Security for ONC RPC
Important: This information contains Product-sensitive
Programming Interface and Associated Guidance Information.
Security is an important concern in the provision of ONC RPC support in the CICS® environment, because CICS ONC RPC provides an Open Systems communications interface into CICS.
ONC RPC has its own security methods (called authentication in
RPC) with dedicated fields in the ONC RPC call and reply message headers.
There are three types of RPC authentication:
- UNIX authentication, which is used to transmit the client's UNIX user ID, group ID, and other identification information.
- Data Encryption Standard (DES) authentication, which is not available at ONC RPC Version 3.9, and so cannot be used with CICS ONC RPC.
- Null authentication, which offers no security checking.
This section describes how CICS ONC RPC interacts with the security facilities of ONC RPC and CICS.
