Zero Trust Network Implementation

Zero Trust Network Implementation

Zero Trust Principles

Zero Trust assumes breach and verifies every access request regardless of location. Core principles include verify explicitly, use least privilege, and assume breach. Zero Trust eliminates implicit trust based on network location.

Zero Trust Network

Identity-Centric Security

Build Zero Trust on strong identity including multi-factor authentication, continuous authentication, device identity, application identity, and context-based access decisions. Identity becomes new perimeter replacing network location.

Microsegmentation

Implement granular segmentation isolating workloads, enforce least privilege network access, create security zones, and apply identity-based policies. Microsegmentation prevents lateral movement limiting breach impact.

Continuous Verification

Continuously verify user and device posture, monitor behaviors for anomalies, re-authenticate based on risk, validate encryption and compliance, and adapt access based on real-time risk assessment.

Implementation Phases

Phase 1: Visualize (map flows and dependencies), Phase 2: Mitigate (segment and protect), Phase 3: Optimize (automate and improve). Start with critical assets, expand gradually, and measure progress with zero trust maturity models.
