The PQXDH Key Agreement Protocol

Revision 1, 2023-05-24 [PDF]

Ehren Kret, Rolfe Schmidt

1. Introduction

This document describes the “PQXDH” (or “Post-Quantum Extended Diffie-Hellman”) key agreement protocol. PQXDH establishes a shared secret key between two parties who mutually authenticate each other based on public keys. PQXDH provides post-quantum forward secrecy and a form of cryptographic deniability but still relies on the hardness of the discrete log problem for mutual authentication in this revision of the protocol.

PQXDH is designed for asynchronous settings where one user (“Bob”) is offline but has published some information to a server. Another user (“Alice”) wants to use that information to send encrypted data to Bob, and also establish a shared secret key for future communication.

2. Preliminaries

2.1. PQXDH parameters

An application using PQXDH must decide on several parameters:

Name	Definition
curve	A Montgomery curve for which XEdDSA [1] is specified, at present this is one of curve25519 or curve448
hash	A 256 or 512-bit hash function (e.g. SHA-256 or SHA-512)
info	An ASCII string identifying the application with a minimum length of 8 bytes
pqkem	A post-quantum key encapsulation mechanism (e.g. Crystals-Kyber-1024 [2])
EncodeEC	A function that encodes a curve public key into a byte sequence
DecodeEC	A function that decodes a byte sequence into a curve public key and is the inverse of EncodeEC
EncodeKEM	A function that encodes a pqkem public key into a byte sequence
DecodeKEM	A function that decodes a byte sequence into a pqkem public key and is the inverse of EncodeKEM

For example, an application could choose curve as curve25519, hash as SHA-512, info as “MyProtocol”, and pqkem as CRYSTALS-KYBER-1024.

The recommended implementation of EncodeEC consists of a single-byte constant representation of curve followed by little-endian encoding of the u-coordinate as specified in [3]. The single-byte representation of curve is defined by the implementer. Similarly the recommended implementation of DecodeEC reads the first byte to determine the parameter curve. If the first byte does not represent a recognized curve, the function fails. Otherwise it applies the little-endian decoding of the u-coordinate for curve as specified in [3].

The recommended implementation of EncodeKEM consists of a single-byte constant representation of pqkem followed by the encoding of PQKPK specified by pqkem. The single-byte representation of pqkem is defined by the implementer. Similarly the recommended implementation of DecodeKEM reads the first byte to determine the parameter pqkem. If the first byte does not represent a recognized key encapsulation mechanism, the function fails. Otherwise it applies the decoding specified by the selected key encapsulation mechanism.

2.2. Cryptographic notation

Throughout this document, all public keys have a corresponding private key, but to simplify descriptions we will identify key pairs by the public key and assume that the corresponding private key can be accessed by the key owner.

This document will use the following notation:

The concatenation of byte sequences X and Y is X || Y.
DH(PK1, PK2) represents a byte sequence which is the shared secret output from an Elliptic Curve Diffie-Hellman function involving the key pairs represented by public keys PK1 and PK2. The Elliptic Curve Diffie-Hellman function will be either the X25519 or X448 function from [3], depending on the curve parameter.
Sig(PK, M, Z) represents the byte sequence that is a curve XEdDSA signature on the byte sequence M which was created by signing M with PK’s corresponding private key and using 64 bytes of randomness Z. This signature verifies with public key PK. The signing and verification functions for XEdDSA are specified in [1].
KDF(KM) represents 32 bytes of output from the HKDF algorithm [4] using hash with inputs:
- HKDF input key material = F || KM, where KM is an input byte sequence containing secret key material, and F is a byte sequence containing 32 0xFF bytes if curve is curve25519, and 57 0xFF bytes if curve is curve448. As in in XEdDSA [1], F ensures that the first bits of the HKDF input key material are never a valid encoding of a scalar or elliptic curve point.
- HKDF salt = A zero-filled byte sequence with length equal to the hash output length, in bytes.
- HKDF info = The concatenation of string representations of the 4 PQXDH parameters info, curve, hash, and pqkem into a single string separated with ‘_’ such as “MyProtocol_CURVE25519_SHA-512_CRYSTALS-KYBER-1024”. The string representations of the PQXDH parameters are defined by the implementer.
(CT, SS) = PQKEM-ENC(PK) represents a tuple of the byte sequence that is the KEM ciphertext, CT, output by the algorithm pqkem together with the shared secret byte sequence SS encapsulated by the ciphertext using the public key PK.
PQKEM-DEC(PK, CT) represents the shared secret byte sequence SS decapsulated from a pqkem ciphertext using the private key counterpart of the public key PK used to encapsulate the ciphertext CT.

