Free preview: Verify explicitly, least privilege, assume breach — Zero Trust Security Architecture

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.

This is one lesson from Zero Trust Security Architecture.
