Introduction

Trust Governance is the practice of managing the relationship between modern enterprise security services, empowering CISOs to systematically govern risk by leveraging formal verification wherever possible. The Trust Hub enables "governance with proof" by providing mathematical certainty about both Cedar policy correctness and JWT token data integrity throughout the complete authorization trust chain.

trust_governance

This specification focuses on the Trust Hub as a specialized security platform responsible for three critical services: enterprise schema management, enterprise policy management, and federation--the management of trusted domains.

The Trust Hub integrates with GitHub release and PR approval processes to provide governance workflows for both policy and schema changes, ensuring that authorization artifacts receive the same rigor as application code.

Enterprise Schema Management provides centralized capabilities for:

  • Defining entities, attributes, and relationships for Cedar authorization schemas
  • Managing token claim schemas for JWT issuers across the enterprise
  • Validating schema compatibility and detecting conflicts between different schema versions
  • Coordinating schema evolution across multiple applications and policy stores
  • Providing migration paths and backward compatibility analysis for schema changes

Enterprise Policy Management delivers comprehensive policy governance including:

  • Cedar policy authoring tools with syntax validation and semantic analysis
  • Formal verification capabilities to mathematically prove policy soundness and correctness
  • Cross-policy store analysis to identify conflicts, redundancies, and coverage gaps
  • Policy utilization analytics based on real-time authorization data from connected systems
  • Policy lifecycle management with approval workflows, versioning, and deprecation processes
  • Integration with Cedar Analysis Toolkit for advanced policy verification (never-errors, equivalence, disjointness)
  • Integration with Amazon Verified Permissions and Gluu Flex for policy usage analytics

Trusted Entity Management encompasses the governance of trust relationships including:

  • JWT issuer configuration and trust relationship management
  • Classification
  • Token validation rules, revocation checking, and cryptographic verification
  • OpenID Federation entity statement publication and validation
  • Trust chain management for complex federation scenarios

The Trust Hub addresses the gap between traditional identity management tools and the specialized requirements of agentic governance, providing organizations with the capabilities needed to implement authorization with mathematical proof rather than just compliance documentation.
