there is for cybersecurity experts and industry professionals to share and learn from. This protects other businesses and their clients from emerging threats.

While revealing a vulnerability or data breach according to applicable regulations may not be necessary, there is a moral question as to whether this information should be shared regardless. Being transparent about discovering vulnerabilities can help all businesses protect their information systems and clients.

Cyber incidents are varied, and cybercriminals are continually researching new methods to apply and vulnerabilities to exploit. So how businesses respond to threats and potential threats needs to change on a case-by-case basis. However, they can base their decision-making on an explicit, underlying ethical framework that guides the business according to its values and corporate social responsibility.

While some businesses reject revealing data breaches “unnecessarily” for fear of losing trust or business, disclosing data breaches late can cause more damage and even harsh penalties. Handling a crisis professionally and ethically can even be good for a firm’s reputation, as in the case of Norsk Hydro’s handling of the fallout from its 2017 ransomware attack, which impressed industry professionals and cybersecurity experts.

Organizations and their cybersecurity teams can reap rewards from being proactive and enacting policies and procedures according to a defined, documented code of ethics.

Security vs. Privacy Protection

A prime ethical dilemma in cybersecurity concerns cybersecurity experts’ privileged access to sensitive information. In effect, they must understand how cybercriminals operate and be able theoretically to perform the same feats without crossing the line into the territory of black hat hackers.

Cybersecurity professionals set access privileges, monitor network activity, and can read people’s emails. They can scan machines and therefore can compromise and protect people’s personal lives.

Collecting data leads to ethical questions but so does protecting it. Ethically, everyone deserves dignity, which is tied in with privacy. But how do businesses achieve privacy when they collect customer data, and that data must be protected?

Social engineering and identity theft are among the biggest cyber risks to the public. This is partly because it can affect people beyond those whose data is stored. With stolen data, a cybercriminal can launch phishing attacks against the victim and their associates.

Keeping personally identifiable information (PII) secure, therefore, is paramount. However, that requires personnel to access and in some ways manipulate that data. Anyone working in cybersecurity is walking a tightrope of ethical issues every day. It’s helpful to acknowledge this so that grey areas can be defined and clients are reassured.


Excellent cybersecurity is not just about technical standards. Cybersecurity professionals need to demonstrate their moral standards when handling sensitive data. During daily duties, cybersecurity professionals will have access to confidential data and files. This could include sensitive data such as payroll details, private emails, and medical records.

Intellectual property theft is one of the most costly cybercrime, as stealing a business’s product designs and concepts can give opponents an unfair advantage while saving them the massive cost and time investment of product development. Nation-states may sponsor cyber espionage to achieve this advantage, risking destabilizing the affected nation’s market and economy. Intellectual property theft can be a serious risk to human life in a critical infrastructure industry, such as defense or healthcare.

It almost goes without saying that cybersecurity staff shouldn’t say anything to the public about the confidential data and intellectual property they see, nor should they store or transmit it in any way that is not aligned with the business’s goals to protect data. “Almost” because ethical debates often involve bringing things out of the shadows and into the light.

An implicit understanding may not be enough to ensure the confidentiality of sensitive data. It’s better to have documented policies and procedures regarding confidentiality and the organization’s attitude to how cybersecurity interacts with personal data.

On April 13, 2023, federal investigators arrested Jake Teixeira, an air national guardsman, concerning the unauthorized transmission of classified US intelligence documents. Teixeira’s role in the Massachusetts Air National Guard was as a Cyber Transport Systems Journeyman responsible for maintaining communication networks.

While there are some claims that he acted as a whistleblower, he shared the documents in a small private group on a social media platform, not seeming to have intended to share it with a wider audience.

Nonetheless, this massive data security breach calls into question cybersecurity professionals’ commitment to upholding the law when faced with tempting confidential information. Cybersecurity teams must be continuously committed and engaged to perform their duties honorably, within the law, and according to the expectations of their employers.

Although The Association for Computing Machinery (ACM) developed a Code of Ethics and Professional Conduct for computer systems workers, ethics in cybersecurity is not regulated. Ethics can’t be ensured by law enforcement.

Having said that, unethical behavior can lead to fines, loss of revenue, and loss of customers, so businesses and cybersecurity professionals will benefit from addressing ethics seriously.

While there’s no handy accreditation that cybersecurity staff can achieve to attest to their honesty, hiring organizations should look at a cybersecurity firm’s history and culture for evidence of its ethical stance on cybersecurity.


Cybersecurity professionals cannot have a lapse of concentration or a couple of days where they’re off their game and let things slide. Responsibility for others’ information security is a massive contractual and ethical responsibility. Almost no matter what the individual does, scrutiny will be on any assigned cybersecurity team or professional in the event of a cyber incident.

Cybersecurity professionals must maintain their competence level, respect sensitive information privacy, and uphold the well-being of those they serve. It requires honesty for these team members to evaluate their skills, abilities, and alertness and ensure that they take the appropriate action to stay on top of their game.

Ethical Hacking

Ethical hacking refers to sanctioned hacking by businesses onto their own systems to discover vulnerabilities and security gaps. Ethical hackers attempt to find vulnerabilities to exploit and break into information systems to fix those issues before cybercriminals find them.

But now imagine an ethical break-in, in which an ethical burglar break into people’s homes and then advises them on which locks they should have used and where to hide their laptops. Ethical hackers use illegal means to achieve positive results.

To protect data from hackers, particularly when they are using increasingly sophisticated methods and rapidly advancing technologies, cybersecurity professionals must use the same techniques. Cybersecurity programmers need to know how to commit crimes by black hat hackers, such as stealing credit card data. What stops them from doing this, however, is that ethical principles separate them.

Cyber professionals must be aware of computer ethics since what they do gives them access to privileged information. This is especially true for professionals working in critical infrastructure, including defense, healthcare, finance, and manufacturing, where the consequences of unethical actions regarding sensitive data could cause serious harm to individuals, organizations, and the economy.

