UACC and ID(*) in RACF

If you work with mainframes, you are probably familiar with UACC (universal access) and ID(*). Many people believe that UACC and ID(*) represent the same thing. This is not true. They are slightly different and you need to take the difference in consideration when planning your RACF security environment.

Access Authority Description
ID(*) Defines the default access level to all RACF defined users
UACC (Universal Access) Defines the default access level to all users and groups defined or not in RACF.  UACC applies to any user including those defined through UADS.