2.3. Roles

The PQXDH protocol involves three parties: Alice, Bob, and a server.

Alice wants to send Bob some initial data using encryption, and also establish a shared secret key which may be used for bidirectional communication.
Bob wants to allow parties like Alice to establish a shared key with him and send encrypted data. However, Bob might be offline when Alice attempts to do this. To enable this, Bob has a relationship with some server.
The server can store messages from Alice to Bob which Bob can later retrieve. The server also lets Bob publish some data which the server will provide to parties like Alice. The amount of trust placed in the server is discussed in Section 4.9.

In some systems the server role might be divided between multiple entities, but for simplicity we assume a single server that provides the above functions for Alice and Bob.

2.4. Elliptic Curve Keys

PQXDH uses the following elliptic curve public keys:

Name	Definition
IK_A	Alice’s identity key
IK_B	Bob’s identity key
EK_A	Alice’s ephemeral key
SPK_B	Bob’s signed prekey
(OPK_B¹, OPK_B², …)	Bob’s set of one-time prekeys

The elliptic curve public keys used within a PQXDH protocol run must either all be in curve25519 form, or they must all be in curve448 form, depending on the curve parameter [3].

Each party has a long-term identity elliptic curve public key (IK_A for Alice, IK_B for Bob).

Bob also has a signed prekey SPK_B, which he changes periodically and signs each time with IK_B, and a set of one-time prekeys (OPK_B¹, OPK_B², …), which are each used in a single PQXDH protocol run. (“Prekeys” are so named because they are essentially protocol messages which Bob publishes to the server prior to Alice beginning the protocol run.) These keys will be uploaded to the server as described in Section 3.2.

During each protocol run, Alice generates a new ephemeral key pair with public key EK_A.

2.5. Post-Quantum Key Encapsulation Keys

PQXDH uses the following post-quantum key encapsulation public keys:

Name	Definition
PQSPK_B	Bob’s signed last-resort pqkem prekey
(PQOPK_B¹, PQOPK_B², …)	Bob’s set of signed one-time pqkem prekeys

The pqkem public keys used within a PQXDH protocol run must all use the same pqkem parameter.

Bob has a signed last-resort post-quantum prekey PQSPK_B, which he changes periodically and signs each time with IK_B, and a set of signed one-time prekeys (PQOPK_B¹, PQOPK_B², …) which are also signed with IK_B and each used in a single PQXDH protocol run. These keys will be uploaded to the server as described in Section 3.2. The name “last-resort” refers to the fact that the last-resort prekey is only used when one-time pqkem prekeys are not available. This can happen when the number of prekey bundles downloaded for Bob exceeds the number of one-time pqkem prekeys Bob has uploaded (see Section 3 for details about the role of the server).

3. The PQXDH protocol

3.1. Overview

PQXDH has three phases:

Bob publishes his elliptic curve identity key, elliptic curve prekeys, and pqkem prekeys to a server.
Alice fetches a “prekey bundle” from the server, and uses it to send an initial message to Bob.
Bob receives and processes Alice’s initial message.

The following sections explain these phases.

3.2. Publishing keys

Bob generates a sequence of 64-byte random values Z_SPK, Z_PQSPK, Z₁, Z₂, … and publishes a set of keys to the server containing:

Bob’s curve identity key IK_B
Bob’s signed curve prekey SPK_B
Bob’s signature on the curve prekey Sig(IK_B, EncodeEC(SPK_B), Z_SPK)
Bob’s signed last-resort pqkem prekey PQSPK_B
Bob’s signature on the pqkem prekey Sig(IK_B, EncodeKEM(PQSPK_B), Z_PQSPK)
A set of Bob’s one-time curve prekeys (OPK_B¹, OPK_B², OPK_B³, …)
A set of Bob’s signed one-time pqkem prekeys (PQOPK_B¹, PQOPK_B², PQOPK_B³, …)
The set of Bob’s signatures on the signed one-time pqkem prekeys (Sig(IK_B, EncodeKEM(PQOPK_B¹), Z₁), Sig(IK_B, EncodeKEM(PQOPK_B²), Z₂), Sig(IK_B, EncodeKEM(PQOPK_B³), Z₃), …)

Bob only needs to upload his identity key to the server once. However, Bob may upload new one-time prekeys at other times (e.g. when the server informs Bob that the server’s store of one-time prekeys is getting low).

