IAM Framework
Zero Trust
Zero Trust Architecture (NIST 800-207)
Global
Effective: August 11, 2020
Overview
Zero Trust is a security paradigm that eliminates implicit trust and continuously validates every stage of digital interaction. NIST SP 800-207 provides a framework for implementing Zero Trust Architecture. Key principles include 'never trust, always verify', least privilege access, and assume breach mentality. Zero Trust is increasingly mandated for federal agencies and adopted by enterprises.
IAM Requirements
Identity Verification
- Strong authentication for all users, devices, and workloads
- Continuous verification throughout sessions
- Risk-based authentication adjustments
- Device trust and health verification
Least Privilege Access
- Just-in-time and just-enough access
- Dynamic policy enforcement
- Micro-segmentation of resources
- Application-level access controls
Policy Enforcement
- Centralized policy decision point (PDP)
- Distributed policy enforcement points (PEP)
- Context-aware access decisions
- Real-time policy updates
Continuous Monitoring
- Real-time visibility into all access
- Behavioral analytics for anomaly detection
- Automated threat response
- Comprehensive logging and audit trails