Cybersecurity professionals and businesses that need them must understand cyber ethics and insist that a moral code is always evident in their attitude and behavior.


Before the dark web became known as a haven for hackers and cybercriminals to extort money, purchase malware, and prepare to commit multiple kinds of cybercrime, it existed in large part to protect whistleblowers.

Whistleblowing refers to someone reporting their organization’s wrongdoing, typically an employee. A whistleblower’s objection might be that the organization or someone in it is acting illegally, fraudulently, immorally, or without proper regard for safety or human rights. Furthermore, the issue should be in the public interest.

Public sector whistleblowers are protected by the First Amendment. Even so, whistleblowing might be considered a grey area when considering cyber ethics.

If a cybersecurity expert reveals confidential information to stop a harmful practice, the objective is good, but how they achieved this breaks the ethical confidentiality essential to that employee-employer relationship.

Edward Snowden famously blew the whistle on the National Security Agency’s unethical, invasive surveillance of innocent US citizens. While the former computer intelligence consultant and CIA systems administrator is a hero to many, his actions were criminal. The US Department of Justice charged him with stealing government property and violating the Espionage Act of 1917.

Jesselyn Radack, from the Government Accountability Project, argued that Snowden’s contract with the Government was less important than the social contract of a democracy.

Security vs. Functionality

While organizations have a responsibility to society to protect data, they need to balance this requirement with maintaining functionality. A technically workable cybersecurity solution is not necessarily the best if it prevents the organization from operating. This is a moral debate because organizations won’t always use the most secure cybersecurity practices or systems. Operating a modern business means navigating such trade-offs daily.

Cybersecurity experts have a responsibility to balance securing information and keeping organizations running. Some businesses need to be able to work quickly, such as in healthcare where the most robust security system could slow daily operations and risk human life. A holistic approach to information security is required based on thorough risk management.

Exploring the ePrivacy Directive

Leah Sadoian
updated Sep 15, 2023

There are a variety of cybersecurity regulations in Europe, including the ePrivacy Directive, which focuses on enhancing data protection, processing personal data, and privacy in the digital age. This Directive, recently updated with the ePrivacy regulation, continues the European Union’s ongoing efforts to create cohesive and comprehensive European data protection and cybersecurity standards across all member states.

Upgrade your organization’s cybersecurity standards with UpGuard Breachsight >

What is the ePrivacy Directive?

The Privacy and Electronic Communications Directive 2002/58/EC, or the ePrivacy Directive, is a European Union cybersecurity directive on data protection and privacy protection. The current ePrivacy Directive addresses the growing landscape of new digital technologies and electronic communications services. The Directive aims to harmonize national protection of fundamental rights within the EU, including privacy, confidentiality, and free data movement.

The ePrivacy Directive was enacted in 2002. It required each EU Member State to pass its national data protection and privacy laws, regulating essential issues like consent, spam marketing, cookies, and confidentiality.

Key Components of the ePrivacy Directive

Since the ePrivacy Directive focuses on the protection of online privacy in the electronic communications sector, the Directive’s key components include standards around how people communicate with each other electronically, aligning them with recent technological advancements.

Cookies and Consent Mechanisms

A significant component of the ePrivacy Directive is cookies, which are small data files websites use to track user behavior. Specifically, the Directive states that websites must obtain informed user consent before storing or retrieving any information on their electronic devices, giving the ePrivacy Directive the nickname “cookie law.”

Gaining this consent includes providing end-users with information about the purpose of the data storage and an opportunity to accept or opt-out. Many websites utilize a cookie banner to obtain cookie consent for website visitors. However, cookies essential for site functionality or for delivering a service requested by a user (like tracking the items in an online shopping cart) are exempt from this requirement. Note that the Directive applies to both first-party and third-party cookies.

Protection of Personal Data in Communications

Concerning data protection, the Directive states that providers of electronic communication services must ensure that their services are secure—which in turn secures any personal data that may be shared through those services. Standard electronic communication services include email and instant messaging.

These providers must also inform their users whenever a risk, such as a data breach or ransomware attack, leaves their personal data vulnerable to misuse.

Data Retention

Data retention refers to how companies retain your data, and the ePrivacy Directive includes standards for this practice.

Specifically, the Directive states that when providers of services no longer need your data, they must erase or anonymize it. There are specific situations in which data retention is allowed, such as billing services or issues of national security.

Otherwise, data may only be retained if a user consents to it, and they must also be informed why the data is being processed and the length of time it will be stored.

Unsolicited Marketing Communications

The ePrivacy Directive includes strict restrictions on the use of digital marketing communications. Unsolicited communications for direct marketing purposes are not allowed without the recipient’s consent. This includes email and text message marketing.

Typically, this is done through opt-in or opt-out systems determined by individual EU member states. However, the overall rule is that marketing communications cannot be sent without explicit consent from the user.

Location Data

The ePrivacy Directive sets instructions for using location data obtained through electronic communications. Specifically, location data must be processed with informed consent and should be anonymized when no longer needed.

This provision is very relevant for mobile service providers and location-based services. Like the marketing communications provision, an opt-in or opt-out mechanism allows users to provide explicit consent before location data is provided.

Communications Confidentiality

Companies that provide electronic communication services must implement appropriate security measures to safeguard users’ data. They must also notify users and relevant authorities in case of any security breaches involving personal data. Additionally, the Directive governs how traffic data, which includes information about communication between individuals, can be processed and stored.

Even though the primary goal of the ePrivacy Directive is to protect confidentiality, it does allow for the retention of metadata for billing, service quality, and other purposes. Member states may require data retention under specific conditions, often related to national security or criminal investigations.

Member State Laws

The ePrivacy Directive is a directive that requires every EU Member State to establish national laws to accomplish the Directive’s goals. There is some variation in the regulations across different countries due to this, unlike the GDPR, which is a regulation and applies directly throughout the EU.

