ITU-T X.805 — Security Architecture for End-to-End Communications
ITU-T Recommendation X.805 (2003, still actively referenced) defines a security architecture for systems providing end-to-end communications. It uses a layered approach across three security layers (infrastructure, services, applications), three security planes (management, control, end-user), and eight security dimensions (access control, authentication, non-repudiation, data confidentiality, communication security, data integrity, availability, privacy).
