Overview of access control support

Communications Server is a resource manager that provides access control support over many of its services.

This can be a powerful tool to prevent unwanted usage of communications services. At times, it might also prevent intended usage. TCP/IP uses Security Access Facility (SAF) interfaces to ask your installed security server access control questions.
Note: The examples and terminology in this topic assume you are using RACF®. However, you can use any SAF-conforming security server.
