Zero Trust Explained: What It Means for Everyday Employees

Imagine that, having woken up on a regular Monday morning, you turn on your laptop at the dining table, type your password, verify your ID via a notification sent to your smartphone, and then, half an hour later, you need to verify your identity again as you try to access the payroll system. It seems that your company does not trust you anymore. And in a certain way, it doesn’t. This is zero trust security.

The company does not trust you or anybody else, and especially it does not trust an attacker who managed to steal a copy of your password.

This approach has a name: Zero Trust. Despite seeming to be an IT department concern only, Zero Trust affects every single login attempt and device you use in the workplace.

In this article, we will describe the concept of Zero Trust, compare it with the traditional model most organizations use today, and suggest several practices to implement the Zero Trust approach in your organization.

What Is Zero Trust Exactly?

By definition, Zero Trust is a security framework based on a single core idea: no trust is granted automatically, and each access attempt is checked individually. Your laptop, your account, and every application you use cannot get automatic access just because you use them on the territory of your office and via the company’s internal network.

It is worth noting that although the term is relatively new, the approach itself is quite old. As early as 2010, John Kindervag from Forrester published the report No More Chewy Centers that introduced Zero Trust. Moreover, the success of Google’s BeyondCorp project demonstrated that an enterprise could run such an approach successfully.

From a practical point of view, the Zero Trust framework asks just three simple questions on every login attempt:

• Who are you, and how can you prove it?
• Is your device up-to-date, and is the company aware of it?
• Do you actually need to access this particular piece of information in order to accomplish your task?

If the answer to all these questions is positive, you get access. Otherwise, the access attempt is restricted or blocked completely. The third question is based on the principle called least privilege. Everybody is given only the access they need and nothing more.

Zero Trust vs. Traditional Network Security Model

For many years, most enterprises used an approach resembling that of an ancient castle. Build a wall, put it around the castle, and trust everybody who passed it. Firewalls are the analogues of such walls in today’s cyber environment. Once you managed to pass it and access the company’s internal network, you could use the shared drives, resources, printers, and access other company assets with minimal verification attempts.

Such an approach was relevant in the time of office jobs. Nowadays, it is outdated as files are stored in cloud storage, employees work from home, and mobile phones are used for work-related correspondence. The term “inside” has become blurred.

Besides, there is another problem in the traditional approach: once an attacker has bypassed the firewall at the perimeter, they have free access to any network node they need. Lateral movement is the name for this phenomenon in the field of cybersecurity, and it is one of the most frequent reasons for cyberattacks.

The entire concept of the trusted zone disappears in Zero Trust. Having accessed the company’s network, you do not gain anything. Every single application checks you and your device separately, thus making an attack from a compromised account much more difficult.

It raises a question about a virtual private network that many companies employ. Is it useless nowadays? Not entirely. A Virtual Private Network performs the same function: providing you with an encrypted connection to the target asset. However, it is crucial to have it if you work with sensitive data using public Wi-Fi from a coffee shop or a hotel network.

What has changed is the role of this tool in your workflow. Previously, you accessed the VPN and gained access to the entire internal network. In Zero Trust, it is merely one of many layers.

You still may continue to use it. Nevertheless, every single application will check you and your device separately. Besides, there are enterprises that implement Zero Trust Network Access solutions. They connect you directly to the necessary application.

How Your Workflow Changes When Adopting Zero Trust

Although many Zero Trust processes occur in the background, there are several changes that you can observe easily.

Multi-factor authentication becomes standard practice. You will be asked to enter a code received by phone, scan a fingerprint, or authenticate with a passkey and password. Passkeys are a type of authentication based on a device unlock mechanism instead of entering passwords or receiving codes via a text message. Most of the large technology companies like Apple, Google, and Microsoft already support this method of authentication, and many businesses are starting to migrate their customers to it due to its robust protection against phishing attacks.

Your device becomes equally important as your username. Special solutions check the operating system’s version on your laptop, whether disk encryption is activated, and whether antivirus software is installed. An outdated device prevents you from using some applications until the updates are performed.

Access is becoming more personal for every employee. You can work with the applications required for completing your tasks. However, you have to request permissions to work with the resources belonging to others. Some applications grant you temporary access that expires after a couple of hours.

Last but not least, your personal phone can also be checked by the company. If you check your work-related mailbox using your phone, the company can ask you to install a corporate management app or configure a corporate profile on it. In most cases, this measure prevents mixing personal and corporate data, so IT specialists are able to wipe out only corporate information in case of losing this device.

However, you are fully justified in asking the IT specialists about this, as the corporate solutions should explicitly inform you what data they access.

Additional verification procedures can happen throughout the day in case you try to open a financial system, sign in from an uncommon place, or perform some actions that require extra security, even if you’ve already signed in that morning.

Reasons for Such Extra Efforts

Surely, nobody wants to receive dozens of notifications on their phone during the workday, but nevertheless, there are some reasons for this.

According to numerous surveys, including Verizon’s Data Breach Investigations Report, phishing and the stealing of passwords are among the most prevalent causes of attacks. Under the traditional network security framework, this would have given an attacker access to everything. However, under the Zero Trust approach, it is not enough for an attacker, and besides, the stolen password would grant access only to a subset of the systems.

Another benefit for you is that in case someone manages to deceive you into disclosing your password, it will reduce the damage you have done. A mistake that previously would cause a serious incident in the company now becomes a minor issue that is easily fixed.

Moreover, Zero Trust gives a chance to implement remote work for the company’s employees. Since access is based on your ID and the state of your device, not your location, remote access becomes feasible for business owners.

Zero Trust also resolves several problems you have. Once Single Sign-On becomes deployed, you will enter passwords much less often than you used to. One single entry grants you access to multiple applications.

Simple Practices That Will Help Implement the Zero Trust Approach More Efficiently

When the technical part of Zero Trust works, there are certain habits that can help increase its effectiveness.

• Do not confirm access attempts if they weren’t initiated by you. Repeat attempts may indicate that someone has your password and is trying to deceive you into confirming such attempts to turn off the notifications.
• Update your device as soon as you can to make sure it is healthy enough to pass all the checks.
• Install an authenticator app provided by your company for authentication purposes.
• Work with your files in corporate applications and not in your personal email or file-sharing service.
• Connect to corporate services via your company’s virtual private network or Zero Trust Network Access.
• Notify your IT department about every suspicious email, prompt, or lost device immediately. Quick action is critical here, and there is no place for embarrassment.
• Specify your reason when asking for access to a certain resource. It improves the probability of approving your request.

Conclusion

The Zero Trust approach might seem somewhat impersonal, but in reality, it says nothing about the relationship of your company to you. It simply realizes the fact that passwords can be stolen, devices are lost, and networks are hacked. All these reasons necessitate individual verification of every access request.

For the average employee, it means additional prompts and device updates, plus customized access levels. Nevertheless, in return, you will have a system that protects you, limits the consequences of your mistakes, and enables you to work wherever you are. Next time your laptop asks you to confirm your identity, you will know that you have a great tool helping you.