How the ePrivacy Directive Affects the GDPR

The General Data Protection Regulation (GDPR) is a mandatory regulation in Europe that protects the personal data of its citizens. Since the GDPR and the ePrivacy directive both concern data privacy, they work in tandem across various components.

  • Scope: The ePrivacy Directive focuses explicitly on the electronic communications sector, and the GDPR extends data privacy laws to other industries that process personal data.
  • Consent: Both the ePrivacy Directive and the GDPR focus on user consent, but the GDPR also outlines principles of lawful processing, including contractual necessity, legitimate interests, and legal obligation.
  • Confidentiality vs. Data Protection: The ePrivacy Directive is primarily concerned with the privacy and security of electronic communications, and the GDPR includes broader concepts of data protection like data minimization, accountability, and individuals’ rights to access, rectify, and erase personal data.
  • Security Measures: The ePrivacy Directive requires providers of electronic communication services to implement security measures to protect user information. At the same time, the GDPR mandates robust security measures and includes the concept of “data protection by design and default.”
  • Data Breach Notifications: Both require notification of data breaches to users and regulatory authorities. The ePrivacy Directive only requires communication service providers to provide notification, but the GDPR extends that requirement to all data controllers and processors.

Who Must Comply with the ePrivacy Directive?

The ePrivacy Directive applies to entities providing electronic communication services in the EU, including but not limited to:

  • Telecommunication Companies: Traditional telecom providers offer fixed or mobile telephony services.
  • Internet Service Providers (ISPs): Entities providing internet connectivity services.
  • Over-the-top (OTT) Providers: Companies that offer online communication services, such as instant messaging apps and VoIP services like Skype or WhatsApp.
  • Website Owners: Any website that uses cookies or similar technologies to track user behavior must comply with the Directive.
  • Email and SMS Marketers: Businesses that send marketing messages via email or SMS must adhere to the rules set by the Directive.
  • Location-Based Services: Services that use location data also fall under the Directive’s jurisdiction.

Penalties for Noncompliance

Penalties for failing to comply with the ePrivacy Directive may differ across EU Member States, as each country is responsible for incorporating the Directive into national law. As a result, penalties can vary from monetary fines to legal actions, and the severity of the consequences will depend on the nature of the breach and the location of the incident. Below are some typical types of penalties that may be enforced:

  • Financial Fines: These can vary widely from state to state but are generally designed to be dissuasive. Some countries have a cap on fines, while others may calculate them as a percentage of the annual turnover of the offending company.
  • Legal Sanctions: In some instances, severe or repeat violations may result in legal action, including the possibility of criminal charges.
  • Reputational Damage: Beyond legal penalties, companies that violate ePrivacy laws often suffer significant reputational damage, which can result in loss of customer trust and revenue.
  • Cease and Desist Orders: Regulatory bodies may require the violating entity to stop the offending action immediately, often at the cost of temporarily or permanently turning off a service or feature.
  • Data Audits: In some cases, the regulatory bodies may require a thorough audit of data protection practices within the offending organization.
  • Notification Requirements: Failing to notify the authorities and individuals affected by a data breach, as stipulated by the Directive, can lead to additional penalties.

In 2022, Google and Meta were both found to be in violation of the ePrivacy Directive and faced steep fines for their non-compliance. France’s Commission Nationale Informatique & Libertés (CNIL) fined Google €150M and Facebook another €60M for not offering an option for users to reject non-essential cookies in line with the option to accept all tracking. This violates the ePrivacy Directive’s requirements around cookies and consent mechanisms.

The Future: Introducing the ePrivacy Regulation

Since 2002, the digital communications industry has evolved rapidly, which means the ePrivacy Directive needed drastic updating. In 2017, The European Commission proposed the ePrivacy Regulation, which aims to replace the existing ePrivacy Directive and better align it with the General Data Protection Regulation (GDPR) data protection laws.

The regulation is still under discussion amongst the EU Council because of the scope of the rules and the impact it would have on big tech companies, large telecom providers, and even areas of online advertising, media, and national security.

This new legislation is a regulation of the European Parliament and Council of the European Union. It specifies and complements the ePrivacy Directive on privacy-related topics such as the confidentiality of communications, consumer privacy controls through electronic consent and browsers, and cookies.

Key Differences

  • Legal Form and Scope: As a directive, member states must achieve specific goals but have the authority to decide how to do so, which can lead to differences in implementation across countries. The ePrivacy Regulation is a directly applicable law that becomes enforceable across the European Union, creating greater consistency.
  • Cookies and Trackers: The ePrivacy Regulation expands on the requirement for user consent before utilizing cookies and tracking technologies but simplifies the rules around this requirement. This can include allowing users to consent through browser extensions and specific exceptions for cookies that improve user experience.
  • Consent: The ePrivacy Regulation aligns the ePrivacy Directive’s requirements for user consent with the GDPR’s more stringent standards. This also simplifies consent mechanisms.
  • Electronic Marketing: The ePrivacy Regulation extends the ePrivacy Directive’s restriction on unsolicited communications for marketing purposes to cover new marketing methods and forms of electronic communication, like marketing through social media platforms.
  • Data Protection and Security: The ePrivacy Directive requires service providers to utilize security measures and report data breaches. The ePrivacy Regulation aligns those requirements with the GDPR’s broader data protection framework, which has stricter data breach notification timelines.
  • Penalties: Instead of allowing individual member states to determine penalties for noncompliance, the ePrivacy Regulation adopts a penalty framework similar to the GDPR, with fines based on a company’s global turnover, up to 4% or up to €20 million, whichever is higher. It also gives more power to Data Protection Authorities, aligning it with the GDPR.
  • International Impact: The ePrivacy Regulation’s alignment with the GDPR means data protection standards are not just primarily focused on EU member states but now affect any company that offers services or data transfers to EU residents (even if they are not located within the EU).