For both the signed curve prekey and the signed last-resort pqkem prekey, Bob will upload a new prekey along with its signature using IK_B at some interval (e.g. once a week or once a month). The new signed prekey and its signatures will replace the previous values.

After uploading a new pair of signed curve and signed last-resort pqkem prekeys, Bob may keep the private key corresponding to the previous pair around for some period of time to handle messages using it that may have been delayed in transit. Eventually, Bob should delete this private key for forward secrecy (one-time prekey private keys will be deleted as Bob receives messages using them; see Section 3.4).

3.3. Sending the initial message

To perform a PQXDH key agreement with Bob, Alice contacts the server and fetches a “prekey bundle” containing the following values:

Bob’s curve identity key IK_B
Bob’s signed curve prekey SPK_B
Bob’s signature on the curve prekey Sig(IK_B, EncodeEC(SPK_B), Z_SPK)
One of either Bob’s signed one-time pqkem prekey PQOPK_Bⁿ or Bob’s last-resort signed pqkem prekey PQSPK_B if no signed one-time pqkem prekey remains. Call this key PQPK_B.
Bob’s signature on the pqkem prekey Sig(IK_B, EncodeKEM(PQPK_B), Z_PQPK)
(Optionally) Bob’s one-time curve prekey OPK_Bⁿ

The server should provide one of Bob’s curve one-time prekeys if one exists and then delete it. If all of Bob’s curve one-time prekeys on the server have been deleted, the bundle will not contain a one-time curve prekey element.

The server should prefer to provide one of Bob’s pqkem one-time signed prekeys PQOPK_Bⁿ if one exists and then delete it. If all of Bob’s pqkem one-time signed prekeys on the server have been deleted, the bundle will instead contain Bob’s pqkem last-resort signed prekey PQSPK_B.

Alice verifies the signatures on the prekeys. If any signature check fails, Alice aborts the protocol. Otherwise, if all signature checks pass, Alice then generates an ephemeral curve key pair with public key EK_A. Alice additionally generates a pqkem encapsulated shared secret:

    (CT, SS) = PQKEM-ENC(PQPK_B)
               shared secret SS
               ciphertext CT

If the bundle does not contain a curve one-time prekey, she calculates:

    DH₁ = DH(IK_A, SPK_B)
    DH₂ = DH(EK_A, IK_B)
    DH₃ = DH(EK_A, SPK_B)
    SK = KDF(DH₁ || DH₂ || DH₃ || SS)

If the bundle does contain a curve one-time prekey, the calculation is modified to include an additional DH:

DH₄ = DH(EK_A, OPK_B)
SK = KDF(DH₁ || DH₂ || DH₃ || DH₄ || SS)

After calculating SK, Alice deletes her ephemeral private key, the DH outputs, the shared secret SS, and the ciphertext CT.

Alice then calculates an “associated data” byte sequence AD that contains identity information for both parties:

AD = EncodeEC(IK_A) || EncodeEC(IK_B)

Alice may optionally append additional information to AD, such as Alice and Bob’s usernames, certificates, or other identifying information.

Alice then sends Bob an initial message containing:

Alice’s identity key IK_A
Alice’s ephemeral key EK_A
The pqkem ciphertext CT encapsulating SS for PQPK_B
Identifiers stating which of Bob’s prekeys Alice used
An initial ciphertext encrypted with some AEAD encryption scheme [5] using AD as associated data and using an encryption key which is either SK or the output from some cryptographic PRF keyed by SK.

The initial ciphertext is typically the first message in some post-PQXDH communication protocol. In other words, this ciphertext typically has two roles, serving as the first message within some post-PQXDH protocol, and as part of Alice’s PQXDH initial message.

The initial message must be encoded in an unambiguous format to avoid confusion of the message items by the recipient.

After sending this, Alice may continue using SK or keys derived from SK within the post-PQXDH protocol for communication with Bob, subject to the security considerations discussed in Section 4.

3.4. Receiving the initial message

Upon receiving Alice’s initial message, Bob retrieves Alice’s identity key and ephemeral key from the message. Bob also loads his identity private key and the private key(s) corresponding to the signed prekeys and one-time prekeys Alice used.

Using these keys, Bob calculates PQKEM-DEC(PQPK_B, CT) as the shared secret SS and repeats the DH and KDF calculations from the previous section to derive SK, and then deletes the DH values and SS values.

