Zero Trust Architecture

Status: draft · Confidence: low (0.43) · Basis: verified_sources

Quality notes: generic_source_homepage, no_verified_sources, partial_source_verification

## TL;DR

Zero Trust is a security model that assumes no implicit trust — verify every access request regardless of network location (internal or external). Core principles: never trust, always verify; least privilege access; assume breach. Mandated by US Executive Order 14028 (2021) for federal agencies.

## Core Explanation

Key components: microsegmentation (network isolation), identity-aware proxies, continuous authentication, encryption everywhere. Replaces the castle-and-moat model (trusted internal network, untrusted external). Implementation frameworks: Google BeyondCorp (origin of Zero Trust, 2014), NIST SP 800-207. ZTNA (Zero Trust Network Access) replaces traditional VPNs.
