This World Password Day consider ditching passwords altogether

Did you know that May 5, 2022, is World Password Day?1 Created by cybersecurity professionals in 2013 and designated as the first Thursday every May, World Password Day is meant to foster good password habits that help keep our online lives secure. It might seem strange to have a day set aside to honor something almost no one wants to deal with—like having a holiday for filing your income taxes (actually, that might be a good idea). But in today’s world of online work, school, shopping, healthcare, and almost everything else, keeping our accounts secure is more important than ever. Passwords are not only hard to remember and keep track of, but they’re also one of the most common entry points for attackers. In fact, there are 921 password attacks every second—nearly doubling in frequency over the past 12 months.2

But what if you didn’t have to deal with passwords at all? Last fall, we announced that anyone can completely remove the password from their Microsoft account. If you’re like me and happy to ditch passwords completely, read on to learn how Microsoft is making it possible to start enjoying a passwordless life today. Still, we know not everyone is ready to say goodbye to passwords, and it’s not possible for all your online accounts. We’ll also go over some easy ways to improve your password hygiene, as well as share some exciting news from our collaboration with the FIDO Alliance about a new way to sign in without a password.  

Free yourself with passwordless sign-in

Yes, you can now enjoy secure access to your Microsoft account without a password. By using the Microsoft Authenticator app, Windows Hello, a security key, or a verification code sent to your phone or email, you can go passwordless with any of your Microsoft apps and services. Just follow these five steps:

  1. Download and install Microsoft Authenticator (linked to your personal Microsoft account).
  2. Sign in to your Microsoft account.
  3. Choose Security. Under Advanced security options, you’ll see Passwordless account in the section titled Additional security.
  4. Select Turn on.
  5. Approve the notification from Authenticator.

Notification from Microsoft Authenticator app confirming user's password has been removed.

Once you approve the notification, you’ll no longer need a password to access your Microsoft accounts. If you decide you prefer using a password, you can always go back and turn off the passwordless feature. Here at Microsoft, nearly 100 percent of our employees use passwordless options to log into their corporate accounts.

Strengthen security with multifactor authentication

One simple step we can all take to protect our accounts today is adding multifactor authentication, which blocks 99.9 percent of account compromise attacks. The Microsoft Authenticator app is free and provides multiple options for authentication, including time-based one-time passcodes (TOTP), push notifications, and passwordless sign-in—all of which work for any site that supports multifactor authentication. Authenticator is available for Android and iOS and gives you the option to turn two-step verification on or off. For your Microsoft Account, multifactor authentication is usually only needed the first time you sign in or after changing your password. Once your device is recognized, you’ll just need your primary sign-in.

Make sure your password isn’t the weak link

Rather than keeping attackers out, weak passwords often provide a way in. Using and reusing simple passwords across different accounts might make our online life easier, but it also leaves the door open. Attackers regularly scroll social media accounts looking for birthdates, vacation spots, pet names and other personal information they know people use to create easy-to-remember passwords. A recent study found that 68 percent of people use the same password for different accounts.3 For example, once a password and email combination has been compromised, it’s often sold on the dark web for use in additional attacks. As my friend Bret Arsenault, our Chief Information Security Officer (CISO) here at Microsoft, likes to say, “Hackers don’t break in, they log in.”

Some basics to remember—make sure your password is:

  • At least 12 characters long.
  • A combination of uppercase and lowercase letters, numbers, and symbols.
  • Not a word that can be found in a dictionary, or the name of a person, product, or organization.
  • Completely different from your previous passwords.
  • Changed immediately if you suspect it may have been compromised.

Tip: Consider using a password manager. Microsoft Edge and Microsoft Authenticator can create (and remember) strong passwords using Password Generator, and then automatically fill them in when accessing your accounts. Also, keep these other tips in mind:

  • Only share personal information in real-time—in person or by phone. (Be careful on social media.)
  • Be skeptical of messages with links, especially those asking for personal information.
  • Be on guard against messages with attached files, even from people or organizations you trust.
  • Enable the lock feature on all your mobile devices (fingerprint, PIN, or facial recognition).
  • Ensure all the apps on your device are legitimate (only from your device’s official app store).
  • Keep your browser updated, browse in incognito mode, and enable Pop-Up Blocker.
  • Use Windows 11 and turn on Tamper Protection to protect your security settings.