What is ISO 31000? An Effective Risk Management Strategy

Edward Kost
updated Sep 14, 2023

ISO 31000 was specifically developed to help organizations effectively cope with unexpected events while managing risks. Besides mitigating operational risks, ISO 31000 supports increased resilience across all risk management categories, including the most complicated group to manage effectively – digital threats.

Whether you’re considering implementing ISO 31000 or you’re not very familiar with this framework, this post provides a comprehensive overview of the standard.

Learn how UpGuard simplifies Vendor Risk Management >

What is ISO 31000?

ISO 31000 is an international standard outlining a risk management structure supporting effective risk management strategies. The standard is divided into three sections:

  1. Principles
  2. Framework
  3. Process
The three components of ISO 31000 - Principles, Framework, Process


The objective of all of the principles of ISO 31000 is to simultaneously increase the value and protection aspects of a management system.

The 11 principles of ISO 31000 are as follows:

  • Risk management creates and protects value – Risk management should support objective achievement and performance improvements across various sectors, including human health and safety, cybersecurity, regulatory compliance, environmental protection, governance, and reputation.
  • Risk management is an integral part of all organizational processes – Risk management shouldn’t be separated from the main body of a management system. It should be integrated into an organization’s processes to create a risk-aware culture. Management teams should champion this cultural change.
  • Risk management is systematic, structured, and timely – Risk management should cover the complete scope of systemic risk. It shouldn’t be focused on a single business component prone to risks, like the sales cycle.
  • Risk management is tailored – A risk management program should be tailored to your objectives within the context of internal and external risk profiles.
  • Risk management is transparent and inclusive – All appropriate stakeholders and decision-makers should be involved in ensuring risk management remains relevant and updated.
  • Risk management is dynamic, iterative, and responsive to change – A risk management program shouldn’t be based on a rigid template. It should be dynamic, capable of conforming to changing internal and external threat landscapes.
  • Risk management is based on the best available information – Risk management processes shouldn’t be limited to historical data, stakeholders’ feedback, forecasts, and expert judgments. It’s essential to consider the limitation of data sources and the likely possibility of divergent opinions among experts.
  • Risk management is part of decision-making – Risk management should help leadership teams make intelligent risk mitigation decisions by understanding which risks should be prioritized to maximize impact.
  • Risk management takes human and cultural factors into account – All risk management activities should be assigned to individuals with the most relevant competencies. Appropriate tools should be available to these individuals to support their efforts as much as possible.
  • Risk management facilitates continual improvement of the organization – Strategies should be developed to ensure risk management efforts are continuously improving.
  • Risk management explicitly addresses uncertainty – Risk management should directly address uncertainty by understanding its nature and finding ways to mitigate it.


The framework component of the ISO 31000 standard outlines the structure of a risk management framework, but not in a prescriptive way. The objective is to help organizations integrate risk management into their overall management system based on their unique risk exposure context. Businesses should implement the framework through the lens of their risk management objectives, prioritizing the most relevant aspect of the proposed framework. This flexibility makes any management system capable of mapping to ISO 31000, making the standard industry agnostic.

ISO 31000 can be implemented by any industry to reduce enterprise risk, regardless of size or existing risk management process.

The driving factor for the framework aspect of ISO 31000 is the management team’s commitment to embedding a risk management culture across all organizational levels.

Leadership and commitment branching out into 5 points - integration, design, implementation, evaluation, and improvement.

The five framework pillars of ISO 31000 are as follows:

  • Integration – The risk management framework should be integrated into all business processes, a change that follows the management team’s push for a cultural shift towards greater risk awareness.
  • Design – The design of the final risk management framework must consider the organization’s unique risk exposure and risk appetite.
  • Implementation – An implementation strategy should consider potential roadblocks, resources, timeframes, key personnel, and mechanisms for tracking the framework’s efficacy following implementation.
  • Evaluation  The evaluation components broaden the focus on measuring framework efficacy. This process could involve appealing to various data sources, such as customer complaints, the number of unexpected risk-related events, etc.
  • Improvement – This is the final step of the popular management system design model, Plan Do, Check Act (PDCA). Improvements should be made based on the insights gathered in the evaluation phase. The objective of each improvement interaction is to reduce the number of surprises caused by the risk management framework.

The design of the risk framework should be based on business objectives and a risk management policy within an organization’s unique risk context (the contextualization of risks is a recurring theme in ISO 31000).

Risk management policy feeding program design which is part of a cycle consissting of - program design, implementation, monitoring, improvement.

The Framework stage sets the broad risk management context, which is then refined in the Process stage, setting the foundation for more meaningful insights gathered through risk assessments.


The process approach to ISO 31000 is represented graphically as follows:

Risk management process lifecycle.

Communication and Consultation

The first stage of this process approach is communication and consultation. The more cross-functional opinions that are heard, the more comprehensive your risk management efforts will be. This stage draws upon ISO 31000’s inclusivity and cultural factor principles.

Communications aren’t just limited to internal functions. External stakeholders should be involved in all decision-making processes. This will encourage stakeholder involvement in all stages of the risk management program’s development – which supports the primary objective of the Framework stage in ISO 31000:2018.

Scope, Context, and Criteria

Ideally, many of these mechanisms should already be established in your management system. The scope of all management activities is performed within the organization’s context, as defined in ISO 9001 Clause 4.1.

Contextual intelligence is a consideration of all internal and external issues impacting the achievement of business objectives. Contextualization can be achieved by gathering information from the following sources:

  • Risk assessment of internal and external risk factors
  • Internal audits
  • Organization policy statements
  • The use of a SWOT template (Strengths, Weaknesses, Opporitnies, Threats)
  • Strategy documents
  • Questionnaires (for internal and external process investigations)
  • Interviews (with stakeholders, senior management, cross-functional teams including finance, human resources, engineering, training, etc.).

Learn about UpGuard’s security questionnaires >

The criteria used to assess risk depends on the most appropriate initiative and objective methodology as outlined in the value creation principle of ISO 31000.

