Security Advanced

What is Zero Trust?

A security model that requires strict identity verification for every user and device, regardless of their network location.

Zero Trust follows the principle "never trust, always verify." Unlike traditional perimeter-based security, Zero Trust assumes threats exist both inside and outside the network. Every access request is fully authenticated, authorized, and encrypted.

Key principles include least-privilege access, micro-segmentation, continuous verification, and assuming breach. Implementation involves identity management, network segmentation, endpoint security, and comprehensive monitoring.
