Free preview lesson · Zero Trust Security Architecture · Module 1: Zero Trust principles
Verify explicitly, least privilege, assume breach
Zero Trust is not a product. It is a set of three principles that change how every access decision is made.
Verify explicitly
Every request is authenticated and authorised using identity, device and context, not network location.
Least privilege
Users and services get only the access they need, for only as long as they need it.
Assume breach
Design as if an attacker is already inside: limit blast radius and monitor continuously.
Common pitfall
Treating Zero Trust as a single purchase rather than a programme.
Action step
List three systems you use and note who can access each one today and why.
