Information processing systems -- Open Systems Interconnection -- Basic Reference Model -- Part 2: Security Architecture
This standard was last reviewed and confirmed in 2000. Therefore this version remains current.
Provides a general description of security services and related mechanisms, which can be ensured by the Reference Model, and of the positions within the Reference Model where the services and mechanisms may be provided. Extends the field of application of ISO 7498 to cover secure communications between open systems. Adds to the concepts and principles included in ISO 7498 but does not modify them. Is no implementation specification, nor a basis for assessing the conformance of actual implementations.
