Description
This contribution expands Section 8 (Security Considerations) of the cross-domain
authorization specification with comprehensive implementation guidance for
production deployments targeting IETF standardization.
The security considerations provide detailed requirements and best practices across
six operational domains:
Credential Security
and short-lived credentials with re-issuance
Metadata Endpoint Security
Authorization Decision Security
Multi-Agent and Delegation Security
Operational Security
Privacy Considerations
This section builds upon the threat model (PR #146) and provides the normative security
requirements (MUST/SHOULD/MAY) expected in IETF standards-track documents.
Related: Part of the DCR v1 Draft proposal series for the AGNTCY Identity Working Group.
