### AI overview

This article explains Zero Trust Architecture as a security model that assumes the network may already be compromised. It contrasts Zero Trust with perimeter security and describes explicit verification, contextual authorization, least privilege, encryption, segmentation, and continuous monitoring. It also distinguishes the broader ZTA model from Zero Trust Network Access (ZTNA).

### Source excerpt

Zero Trust starts from the assumption that the network is already compromised, so every request is authenticated, authorised, and encrypted regardless of where it originates. It rests on explicit verification, least privilege, micro-segmentation, continuous monitoring, and encryption everywhere. It is an architectural direction, not a product you buy.

### AI overview

The article examines how a vehicle immobilizer intended to prevent theft left a ReachNow car immovable on a ferry. It argues that real-world security features involve tradeoffs and can create unexpected problems when products encounter situations their designers did not anticipate.
