Using the MODIFY SECURITY and the DISPLAY ID commands, you can display or change the message authentication specifications for an LU.

MODIFY SECURITY

Increase the security specifications as defined in the applications' resource definition. Any change you make must increase the level of the message authentication required for the application.

DISPLAY ID

Display the current security data for the application. The DISPLAY ID has session status modifiers to show what a given session level is using for the level of encryption (DES = D or Triple-DES = T) encryption. See z/OS Communications Server: IP and SNA Codes.