Tip: When answering security questions, provide an unrelated answer. For example, Q: “Where were you born?” A: “Green.” This helps throw off attackers who might use information skimmed from your social media accounts to hack your passwords. (Just be sure the unrelated answers are something you’ll remember.)

Passwordless authentication is becoming commonplace

As part of a historic collaboration, the FIDO Alliance, Microsoft, Apple, and Google have announced plans to expand support for a common passwordless sign-in standard. Commonly referred to as passkeys, these multi-device FIDO credentials offer users a platform-native way to safely and quickly sign in to any of their devices without a password. Virtually unable to be phished and available across all your devices, a passkey lets you sign in simply by authenticating with your face, fingerprint, or device PIN.

In addition to a consistent user experience and enhanced security, these new credentials offer two other compelling benefits:

  1. Users can automatically access their passkeys on many of their devices without having to re-enroll for each account. Simply authenticate with your platform on your new device and your passkeys will be there ready to use—protecting you against device loss and simplifying device upgrade scenarios.
  2. With passkeys on your mobile device, you’re able to sign in to an app or service on nearly any device, regardless of the platform or browser the device is running. For example, users can sign in on a Google Chrome browser that’s running on Microsoft Windows, using a passkey on an Apple device.

These new capabilities are expected to become available across Microsoft, Apple, and Google platforms starting in the next year. This type of Web Authentication (WebAuthn) credential represents a new era of authentication, and we’re thrilled to join the FIDO Alliance and others in the industry in supporting a common standard for a safe, consistent authentication experience.

Everything you need to know to create a Vulnerability Assessment Report

You’ve been asked for a Vulnerability Assessment Report for your organisation and for some of you reading this article, your first thought is likely to be “What is that?”

Worry not. This article will answer that very question as well as why you need a Vulnerability Assessment Report and where you can get one from.

As it’s likely the request for such a report came from an important source such as the Board, a partner, a client or an auditor, there isn’t a moment to waste. So let’s drive straight in.

What is a Vulnerability Assessment Report and why do you need one?

A Vulnerability Assessment Report is simply a document that illustrates how you are managing your organisation’s vulnerabilities. It’s important because, with tens of thousands of new technology flaws being discovered every year, you need to be able to prove that your organisation does its best to avoid attack if you want to be trusted by partners and customers.

A best security practice recommended by governments across the world, a vulnerability assessment is an automated review process that provides insights into your current security state. The vulnerability assessment report is the outcome of this review. Used as a roadmap to a better state of security preparedness, it lays out the unique risks your organisation is up against due to the technology you use, and reveals how best to overcome them with minimal disruption to your core business strategy and operations.

The help it provides is clear but why do you need one? As mentioned above, it’s likely you were asked for a Vulnerability Assessment Report by the Board, a partner, a client or an auditor as each of these groups needs reassurance that you’re on top of any weaknesses in your infrastructure. Here’s why:

— Customers need to trust you

Weaknesses in your IT systems could affect your customers’ operations. With supply chain attacks on the rise, a vulnerability in a single company could leave the whole range of organizations paralysed, as demonstrated by the infamous SolarWinds hack last year.

It doesn’t matter how small your business is; if your customers will be entrusting you with any of their data, they may wish for a Vulnerability Assessment Report first to confirm that your IT security practices are tiptop.

— The Board wants a better understanding of the business’ risk

Cyber security is a growing concern across many businesses, so chances are your board members want to take a better grip of their risk, before the lack of insights into vulnerabilities is turned into a much more serious business problem. With ransomware attacks regularly making headlines, having proper vulnerability management in place and presenting an “all clear” report, can give your business heads that needed peace of mind.

— Your auditors are checking for compliance

Many of the regulatory or compliance frameworks related to security and privacy, like SOC2, HIPAA, GDPR, ISO 27001, and PCI DSS, advise or outright require regular compliance scans and reporting, so if the request for a vulnerability assessment report was made by your auditor, it is likely to be for compliance purposes.

