What Is Zero Trust?
Zero Trust Access
Zero Trust, or Zero Trust Access, is the term applied to the strategy which assumes that 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 that focused on trust. Over the next ten years, it became part of the tech vernacular as it relates to defining the perimeter of security access.
