Zero Trust, or Zero Trust Access, is the term applied to the strategy that assumes you cannot trust the individual or device until verified.  The good guys, the bad guys, and all devices are the same and should not be trusted automatically. Proof of trust is verified with credentials.

The term was first coined in 1994 by Stephan Paul Marsh at the University of Stirling as part of his doctoral thesis focused on trust. Over the next ten years, it became part of the tech vernacular in defining the perimeter of security access.

Three Principles

While implementing a zero-trust strategy can happen differently, a zero-trust architecture will always have similar elements.

  • User/Application authentication – grouped since some actions are automated
  • Device authentication – consideration of access scenarios, will access be granted through a mobile phone, IoT device, different locations, etc
  • Trust layers – evaluation of access based on application layers rather than overall network access
  • Interaction – a way of duplicating verification through interactivity

These principles are modeled together on the “never trust, always verify” foundation. And that means they need to be verified even if connected to a corporate LAN. The complexity of today’s technology landscape means we cannot operate on any assumptions. Verification or validation should not be automatic because a device or login exists on a network.