Bob then constructs the AD byte sequence using IK_A and IK_B as described in the previous section. Finally, Bob attempts to decrypt the initial ciphertext using SK and AD. If the initial ciphertext fails to decrypt, then Bob aborts the protocol and deletes SK.

If the initial ciphertext decrypts successfully, the protocol is complete for Bob. For forward secrecy, Bob deletes the ciphertext and any one-time prekey private key that was used. Bob may then continue using SK or keys derived from SK within the post-PQXDH protocol for communication with Alice subject to the security considerations discussed in Section 4.

4. Security considerations

The security of the composition of X3DH [6] with the Double Ratchet [7] was formally studied in [8] and proven secure under the Gap Diffie-Hellman assumption (GDH)[9]. PQXDH composed with the Double Ratchet retains this security against an adversary without access to a quantum computer, but strengthens the security of the initial handshake to require the solution of both GDH and Module-LWE [10]. The remainder of this section discusses an incomplete list of further security considerations.

4.1. Authentication

Before or after a PQXDH key agreement, the parties may compare their identity public keys IK_A and IK_B through some authenticated channel. For example, they may compare public key fingerprints manually, or by scanning a QR code. Methods for doing this are outside the scope of this document.

Authentication in PQXDH is not quantum-secure. In the presence of an active quantum adversary, the parties receive no cryptographic guarantees as to who they are communicating with. Post-quantum secure deniable mutual authentication is an open research problem which we hope to address with a future revision of this protocol.

If authentication is not performed, the parties receive no cryptographic guarantee as to who they are communicating with.

4.2. Protocol replay

If Alice’s initial message doesn’t use a one-time prekey, it may be replayed to Bob and he will accept it. This could cause Bob to think Alice had sent him the same message (or messages) repeatedly.

To mitigate this, a post-PQXDH protocol may wish to quickly negotiate a new encryption key for Alice based on fresh random input from Bob. This is the typical behavior of Diffie-Hellman-based ratcheting protocols [7].

Bob could attempt other mitigations, such as maintaining a blacklist of observed messages, or replacing old signed prekeys more rapidly. Analyzing these mitigations is beyond the scope of this document.

4.3. Replay and key reuse

Another consequence of the replays discussed in the previous section is that a successfully replayed initial message would cause Bob to derive the same SK in different protocol runs.

For this reason, any post-PQXDH protocol that uses SK to derive encryption keys MUST take measures to prevent catastrophic key reuse. For example, Bob could use a DH-based ratcheting protocol to combine SK with a freshly generated DH output to get a randomized encryption key [7].

4.4. Deniability

Informally, cryptographic deniability means that a protocol neither gives its participants a publishable cryptographic proof of the contents of their communication nor proof of the fact that they communicated. PQXDH, like X3DH, aims to provide both Alice and Bob deniablilty that they communicated with each other in a context where a “judge” who may have access to one or more party’s secret keys is presented with a transcript allegedly created by communication between Alice and Bob.

We focus on offline deniability because if either party is collaborating with a third party during protocol execution, they will be able to provide proof of their communication to such a third party. This limitation on “online” deniability appears to be intrinsic to the asynchronous setting [11].

PQXDH has some forms of cryptographic deniability. Motivated by the goals of X3DH, Brendel et al. [12] introduce a notion of 1-out-of-2 deniability for semi-honest parties and a “big brother” judge with access to all parties’ secret keys. Since either Alice or Bob can create a fake transcript using only their own secret keys, PQXDH has this deniability property. Vatandas, et al. [13] prove that X3DH is deniable in a different sense subject to certain “Knowledge of Diffie-Hellman Assumptions”. PQXDH is deniable in this sense for Alice, subject to the same assumptions, and we conjecture that it is deniable for Bob subject to an additional Plaintext Awareness (PA) assumption for pqkem. We note that Kyber uses a variant of the Fujisaki-Okamoto transform with implicit rejection [14] and is therefore not PA as is. However, in PQXDH, an AEAD ciphertext encrypted with the session key is always sent along with the Kyber ciphertext. This should offer the same guarantees as PA. We encourage the community to investigate the precise deniability properties of PQXDH.

These assertions all pertain to deniability in the classical setting. As discussed in [15] we expect that for future revisions of this protocol (that provide post-quantum mutual authentication) assertions about deniability against semi-honest quantum advsersaries will hold. Deniability in the face of malicious quantum adversaries requires further research.