This could include

  • Strategic objectives
  • Operational objectives
  • Business objectives
  • Health and safety objectives
  • Cybersecurity objectives

Start by narrowing your focus to a single scope. Then, after the process has been proven to work, expand your scope into other regions.

Risk Assessment

After defining your scope, context, and criteria, the actual risk assessment process begins. There are three primary stages in the risk assessment lifecycle.

  • Risk Identification – Understanding the source of discovered risks and their classification (whether they originate from internal or external attack surfaces)
  • Risk Analysis – Understanding the impact of identified risks and potential risks and the efficacy of their associated security controls.
  • Risk Evaluation – A comparison of discovered risks against your risk register.
  • Deciding which risk should be addressed based on an acceptance criterion defined by your risk appetite.

Learn about UpGuard’s vendor risk assessment features >

Risk evaluation data will determine which actions need to take place. Any control adjustments or framework improvements will be relative to each unique scope, context, and criteria scenario.

Stakeholders should be involved in deciding how to best respond to risk evaluation insights.

Risk Treatment

The risk treatment stage is where you decide the best course of action. These decisions will depend on your risk appetite, which defines the threshold between the levels of risk that can be accepted and those that need to be addressed.

Different types of risk should be considered, including:

  • Strategic risks
  • Cybersecurity risks
  • Reputational risks
Security controls suppress cybersecurity inherent risks within acceptable risk appetite levels
Security controls suppress cybersecurity inherent risks within acceptable risk appetite levels

Your methodology for treating risks depends on the risk culture being developed by the management team. Some organizations have a very low-risk tolerance, while others (such as those in heavily regulatory industries like healthcare) have a very low tolerance to risk. These tolerance bands are decided during the calculation of your risk appeite. If your risk appetite has already been determined, revise it to ensure it’s clear enough to support the risk management standards of ISO 31000.

Learn how to calculate your risk appetite >

A risk matrix is helpful in the risk treatment phase as it indicates what risks should be prioritized in remediation efforts to minimize impact.

In the context of Vendor Risk Management, a risk matrix indicates which vendors pose the most significant risk to an organization’s security posture.

For a deep dive into Vendor Risk Management, read this post.

These insights, coupled with an ability to project the impact of selected 

remediation tasks, help response teams optimize their risk treatment efforts, supporting the continuous improvement objectives of ISO 3100

Remediation impact projections on the UpGuard platform.

Another form of risk treatment is to outsource the responsibility to a third party. For example, third-party risk management, the process of managing security risks caused by third-party vendors, could be outsourced to a team of cybersecurity experts. Your organization will still be responsible for the outcome of detected risks but without the added burden of also having to manage them.

The benefit of reduced internal resources makes outsourcing third-party risk management a very economical choice for scaling businesses.

Watch this video to learn about UpGuard’s Third-Party Risk Management Service.

Monitoring and Review

Evaluating the effectiveness of your implemented risk framework will determine whether or not your ISO 31000 risk management program was a profitable investment. During each review and iteration process, be sure to keep the human and cultural factor principle front of mind – don’t forget the people impacted by each iteration. 

Your risk mitigation objectives shouldn’t be so ambitious that you must handcuff your employees. You need to strike the perfect balance between risk management, risk acceptance, and employee well-being.

Recording and Reporting

Finally, all risk management activities should be recorded. Not only will this support stakeholders with their ongoing risk-based strategic decisions, but it will also provide you with a reference for tracking your management systems maturity throughout the ISO 31000 implementation lifecycle.

The Windows Server Hardening Checklist 2023

UpGuard Team
updated Jan 08, 2023

Whether you’re deploying hundreds of Windows servers into the cloud, or handbuilding physical servers for a small business, having a proper method to ensure a secure, reliable environment is crucial to keeping your ecosystem safe from data breaches.

Everyone knows that an out-of-the-box Windows server may not have all the necessary security measures in place to go right into production, although Microsoft has been improving the default configuration in every server version. UpGuard presents this ten step checklist to ensure that your Windows servers have been sufficiently hardened against most cyber attacks.

Specific best practices differ depending on need, but addressing these ten areas before subjecting a server to the internet will protect against the most common exploits. Many of these are standard recommendations that apply to servers of any flavor, while some are Windows specific, delving into some of the ways you can tighten up the Microsoft server platform. Details on hardening Linux servers can be found in our article 10 Essential Steps to Configuring a New Server.

1. User configurationProtect your credentials
2. Network configurationEstablish communications
3. Features and roles configurationAdd what you need, remove what you don’t
4. Update installationPatch vulnerabilities
5. NTP configurationPrevent clock drift
6. Firewall configurationMinimize your external footprint
7. Remove access configurationHarden remote administration sessions
8. Service configurationMinimize your attack surface
9. Further hardeningProtect the OS and other applications
10. Logging and monitoringKnow what’s happening on your system
11. Frequently asked questionsCommon questions about server hardening

1. User Configuration

Modern Windows Server editions force you to do this, but make sure the password for the local Administrator account is reset to something secure. Furthermore, disable the local administrator whenever possible. There are very few scenarios where this account is required and because it’s a popular target for attack, it should be disabled altogether to prevent it from being exploited.

With that account out of the way, you need to set up an admin account to use. You can either add an appropriate domain account, if your server is a member of an Active Directory (AD), or create a new local account and put it in the administrators group. Either way, you may want to consider using a non-administrator account to handle your business whenever possible, requesting elevation using Windows sudo equivalent, “Run As” and entering the password for the administrator account when prompted.

Verify that the local guest account is disabled where applicable. None of the built-in accounts are secure, guest perhaps least of all, so just close that door. Double check your security groups to make sure everyone is where they are supposed to be (adding domain accounts to the remote desktop users group, for example.)