— Your CFO is renewing your cyber insurance

It could be the case that your insurance provider is seeking a vulnerability assessment report as part of the underwriting process. If you don’t want to run the risk of being denied your insurance payment or wouldn’t like to see your premiums rise, then you could benefit from supplying these reports regularly.

How often do you need to produce a vulnerability assessment report?

Regularly. Think of it like vulnerability scanning: For maximum efficacy, you need to conduct regular, if not constant, comprehensive evaluations of your entire technology stack, otherwise you could miss something that could bring your business to a costly halt.

Cybercriminals do not stop searching until they find something they can take advantage of. You need to scan your systems continuously and have up to date reporting to reflect your vigilance as and when it’s needed.

Modern vulnerability scanning solutions, like Intruder, will give you a cyber hygiene score which enables you to track the progress of your vulnerability management efforts over time, proving that your security issues are being continuously resolved in good time.‍

A vulnerability assessment report from Intruder, to provide evidence to your customers or regulators that a vulnerability scanning process is in place.

What should be included in a vulnerability assessment report?

Unfortunately, there isn’t a one size fits all report. While the contents are generally the number of vulnerabilities detected in your systems at a point in time, your different stakeholders will require varying levels of detail. Even for compliance purposes, vulnerability assessment reporting requirements can differ.

As a good rule of thumb, we recommend building an Executive Report containing graph views and composite cyber hygiene scores for the Board and C-Suite that clue them in on where they stand at any given moment. And for your IT team, their report needs greater detail such as how to apply the correct solutions to existing problems and sidestep subsequent mistakes.

Where can you get a Vulnerability Assessment Report from?

Ensuring your Vulnerability Assessment Reports contain all the elements and information your stakeholders require can take a lot of work and expertise; which can distract your security teams from other activities that will keep your organisation secure. That is why it’s recommended to choose an external provider to produce your reports.

Before you start comparing individual vendors, make sure you have a solid understanding of your technical environment and of the specific outcomes that the vulnerability assessment should present. This is because vulnerability assessment tools are not built the same; they check for different types of weaknesses, so you need to choose the solution that best suits your requirements. Consider the features and checks you’ll require, as well as the industry standards you need to follow and your budget.

Two key elements to consider relate to reporting: firstly, how flexible the assessment provider will be with how much detail is presented (particularly if you need to present data to different audiences); and secondly, how clearly the results are communicated. Scanning results can be overwhelming but the right vendor will demystify complex security data to grant you a clear, jargon-free understanding of the risks you face.

At Intruder, reports are designed to be well-understood, whilst also maintaining all the technical detail required by IT managers and DevOps teams. Whether you’re a massive enterprise or a fledgling startup, you can generate rapid reports, create compliance paper trails, stay secure, and communicate with employees and potential investors. Intruder offers a free trial of its software, which you can activate here. Get vulnerability assessment reporting in place now.

Are bigger SSD’s faster?

It’s possible you’ve read somewhere or someone gave you the following advice: a bigger SSD is faster. That is correct. If you take a specific SSD drive model and compare its 250 GB size variant to the 1 TB variant, the bigger one will be faster.

Again, I can’t stress this enough: we’re talking about the same model from the same manufacturer – only the size differs.

In this whole idea, we’re talking about comparing something like the Kingston A400 240 GB model to the Kingston A400 960 GB model. In this example, even the manufacturer stats about 100 MB/s faster write performance.

Ok, but why is a bigger SSD faster?

To put it simply, a bigger SSD has more NAND chips ranks and more channels that they can use in parallel. This leads to faster data transfer. This is a lame simplified explanation.

This of course, varies from manufacturer to manufacturer and that is because there are different controllers out there, different things a manufacturer can do in the SSD’s firmware and so on. But usually, you’ll see a measurable difference between the low capacity drives and the higher capacity ones.

Consider the DRAM Cache

The way an SSD uses its cache is by placing data in this lower-latency area, called the cache, so future requests for that data can occur much faster. These caches are usually of two types: DRAM Cache or SLC Cache.

Fast SSDs, usually have a DRAM cache. The controller of the SSD actually has this dynamic random-access memory (DRAM). Do not confuse this with the SLC cache.