4.5. Signatures

It might be tempting to omit the prekey signature after observing that mutual authentication and forward secrecy are achieved by the DH calculations. However, this would allow a “weak forward secrecy” attack: A malicious server could provide Alice a prekey bundle with forged prekeys, and later compromise Bob’s IK_B to calculate SK.

Alternatively, it might be tempting to replace the DH-based mutual authentication (i.e. DH₁ and DH₂) with signatures from the identity keys. However, this reduces deniability, increases the size of initial messages, and increases the damage done if ephemeral or prekey private keys are compromised, or if the signature scheme is broken.

4.6. Key compromise

Compromise of a party’s private keys has a disastrous effect on security, though the use of ephemeral keys and prekeys provides some mitigation.

Compromise of a party’s identity private key allows impersonation of that party to others. Compromise of a party’s prekey private keys may affect the security of older or newer SK values, depending on many considerations.

A full analysis of all possible compromise scenarios is outside the scope of this document, however a partial analysis of some plausible scenarios is below:

If either an elliptic curve one-time prekey (OPK_B) or a post-quantum key encapsulation one-time prekey (PQOPK_B) are used for a protocol run and deleted as specified, then a compromise of Bob’s identity key and prekey private keys at some future time will not compromise the older SK.
If one-time prekeys were not used for a protocol run, then a compromise of the private keys for IK_B, SPK_B, and PQSPK_B from that protocol run would compromise the SK that was calculated earlier. Frequent replacement of signed prekeys mitigates this, as does using a post-PQXDH ratcheting protocol which rapidly replaces SK with new keys to provide fresh forward secrecy [7].
Compromise of prekey private keys may enable attacks that extend into the future, such as passive calculation of SK values, and impersonation of arbitrary other parties to the compromised party (“key-compromise impersonation”). These attacks are possible until the compromised party replaces his compromised prekeys on the server (in the case of passive attack); or deletes his compromised signed prekey’s private key (in the case of key-compromise impersonation).

4.7. Passive quantum adversaries

PQXDH is designed to prevent “harvest now, decrypt later” attacks by adversaries with access to a quantum computer capable of computing discrete logarithms in curve.

If an attacker has recorded the public information and the message from Alice to Bob, even access to a quantum computer will not compromise SK.
If a post-quantum key encapsulation one-time prekey (PQOPK_B) is used for a protocol run and deleted as specified then compromise after deletion and access to a quantum computer at some future time will not compromise the older SK.
If post-quantum one-time prekeys were not used for a protocol run, then access to a quantum computer and a compromise of the private key for PQSPK_B from that protocol run would compromise the SK that was calculated earlier. Frequent replacement of signed prekeys mitigates this, as does using a post-PQXDH ratcheting protocol which rapidly replaces SK with new keys to provide fresh forward secrecy [7].

4.8. Active quantum adversaries

PQXDH is not designed to provide protection against active quantum attackers. An active attacker with access to a quantum computer capable of computing discrete logarithms in curve can compute DH(PK₁, PK₂) and Sig(PK, M, Z) for all elliptic curve keys PK₁, PK₂, and PK. This allows an attacker to impersonate Alice by using the quantum computer to compute the secret key corresponding to PK_A then continuing with the protocol. A malicious server with access to such a quantum computer could impersonate Bob by generating new key pairs PQSPK’_B and PQOPK’_B, computing the secret key corresponding to PK_B, then using PK_B to sign the newly generated post-quantum KEM keys and delivering these attacker-generated keys in place of Bob’s post-quantum KEM key when Alice requests a prekey bundle.

It is tempting to consider adding a post-quantum identity key that Bob could use to sign the post-quantum prekeys. This would prevent the malicious server attack described above and provide Alice a cryptographic guarantee that she is communicating with Bob, but it does not provide mutual authentication. Bob does not have any cryptographic guarantee about who he is communicating with. The post-quantum KEM and signature schemes being standardized by NIST [16] do not provide a mechanism for post-quantum deniable mutual authentication, although this can be achieved through the use of a post-quantum ring signature or designated verifier signature [12], [15]. We urge the community to work toward standardization of these or other mechanisms that will allow deniable mutual authentication.

4.9. Server trust

A malicious server could cause communication between Alice and Bob to fail (e.g. by refusing to deliver messages).

If Alice and Bob authenticate each other as in Section 4.1, then the only additional attack available to the server is to refuse to hand out one-time prekeys, causing forward secrecy for SK to depend on the signed prekey’s lifetime (as analyzed in Section 4.6).