Don’t forget to protect your passwords. Use a strong password policy to make sure accounts on the server can’t be compromised. If your server is a member of AD, the password policy will be set at the domain level in the Default Domain Policy. Stand alone servers can be set in the local policy editor. Either way, a good password policy will at least establish the following:

  • Complexity and length requirements – how strong the password must be
  • Password expiration – how long the password is valid
  • Password history – how long until previous passwords can be reused
  • Account lockout – how many failed password attempts before the account is suspended

Old passwords account for many successful hacks, so be sure to protect against these by requiring regular password changes.

2. Network Configuration

Production servers should have a static IP so clients can reliably find them. This IP should be in a protected segment, behind a firewall. Configure at least two DNS servers for redundancy and double check name resolution using nslookup from the command prompt. Ensure the server has a valid A record in DNS with the name you want, as well as a PTR record for reverse lookups. Note that it may take several hours for DNS changes to propagate across the internet, so production addresses should be established well before a go live window. Finally, disable any network services the server won’t be using, such as IPv6. This depends on your environment and any changes here should be well-tested before going into production.

3. Windows Features and Roles Configuration

Microsoft uses roles and features to manage OS packages. Roles are basically a collection of features designed for a specific purpose, so generally roles can be chosen if the server fits one, and then the features can be customized from there. Two equally important things to do are 1) make sure everything you need is installed. This might be a .NET framework version or IIS, but without the right pieces your applications won’t work. 2) Uninstall everything you don’t need. Extraneous packages unnecessarily extend the attack surface of the server and should be removed whenever possible. This is equally true for default applications installed on the server that won’t be used. Servers should be designed with necessity in mind and stripped lean to make the necessary parts function as smoothly and quickly as possible.

4. Update Installation

This may seem to go without saying, but the best way to keep your server secure is to keep it up to date. This doesn’t necessarily mean living on the cutting edge and applying updates as soon as they are released with little to no testing, but simply having a process to ensure updates do get applied within a reasonable window. Most exploited vulnerabilities are over a year old, though critical updates should be applied as soon as possible in testing and then in production if there are no problems. 

There are different kinds of updates: patches tend to address a single vulnerability; roll-ups are a group of packages that address several, perhaps related vulnerability, and service packs are updates to a wide range of vulnerabilities, comprised of dozens or hundreds of individual patches. Be sure to peek into the many Microsoft user forums after an update is released to find out what kind of experience other people are having with it. Keep in mind that the version of the OS is a type of update too, and using years-old server versions puts you well behind the security curve.

If your production schedule allows it, you should configure automatic updates on your server. Unfortunately, the manpower to review and test every patch is lacking from many IT shops and this can lead to stagnation when it comes to installing updates. It’s much more dangerous, however, to leave a production system unpatched than to automatically update it, at least for critical patches. If at all possible, the updates should be staggered so test environments receive them a week or so earlier, giving teams a chance to observe their behavior. Optional updates can be done manually, as they usually address minor issues.

Other MS software updates through Windows Update as well, so make sure to turn on updates for other products if you’re running Exchange, SQL or another MS server technology. Each application should be updated regularly and with testing.

5. NTP Configuration

A time difference of merely 5 minutes will completely break Windows logons and various other functions that rely on Kerberos authentication. Servers that are domain members will automatically have their time synched with a domain controller upon joining the domain, but stand alone servers need to have NTP set up to sync to an external source so the clock remains accurate. Domain controllers should also have their time synched to a time server, ensuring the entire domain remains within operational range of actual time.

6. Firewall Configuration

If you’re building a web server, for example, you’re only going to want web ports (80 and 443) open to that server from the internet. If anonymous internet clients can talk to the server on other ports, that opens a huge and unnecessary security risk. If the server has other functions such as remote desktop (RDP) for management, they should only be available over a VPN connection, ensuring that unauthorized people can’t exploit the port at will from the net.

The Windows firewall is a decent built-in software firewall that allows configuration of port-based traffic from within the OS. On a stand alone server, or any server without a hardware firewall in front of it, the Windows firewall will at least provide some protection against network based attacks by limiting the attack surface to the allowed ports. That said, a hardware firewall is always a better choice because it offloads the traffic to another device and offers more options on handling that traffic, leaving the server to perform its main duty. Whichever method you use, the key point is to restrict traffic to only necessary pathways.

7. Remote Access Configuration

As mentioned above, if you use RDP, be sure it is only accessible via VPN if at all possible. Leaving it open to the internet doesn’t guarantee you’ll get hacked, but it does offer potential hackers another inroad into your server.

Make sure RDP is only accessible by authorized users. By default, all administrators can use RDP once it is enabled on the server. Additional people can join the Remote Desktop Users group for access without becoming administrators.

In addition to RDP, various other remote access mechanisms such as Powershell and SSH should be carefully locked down if used and made accessible only within a VPN environment. Telnet should never be used at all, as it passes information in plain text and is woefully insecure in several ways. Same goes for FTP. Use SFTP or SSH (from a VPN) whenever possible and avoid any unencrypted communications altogether.

8. Service Configuration

Windows server has a set of default services that start automatically and run in the background. Many of these are required for the OS to function, but some are not and should be disabled if not in use. Following the same logic as the firewall, we want to minimize the attack surface of the server by disabling everything other than primary functionality. Older versions of MS server have more unneeded services than newer, so carefully check any 2008 or 2003 (!) servers.

Important services should be set to start automatically so that the server can recover without human interaction after failure. For more complex applications, take advantage of the Automatic (Delayed Start) option to give other services a chance to get going before launching intensive application services. You can also set up service dependencies in which a service will wait for another service or set of services to successfully start before starting. Dependencies also allow you to stop and start an entire chain at once, which can be helpful when timing is important.

Finally, every service runs in the security context of a specific user. For default Windows services, this is often as the Local System, Local Service or Network Service accounts. This configuration may work most of the time, but for application and user services, best practice dictates setting up service specific accounts, either locally or in AD, to handle these services with the minimum amount of access necessary. This keeps malicious actors who have compromised an application from extending that compromise into other areas of the server or domain.