Why would you care? Well, bigger SSDs have a bigger DRAM cache. Just check Samsung’s datasheet for the 870 EVO – on page 3 you’ll see the 1TB, 2TB, and 4TB have bigger and bigger DRAM caches than the 250/500GB drives.

that is the DRAM cache. Its an additional chip!

DRAM Cache and SLC Cache are completely different animals. Yes they both do the ‘cache’ action. They both have the purpose of accelerating the drive’s speed, but the cost and logic are different.

A DRAM cache is basically a separate chip in the PCB of your SSD. This DRAM chip is responsible for the work in your SSD, just as your system RAM is responsible for the operation of your PC. It temporarily stores data for the purpose of accelerating processing.

And because of the temporary storage function of the DRAM cache, many read and write processes can directly use the data in this cache – and it is a lot faster than starting from the beginning.

When we’re talking about the SLC cache, it is not a separate chip. Because it is called a cache and it is not really a true SLC NAND Flash chip, but a part of the space in the TLC or QLC’s NAND Flash IC, it simulates the SLC writing method. It simulates it as in it writes only 1 bit of data in each cell. This does improve the read/write performance of the SSD. But not as long or as much as a DRAM cache.

But! For an SSD without a DRAM cache, just a SLC Cache, the speeds will drop dramatically after that cache is exhausted from sequential writes – thye drop to the original value of the TLC NAND Flash. For these types of SSDs, without a DRAM cache, usually the indicated read/write speed in the tech specs are measured using the SLC Cache. (the test does not get to saturate the SLC cache and the average speed is higher. But if it were to be really tested, we’d see lower numbers once the SLC Cache can’t keep up)

The bottom line is: a drive without a DRAM Cache will not be able to sustain those advertised speeds for long.

Plus, a bigger DRAM Cache means you can abuse that drive more. By abusing, I mean giving it heavy workloads like a lot of writes/reads at once.

My 2cents? Never buy a DRAM-less SSD. SSDs that have a DRAM cache are so cheap nowadays it does not make sense to trade off the performance. Heck, I’ve seen DRAM-less SSDs a couple of bucks more expensive than the ones with a DRAM cache. I don’t know why.

How to tell if that SSD has a DRAM cache?

Just look up the datasheet on the manufacturer’s website. PCpartpicker also sometimes lists this specification in the Cache column.

If I’m in a hurry, if the manufacturer does not say anything about the DRAM cache, I will assume it has none. If I really want to know, just Google some review of that model.

TBW – total bytes written

A specification where bigger drives win again, as they allow for more writes before failure.

To be fair, a normal gamer/user will probably never saturate this even if we’re talking about a small drive. It takes a lot of work to actually write so much data and usually… you’ll probably want to upgrade to a bigger or faster drive before your old SSD will fial.

Nonetheless, it is worth mentioning that the TBW figure is also bigger in a bigger SSD.

Always try to buy bigger and with DRAM Cache

Enough said. Spending a little more for a bigger drive with a DRAM cache is always worth it. Always!

Examples of popular SSDs that do have a DRAM cache:

  • Samsung 870 EVO, 860 EVO, 850 EVO, 860 PRO, 980 PRO, 960 PRO, 970 EVO drives
  • Crucial MX500 drives
  • Gigabyte Aorus Gen4 7000s
  • Patriot Ignite 960 GB
  • Kingston A2000 M.2

Do note that the list above is not complete. I’m sure I’ve missed some. Those are just some popular drives that I can actually recommend if you are looking for suggestions on what to buy – and always strive to get the biggest capacity you can afford!

Final thoughts

If there is something to remember from this whole article is this: buy as big as your budget allows you and always buy an SSD that has a DRAM Cache. These two ideas will guarantee that you’ll not be disappointed with your new SSD.

CMR vs SMR drives – what to pick? How to tell?

Buying a hard disk used to be quite easy. Now we have stuff like CMR vs SMR drives, manufacturers not being completely clear in their product showcase pages, and so on.

TLDR: To keep things short, you should strive to buy a CMR drive because SMR drives, while they work just fine, are usually slower in every typical individual test carried by a lot of people out there. SMR drives are slower as their method of writing data aims for storage density, and one of the drawbacks of this goal is speed.

