Discussion
JES2 system commands are used to control JES2 resources and the operating system environment. Failure to properly control access to JES2 system commands could result in unauthorized personnel issuing sensitive JES2 commands. This exposure may threaten the integrity and availability of the operating system environment, and compromise the confidentiality of customer data.

The IAO will ensure that the JES2.* resource is defined to the OPERCMDS class with a default of no access and all access is logged. If CLASMAP defines OPERCMDS as anything other than TYPE(OPR), replace OPR below with the appropriate three letters. Review resource rules for TYPE(OPR). Ensure the JES2.- resource is defined to the OPERCMDS class. Example: SHOW CLASMAP $KEY(JES2) TYPE(OPR) - UID(*) PREVENT