9. Further Hardening

Microsoft provides best practices analyzers based on role and server version that can help you further harden your systems by scanning and making recommendations.

Although User Account Control (UAC) can get annoying, it serves the important purpose of abstracting executables from the security context of the logged in user. This means that even when you’re logged in as an admin, UAC will prevent applications from running as you without your consent. This prevents malware from running in the background and malicious websites from launching installers or other code. Leave UAC on whenever possible.

The tips in this guide help secure the Windows operating system, but every application you run should be hardened as well. Common Microsoft server applications such as MSSQL and Exchange have specific security mechanisms that can help protect them against attacks like ransomware such as WannaCry, be sure to research and tweak each application for maximum resilience. If you’re building a web server, you can also follow our hardening guide to improve its internet facing security.

10. Logging and Monitoring

Finally, you need to make sure that your logs and monitoring are configured and capturing the data you want so that in the event of a problem, you can quickly find what you need and remediate it. Logging works differently depending on whether your server is part of a domain. Domain logons are processed by domain controllers, and as such, they have the audit logs for that activity, not the local system. Stand alone servers will have security audits available and can be configured to show passes and/or failures.

Check the max size of your logs and scope them to an appropriate size. Log defaults are almost always far too small to monitor complex production applications. As such, disk space should be allocated during server builds for logging, especially for applications like MS Exchange. Logs should be backed up according to your organization’s retention policies and then cleared to make room for more current events.

Consider a centralized log management solution if handling logs individually on servers gets overwhelming. Like a syslog server in the Linux world, a centralized event viewer for Windows servers can help speed up troubleshooting and remediation times for medium to large environments.

Establish a performance baseline and set up notification thresholds for important metrics. Whether you use the built-in Windows performance monitor, or a third party solution that uses a client or SNMP to gather data, you need to be gathering performance info on every server. Things like available disk space, processor and memory use, network activity and even temperature should be constantly analyzed and recorded so anomalies can be easily identified and dealt with. This step is often skipped over due to the hectic nature of production schedules, but in the long run it will pay dividends because troubleshooting without established baselines is basically shooting in the dark.

11. Frequently Asked Questions About Windows Server Hardening

What is Server Hardening?

Hardening is a catch-all term for the changes made in configuration, access control, network settings and server environment, including applications, in order to improve the server security and overall security of an organization’s IT infrastructure. Different benchmarks exist for Windows server hardening, including Microsoft Security Benchmarks as well as CIS Benchmark hardening standards established by the Center For Internet Security. Benchmarks from CIS cover network security hardening for cloud platforms such as Microsoft Azure as well as application security policy for software such as Microsoft SharePoint, along with database hardening for Microsoft SQL Server, among others. 

How Do l Harden a Web Server?

It’s good practice to follow a standard web server hardening process for new servers before they go into production. Never attempt to harden web servers in use as this can affect your production workloads, with unpredictable disruptions, so instead, provision fresh servers for hardening, then migrate your applications after hardening and fully testing the setup. A good first step when hardening a Windows web server involves patching the server with the latest service packs from Microsoft before moving on to securing your web server software such as Microsoft IIS, Apache, PHP, or Nginx. 

Harden system access and configure network traffic controls, including setting minimum password length, configure Windows Firewall, which allows you to implement functionality similar to iptables using traffic policy, set up a hardware firewall if one is available, and configure your audit policy as well as log settings. Eliminate potential backdoors that can be used by an attacker, starting at the firmware level, by ensuring your servers have the latest BIOS firmware that is hardened against firmware attacks, all the way to IP address rules for limiting unauthorized access, and uninstalling unused services or unnecessary software. Make sure all file system volumes use the NTFS filesystem, and configure file permissions to limit user permission to least privilege access. You should also install anti-virus software as part of your standard server security configuration, ideally with daily updates and real-time protection.  

What is the Most Important Process in Windows Server Hardening?

To really secure your servers against the most common attacks, you must adopt something of the hacker mindset yourself, which means scanning for potential vulnerabilities from the viewpoint of how a malicious attacker might look for an opening. Inevitably, the largest hacks tend to occur when servers have poor or incorrect access control permissions, ranging from lax file system permissions to network and device permissions. In a statistical study of recent security breaches, poor access management to be the root cause behind an overwhelming majority of data breaches, with 74% of breaches involving the use of a privileged account in some capacity or the other. 

Perhaps the most dangerous but pervasive form of poor access control is granting of Everyone Write/Modify or Read permissions on files and folders with sensitive contents, which occurs so frequently as a natural offshoot of complex organizational collaborative team structures. To reduce exposure through access control, set group policy and permissions to the minimum privileges acceptable, and consider implementing strict protocols such as 2 Factor Authentication as well as zero trust privilege to ensure resources are only accessed by authenticated actors. 

Other common areas of vulnerability include social engineering and servers running with unpatched software, for which your team should undergo regular cybersecurity training and you should be regularly testing and applying the most recent security patches for software running on your servers. On this last one, you want to remove unnecessary services from your servers as these hurt the security of your IT infrastructure in two crucial ways, firstly by broadening the attacker’s potential target area, as well as by running old services in the background that might be several patches behind. These can be attractive targets for exploits. In reality, there is no system hardening silver bullet that will secure your Windows server against any and all attacks. The best hardening process follows information security best practices end to end, from hardening the operating system itself to application and database hardening.  

Which Windows Server Version is the Most Secure?

The latest versions of Windows Server tend to be the most secure since they use the most current server security best practices. For cutting edge server security, you should be looking at recent versions, including Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2016, and the most recent release, Windows Server 2019. Microsoft has added significantly to the security profile of its server OS in Windows Server 2019, with far-reaching security-focused updates that acknowledge the widespread impact of breaches and attacks. These new features make Windows Server 2019 the most formidable of the line from a security perspective. 

