Security in ONC RPC

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.
