What Is Zero Trust?

The term ‘Zero Trust’ was first coined by John Kindervag in 2010, building off a concept put forward by David Lacey at the Jericho Forum, an international group founded in 2004 that worked to promote deperimeterization.

Deperimeterization means to “protect an organisation’s systems and data on multiple levels, by using a mixture of encryption, secure computer protocols, secure computer systems and data-level authentication” (Wikipedia). Our Managing Security Consultant, Colin Robbins, has been discussing deperimeterization for over 5 years.

Over the past few years, the world has seen a period of digital transformation. The increasingly popular use of Cloud-based solutions and remote working are eroding traditional security boundaries. Network architecture is changing, as static work environments are being phased out in favour of letting employees work from any location at any time.

In this new world, the role of local networks and Intranet changes, it no longer poses a significant security boundary, as business data is now outside of that network on cloud services. Thus, the priorities of the local network have shifted to providing access, not security. The need for security has not been diminished and a replacement solution must be found – this is where Zero Trust fits in – it helps provide confidence that your users and devices are appropriately trusted to be able to access your (on premise and cloud-based) services.

Zero Trust Architecture – NCSC

Zero Trust is a term being (mis)used by some product vendors, to push their unique angle on it. To cut through this, the NCSC, along with techUK, are working toward a non-partisan view of the base principles.

As part of this, the NCSC has developed a series of principles that will help people understand and migrate to a zero trust architecture. These principles are still in development and they have recently reduced the 10 alpha principles down to 8 beta principles.