Windows Server 2019 features such as Windows Defender ATP Exploit Guard and Attack Surface Reduction(ASR) help to lock down your systems against intrusion and provide advanced tools for blocking malicious file access, scripts, ransomware, and other attacks. Network protection features in Windows Server 2019 provide protection against web attacks through IP blocking to eliminate outbound processes to untrusted hosts. Advanced audit policy settings in Windows Server 2019, including the Microsoft Defender Advanced Threat Protection Incidents queue help you get a granular event log for monitoring threats that require manual action or follow up.  

Final Thoughts

Defining your ideal state is an important first step for server management. Building new servers to meet that ideal takes it a step further. But creating a reliable and scalable server management process requires continuous testing of actual state against the expected ideal. This is because configurations drift over time: updates, changes made by IT, integration of new software– the causes are endless.

What is Firewall Design?


firewall is a network security device designed to monitor and control network traffic flow based on predetermined security rules. It acts as a barrier, selectively allowing or blocking incoming and outgoing network connections to protect the internal network from external threats. Essentially, a firewall ensures that only authorized and secure connections are made by filtering network traffic based on defined criteria.

Firewalls operate using a combination of rule-based filtering and packet inspection techniques. When network traffic passes through a firewall, it undergoes scrutiny based on various parameters, including source and destination IP addresses, ports, protocols, and the state of connections.

The Importance of Firewall Design for Network Security

So how does firewall design impact your network security? Here are the top reasons.

Protecting Against Unauthorized Access

One of the primary functions of firewall design is to prevent unauthorized access to an organization’s network resources. Firewalls act as gatekeepers, examining incoming and outgoing network traffic and enforcing access control policies based on predefined rules.

Identifying and configuring firewalls carefully will help organizations prevent unauthorized access by ensuring that only legitimate connections are allowed.

Mitigating Cyber Threats

Firewalls employ packet filtering, deep packet inspection, and stateful inspection to analyze network traffic and identify potential threats. They can detect and block suspicious or malicious traffic. Organizations can reduce the risk of successful attacks and protect their networks and sensitive information.

Preventing Data Breaches

Data breaches can severely affect organizations, resulting in financial losses, reputational damage, and legal liabilities. Firewall design prevents data breaches by monitoring and controlling network traffic. Also, firewall design principles advocate for network segmentation, which helps contain potential breaches and limit the impact on critical assets.

Enforcing Security Policies

Firewall design allows organizations to enforce and manage their security policies effectively. Organizations can align firewall configurations with security objectives and compliance requirements by defining rules and access controls.

Firewall policies can be customized based on traffic, user roles, and data sensitivity. Regular review and updates of firewall policies can ensure the effectiveness of their security measures.

Compliance with Regulations

Compliance with industry regulations and data protection laws is crucial for organizations across various sectors. Firewall design plays a significant role in achieving compliance by implementing security controls and access restrictions mandated by regulatory frameworks.

Organizations can demonstrate their commitment to protecting sensitive data by enforcing policies in line with GDPR, HIPAA, or PCI DSS regulations.

Characteristics of a Firewall

1. Physical Barrier

A firewall is a physical barrier between an internal network and the external world. It inspects incoming and outgoing network traffic, allowing or blocking connections based on predetermined security rules. By serving as a protective boundary, a firewall helps safeguard the internal network from unauthorized access and potential threats.

2. Multi-Purpose

A firewall is a versatile security tool that performs various functions beyond basic network traffic filtering. It can support additional security features, such as intrusion detection/prevention systems, VPN connectivity, antivirus scanning, content filtering, and more. This multi-purpose nature enables firewalls to provide comprehensive security measures tailored to an organization’s needs.

3. Security Platform

Firewalls serve as a security platform by integrating different security mechanisms into a unified system. They combine packet filtering, stateful inspection, application-level gateways, and other security technologies to protect against cyber threats. By functioning as a consolidated security platform, firewalls offer a layered defense strategy against potential attacks.

4. Flexible Security Policies

Firewalls offer flexible security policy implementation, allowing organizations to define and enforce customized rules and access controls. These policies can be based on various factors, including source/destination IP addresses, ports, protocols, user identities, and time of day.

With the ability to tailor security policies to specific requirements, organizations can effectively manage network traffic and adapt to evolving security needs.

5. Access Handler

A firewall acts as an access handler by controlling and managing network access permissions. It determines what connections are allowed or denied using predefined rules and policies. By regulating access to network resources, a firewall ensures that only authorized users and devices can establish connections, reducing the risk of unauthorized access and potential data breaches.

Firewall Design Principles

It is important to remember certain principles when designing a firewall to ensure its effectiveness in safeguarding network security. These principles serve as guidelines for architects and administrators, helping them design robust firewall architectures that protect against unauthorized access and potential threats.

  • Defense-in-Depth Approach: A fundamental principle in firewall design is adopting a defense-in-depth strategy. Rather than relying solely on a single firewall, organizations should deploy multiple firewalls, intrusion detection/prevention systems, and other security measures to create a layered defense architecture. 
  • Least Privilege Principle: The principle of least privilege is crucial in firewall design to minimize the potential attack surface. It advocates granting the minimum level of privileges and access necessary for users and systems to perform their required functions. This minimizes exposure to potential threats and reduces the risk of unauthorized access or malicious activities.
  • Rule Set Optimization: Firewall rule set optimization is another important design principle. As firewalls employ rule-based filtering mechanisms, regularly reviewing and optimizing the rule sets is essential. This involves removing unnecessary or redundant rules, consolidating overlapping rules, and organizing rules logically and efficiently. 
  • Secure Default Configurations: Firewall design should prioritize secure default configurations to ensure a strong foundation for network security. Default settings often allow all traffic, leaving the network vulnerable to attacks. Secure defaults are a starting point for designing effective firewall policies and help prevent misconfigurations that may lead to security gaps.
  • Regular Monitoring and Updates: Monitoring and updating firewalls are critical principles in firewall design. Regular monitoring allows organizations to promptly detect and respond to security incidents, identify unauthorized access attempts, and analyze network traffic patterns.