This reduction in initial forward secrecy could also happen if one party maliciously drains another party’s one-time prekeys, so the server should attempt to prevent this (e.g. with rate limits on fetching prekey bundles).

4.10. Identity binding

Authentication as in Section 4.1 does not necessarily prevent an “identity misbinding” or “unknown key share” attack.

This results when an attacker (“Charlie”) falsely presents Bob’s identity key fingerprint to Alice as his (Charlie’s) own, and then either forwards Alice’s initial message to Bob, or falsely presents Bob’s contact information as his own. The effect of this is that Alice thinks she is sending an initial message to Charlie when she is actually sending it to Bob.

To make this more difficult the parties can include more identifying information into AD, or hash more identifying information into the fingerprint, such as usernames, phone numbers, real names, or other identifying information. Charlie would be forced to lie about these additional values, which might be difficult.

However, there is no way to reliably prevent Charlie from lying about additional values, and including more identity information into the protocol often brings trade-offs in terms of privacy, flexibility, and user interface. A detailed analysis of these trade-offs is beyond the scope of this document.

4.11. Risks of weak randomness sources

In addition to concerns about the generation of the keys themselves, the security of the PQKEM shared secret relies on the random source available to Alice’s machine at the time of running the PQKEM-ENC operation. This leads to a situation similar to what we face with a Diffie-Hellman exchange. For both Diffie-Hellman and Kyber, if Alice has weak entropy then the resulting shared secret will have low entropy when conditioned on Bob’s public key. Thus both the classical and post-quantum security of SK depend on the strength of Alice’s random source.

Kyber hashes Bob’s public key with Alice’s random bits to generate the shared secret, making Bob’s key contributory, as it is with a Diffie-Hellman key exchange. This does not reduce the dependence on Alice’s entropy source, as described above, but it does limit Alice’s ability to control the post-quantum shared secret. Not all KEMs make Bob’s key contributory and this is a property to consider when selecting pqkem.

Top 5 Security Misconfigurations Causing Data Breaches in 2023

Edward Kost
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.

UpGuard’s Risk Profile feature displays security vulnerabilities associated with end-of-life software.

To further expand its mitigation of data breach threat categories, UpGuard offersa data leak detection solution that scans ransomware blogs on the dark web for compromised credentials, and any leaked data could help hackers breach your network and sensitive resources.

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:

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

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

Ensure that the public good is the central concern during all professional computing work.
Articulate, encourage acceptance of, and evaluate fulfillment of social responsibilities by the organization or group members.
Manage personnel and resources to enhance the quality of working life.
Articulate, apply, and support policies and processes that reflect the principles of the Code.
Create opportunities for members of the organization or group to grow as professionals.
Use care when modifying or retiring systems.
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.

Uphold, promote, and respect the principles of the Code.
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.

Transparency

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.

Confidentiality

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.

Security

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.

Whistleblowing

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).

Exploring Firewall Design Principles for Secure Networks

27.07.2023

Firewall design principles are the bedrock of network security, providing a robust defense mechanism against both internal and external threats. These principles help in developing a security policy that can enforce stringent rulesets and offer layered protection for your private network.

Firewall design principles are crucial for maintaining a secure network. There are different types of firewalls like packet filter firewalls, stateful inspection firewalls, and proxy firewalls along with their unique features.

If you want to be able to design your firewall the right way you need to master the different key components in firewall design such as policies, rulesets, and interfaces, and learn the advanced features like Intrusion Prevention Systems (IPS) and Deep Packet Inspection (DPI) and be aware of best practices to implement these designs effectively.

This comprehensive understanding of firewall design principles will empower you to make informed decisions about your organization’s network security infrastructure.

What are Firewall Design Principles?

The realm of network security is complex and vast, with firewalls serving as the critical line of defense against cyber threats. They’re like the bouncers of the internet, keeping the bad guys out and letting the good guys in.

The basic concept behind firewall design principles

A firewall’s primary role is to be the gatekeeper of your network, deciding who gets in and who stays out. It’s like having a very selective doorman at an exclusive venue, only allowing those with the right credentials to enter.

The fundamental principle behind firewall design is simple: filter, filter, filter. The firewall looks at things like IP addresses, domain names, and protocols to decide if a data packet is worthy of entering your network.

Why understanding firewall design principles is essential for network security

In today’s digital age, where cyber threats are increasingly common, having a solid firewall is a must.