And before we continue, yes, even if manufacturers have developed firwmare that optimize the read and write performance for SMR drives, they are still not that great as a CMR drive.

Tip: some great benchmarks for hard disk drives are: Crystal Disk Mark, ATTO Disk Benchmark, HD Tune, and even PCMark has some storage benchmarks.

CMR or PMR drives – how they work

CMR comes from Conventional Magnetic Recording. It is also known as PMR that comes from Perpendicular Magnetic Recording.

The way CMR works is by aligning the poles of the magnetic elements, which represent bits of data perpendicularly to the surface of the disk. The magnetic tracks are written side-by-side without overlapping.

a great image explanation from Synology for CMR / PMR drives

And because the write head is usually quite large in comparison to the read head, HDD manufacturers aim to shrinking the size of the write head – or do it as much as possible.

SMR – how do these drives work?

Shingled Magnetic Recording, or SMR, is an extension to PMR. It basically offers improved density. And this happens because rather than writing each magnetic track without overlapping, SMR overlaps each new track with part of the previous track. One way to think about it is by comparing it to the shingles on a roof.

a great image explanation from Synology for SMR drives

By overalapping the tracks, write heads become a lot thinner, and we get a bigger areal density.

CMR vs SMR drives – why does it actually matter?

In short, because you want the best performance for your dollar.

But to get a little bit more technical, regardless of whether an HDD uses CMR or SMR when some new data is written on the drive, the tracks are fully readable without performance impact.

So we have a pretty good read speed, right? No matter what we choose? Right? Kind of. Not really. Well, it depends on how you use the drive.

But! On an SMR drive, when any data is edited or overwritten, the write head will not overwrite data on the existing magnetic track. It will write the new data on an empty area of the disk. While the original track with the old data will temporarily sit put. Then, when the SMR HDD becomes idle, it will enter a ‘reorganization mode’, where the old bits of data on the original track are being erased and made available for future use.

This reorganization procedure must occur and makes idle time essential on an SMR drive. If you hit the respective SMR drive hard with write and read operations, it won’t get to do this in a fast way, and the drive will have to write new data and reorganize stuff at the same time. This causes an impact on the overall read and write performance of the drive.

How can I tell if the HDD I want to buy is SMR or CMR?

Some manufacturers make it easy, some not so much. But basically, searching with something like ‘product code SMR or CMR’ on Google will lead you to a good result most of the time.

Now, Western Digital, on their homepage in the shop section, actually lists CMR or SMR for their drives in the ‘Full Specifications’ area, at the Recording Technology specification. Neat!

For Seagate, however, you have to go to the product page, and download the PDF datasheet. Oh well, I guess it works.

Here’s a breakdown of what is what usually, at least for the common models. Please, search online or on the manufacturer’s website in case the below data becomes outdated. It was last looked up in 29.01.2022, on the manufacturers’ websites, just so you know.

When does buying a SMR drive make sense?

My opinion is that never.

But if you get an amazing price, and you know that hard drive will not get a lot of writes, edits, and deletions… well, it might make sense since the actual heavy usage of erasing,editing and writing data is causing the ‘slowness’. Like if you were to just fill it up with movies and that’s it. Those movies will not get edited, deleted or anything – they will just be read when you watch them. I guess – thinking about selfhosting something like Plex or Nextcloud… or a DIY NAS. I’d still opt for a CMR drive – what kind of discount are we talking about, to be fair? 10% is not worth it in my opinion.

Closing thoughts

Basically, aim for a CMR drive. And if you are new to the whole computer parts upgrade or stuff… don’t stress if you are buying a NAS drive for your desktop PC. It does not matter, it will work the same – maybe even last longer!

Hard disk buying is now as tedious as buying another component, I guess – one more thing to look for besides the usual specifications. I do hope that testing, developing, and working with diverse methods and technologies of storing data will eventually lead to manufacturers developing more performant and higher density hard disks. Just imagine a 100 TB HDD! That would be insane.

I hope this article helped you figure out what you need – an SMR or a CMR drive and why it matters.
