Zero Trust Security

Stay protected and productive with the Zero Trust approach to cybersecurity

In a world where we work at any time, from any location and on a wide range of devices, companies are discovering the limitations of traditional security models.

Perimeter-based security, VPN’s and verified workstations are no longer enough to handle an increasingly aggressive threat landscape and modern ways of working.

This is especially true for highly regulated verticals like life sciences, finance, energy and public sector.

We need a different approach to cybersecurity, which is more flexible, easier to automate and where communication and data access can be easily verified and controlled.

We need Zero Trust.

What is Zero Trust?

Zero Trust is an overall approach to cyber security, a design philosophy and way of thinking rather than a specific recipe or product. At its core, Zero Trust is the embodiment of the old proverb “trust is good, but control is better”.

Contrary to what the name implies, Zero Trust does not equal a total absence of trust. Instead, Zero Trust means you establish and verify the trust needed before giving access to data or resources.. All access is regulated based on specific parameters actively designated for each individual user.

In essence, users establish trust every single time they attempt to access data or systems. The zero in Zero Trust represents the baseline level of trust before the user verifies their identity and access privileges.

This may sound cumbersome and counter-productive, but done correctly, Zero Trust is easy and intuitive to work with and can make life easier for the users. And it provides organizations with much greater control of who has access to their data and critical systems.

Manage identity and access (IAM)

With Zero Trust, security is centered around user identity. This means that being able to verify identity and regulate user roles through Identity and Access Management (IAM) is essential. Most modern IAM systems provide all the functionalities needed for Zero Trust, but good governance and clearly defined processes and procedures are equally important.

This does not only apply to human users. Today, a significant percentage of all digital processes are carried out by robots and automated systems interacting with each other. Just like human users, these digital entities need to be evaluated and validated.

In fact, since robots have highly predictable work patterns, more factors can be taken into consideration. For example, if a robot designed to perform credit evaluations suddenly attempts to access R&D data or personnel files, access would be denied, and alerts triggered.

Keep your networks secure

With Zero Trust, you can regulate how your systems communicate at the software level. By defining approved protocols and ports, you are able to set up automated surveillance which monitors your network for unauthorized traffic and pick up on suspicious activity before user identity verification comes into play.

Even if your data is encrypted, automated network detection and response will still be able to identify unusual patterns and shut down access attempts that deviate from the expected.

A greater degree of network segmentation and use of isolated subnets is a natural consequence of Zero Trust. This includes access to legacy systems, where individual risk assessments should determine the best strategy for ensuring security.

Zero Trust and Cloud

With the increasing use of cloud infrastructure and applications, a Zero Trust approach is just as relevant in the cloud as it is on premise. All major Public and Private Cloud vendors have numerous options for applying Zero Trust security to your cloud-based data and SaaS applications.

But just as it is the case with on-premises, applying the Zero Trust approach using these tools correctly is far from trivial. Successful Zero Trust security in the cloud requires a disciplined approach with comprehensive risk assessments and careful consideration of how critical the data or system is. For example, should users be able to access a cloud service directly or should traffic go through your company network?