Understanding firewall design principles is like having a secret weapon in your security arsenal. It’s like knowing all the tricks of the trade, so you can configure your firewall to be a fortress against cyber attacks.

Staying ahead of malicious actors is possible if you understand their strategies and configure your firewall in a way that best protects against cyber threats.

No single approach will suffice when it comes to firewalls; you need to tailor yours to suit your individual needs. Take the time to understand the core firewall design principles and make your firewall the ultimate defender of your network.

Five Principles of Firewall Design

Firewall design principles are critical to protect your private network and to maximize your network security. Here are five principles you can use when establishing your firewall and implementing security policies.

1. Develop a Solid Security Policy

Having a proper security policy is an essential part of designing your firewall. Without it in place, it’s a headache to allow users to navigate the company network and restrict intruders. This proper security policy will also help you know the proper protocol if there is a security breach.

A properly developed security policy can protect you. A solid security policy includes guidance on proper internet protocol, preventing users from using devices on public networks, and recognizing external threats.

Don’t overlook a properly developed security policy! Also, remember that simply having a security policy is only the first step. In addition to establishing security policies, you should have frequent training and refreshers for all employees. Have policies in place for reporting security threats and hold everyone in the organization accountable.

2. Use a Simple Design

Keep it simple. If you have a complex design, you’ll need to find complex solutions anytime a problem arises. A simple design helps alleviate some of the pain you may feel when a problem comes up (and it inevitably will at some point). Also, complex designs are more prone to configuration errors that can open paths for external attacks.

3. Choose the Right Device

You need to have the right tools to do the job. If you use the wrong device, you have the wrong tools and are at a disadvantage from the start. Using the right part that fits your design will help you create the best firewall for your network.

4. Build a Layered Defense

Firewalls should have layers to properly protect your network. A multi-layered defense creates a complicated protection system that hackers can’t easily break through. Creating layers builds an effective defense and will keep your network safe.

5. Build Protection Against Internal Threats

Don’t just focus on attacks from external sources. A large percentage of data breaches are the result of internal threats and carelessness. Mistakes made by those internally can open your network to attacks from outside sources. Implementing proper security solutions for your internal network can help prevent this from happening.

Something as simple as accessing a web server can expose your network if you aren’t protected internally as well as you are externally.

As you design your firewall, remember these firewall design principles: have a properly developed security policy, keep it simple, use the right tools, build a layered defense, and protect yourself from internal threats.

Types of Firewalls

Different firewalls have varying characteristics and applications, so it’s essential to understand them in order to select the most suitable firewall for your network. Knowing these differences is crucial for picking the right firewall for your network’s needs.

Packet-Filtering Firewalls: Basic but Effective

A packet-filtering or packet-filter firewall does what it says—filters data packets based on predetermined rules. It checks packet headers to see what’s allowed in.

Simple, but not enough against fancy cyber threats.

Circuit-level Gateways

A circuit-level gateway can be a stand-alone system or it can be a function performed as a gateway for certain applications. A circuit-level gateway does not allow for end-to-end connection but rather sets up two connections with an inner host and a user with an outer host.

Stateful Inspection Firewalls

Stateful inspection firewalls go beyond packet headers. They keep track of active connections and use that info to validate packets. It remembers who and what is allowed – efficient and effective.

Application-level Gateways (a.k.a. Proxy Firewalls)

Proxy firewalls (also known as application-level gateways) act as intermediaries between internal networks and the Internet. They hide internal IP addresses and offer content filtering.

The choice among these types depends on your network’s needs relating to size, complexity, and sensitivity. Remember, they often work together in layers; just make sure they’re properly configured and regularly updated.

Next-Gen Firewalls

Next-gen firewalls are the next step in firewall security. These can protect against advanced malware and application-layer attacks. They typically include:

Firewall capabilities like stateful inspection.
Integrated intrusion prevention.
Application awareness and control to see risky apps.
Threat intelligence sources.
Upgrade paths to include future information feeds.
Techniques to continue evolving.

Now, we’ll explore constructing an efficient firewall.

Key Components in Firewall Design

When it comes to designing a firewall, there are certain key components that should be taken into account. Let’s break it down:

Importance of Policies

Security policies are like the rulebook for your firewall. They decide what traffic gets in and what gets blocked. You want to make sure only the right traffic makes it through.

A proper security policy will help you in both the short term and long term. Make sure to enforce security policies to keep yourself protected.

