Zero Trust Architecture: Principles, Identity-Based Access, Microsegmentation, and Implementation

Zero Trust Architecture#

Zero trust means no implicit trust. A request from inside the corporate network is treated with the same suspicion as a request from the public internet. Every request must prove who it is, what it is allowed to do, and that it is coming from a healthy device or service — regardless of network location.

This is not a product you buy. It is an architectural approach that requires changes to authentication, authorization, network design, and monitoring.
