Secure Data Network System (SDNS) Access Control Documents

摘要

The Secure Data Network System (SDNS) implements computer to computer communications security for distributed applications. The internationally accepted Open Systems Interconnection (OSI) computer networking architecture provides the framework for SDNS. SDNS uses the layering principles of OSI to implement secure data transfers between computer nodes of local area and wide area networks. The publication includes three access control documents developed by the National Security Agency as output from the SDNS project. SDN.801 describes the principles and functions underlying the SDNS access control and authentication security services. SDN.802 provides specifications which form a common basis from which devices implementing the access control service will be able to achieve interoperability. The third document in the set, SDN.801 Addendum 1, is an extension of access control information specifications provided in section 5 of SDN.802.
