| Security architecture for Open Systems Interconnection for CCITT applications |
 |
Recommendation ITU-T X.800:
a) provides a general description of security services and related mechanisms, which may be provided by the Reference Model; and
b) defines the positions within the Reference Model where the services and mechanisms may be provided.
This Recommendation extends the field of application of Recommendation X.200, to cover secure communications between open systems.
Basic security services and mechanisms and their appropriate placement have been identified for all layers of the Reference Model. In addition, the architectural relationships of the security services and mechanisms to the Reference Model have been identified. Additional security measures may be needed in end systems, installations and organizations. These measures apply in various application contexts. The definition of security services needed to support such additional security measures is outside the scope of the Recommendation.