Rulesets – Defining What Gets Through

Rulesets are like the enforcers of the policies. They make sure the regulations are met. Visualize a vigilant sentry, patrolling your network for any untoward activity and taking swift action when needed. Rulesets often include elements like source address, source port, destination address, and destination port.

Interfaces – Connecting Networks Securely

Interfaces are the gateways between networks. They’re like the bridges that connect different parts of your network. Make sure these bridges are secure, so no unwanted guests can sneak in.

To recap, when it comes to firewall design, policies, rulesets, and interfaces are the key players. They work together to keep your network safe and sound.

Advanced Features in Modern Firewall Designs

In the ever-evolving world of cybersecurity, firewalls have leveled up to tackle sophisticated threats.

Let’s dive into two cool advancements: Intrusion Prevention Systems (IPS) and Deep Packet Inspection (DPI).

Intrusion Prevention Systems (IPS): Proactive Defense Mechanism

An Intrusion Prevention System (IPS) is like a superhero embedded in modern firewalls. It doesn’t just detect and block known threats; it goes the extra mile.

IPS keeps a watchful eye on network traffic, sniffing out any suspicious activity or weird anomalies. When it spots trouble, it swiftly shuts it down.

Deep Packet Inspection (DPI): Detailed Threat Analysis

Deep Packet Inspection (DPI) adds an extra layer of security by giving data packets a thorough check-up.

DPI looks at both the header info and the payload content of each packet.
It’s like a detective, figuring out the nature of incoming traffic.
If it finds anything fishy, like malware or protocol non-compliance, it sounds the alarm so you can take action.

These advanced features make modern firewalls tougher than traditional ones. But remember, no single solution can guarantee complete security.

They’re advanced elements of your security squad, but they need backup from a solid information security policy management strategy.

Four Types of Access Control

There are four techniques that firewalls generally use to control access and security policy.

User Control: Control access to a service according to which user is attempting to access the service.
Service Control: Determines what services can be accessed to keep your network secure.
Direction Control: Determines in which direction a service can be accessed, both inbound and outbound.
Behavior Control: Controls how services are accessed and used.

Advantages of Firewalls

There are several advantages of implementing a firewall to protect your network. Here are some of the biggest benefits you’ll see:

Block Infected Files

You come across threats when you browse the internet, or you might even have them delivered to your mailbox. Firewalls help block those files from breaking through your system.

Stop Unwanted Visitors

You don’t want anyone snooping through your system. This can lead to long-term security problems. Your firewall will detect unwanted visitors and keep them out.

Accessing public networks can put you at a higher risk of security breaches, but having a firewall can block access to your sensitive data.

Safeguards Your IP Address

This will protect your network as you browse the internet on a web server so you aren’t exposed to those who want to cause problems for your network. This can be set up with a virtual private network (or VPN) which acts as a network security device to keep your network secure.

Prevents Email Spamming

Security policies should help protect the employees on your network from malware or phishing attempts, but in case a mistake is made, a proper firewall can help prevent spam emails from getting through your system.

Stops Spyware

When using a web server, you can come across files that will install spyware on your system. A firewall will easily block access so you don’t have to worry about being exposed to outside threats.

Limitations of Firewalls

For as many advantages as you gain from having a firewall, there are still some limitations it will create on your server.

Internal Loose Ends

As a firewall can easily block access to external threats, it can struggle to prevent internal attacks. If you have an employee who accidentally cooperates with an attacker, you may still be exposed internally.

Infected Files

Because of the sheer number of files your network may come across, it’s impossible for every file to be reviewed by your network security device.

Cost

It can be expensive to set up a firewall that protects your system, and the bigger your network gets, the more expensive it can become. That said, even a single large data breach could cost your company dearly, so having the proper protection in place is an investment worth making.

User Restriction

Sometimes firewalls can make it more difficult for users to access the systems they need to do their work. This can impact productivity when certain users need to access multiple applications.

System Performance

Implementing a firewall takes up a lot of bandwidth and using the RAM and power supply that may need to go to other devices can impact your system’s performance.

Firewall Delivery Methods

There are several different delivery methods for a firewall. Here are some of the most common delivery methods that are used:

Software firewalls: A software firewall is a type of software that runs on your computer. It is mainly used to protect your specific device.
Hardware firewalls: This is a device that is specifically used to implement a firewall. This can protect your entire network.
Cloud firewalls: These firewalls are hosted in the cloud and are also called firewall-as-a-service (FWaaS).
