Zero Trust Architecture

January 20, 2025

Research notes on identity-centric access, micro-segmentation, and continuous verification for cloud-native workloads.

Research summary

Zero Trust replaces perimeter-based trust with continuous verification of identity, device posture, and context for every access decision.

Pillars studied

1. Identity SSO, MFA, least-privilege IAM
2. Network Micro-segmentation, private endpoints
3. Workload mTLS service mesh, signed workloads
4. Data Encryption at rest and in transit, DLP
5. Visibility Centralized logging and UEBA

Standards reference

• NIST SP 800-207 (Zero Trust Architecture)
• CISA Zero Trust Maturity Model

This series documents implementation patterns across AWS, Kubernetes, and hybrid corporate access.
