The OPERCMDS resource class is not active. (Cat II impact)

Discussion

z/OS system commands provide a method of controlling the operating environment. Failure to properly control access to z/OS system commands could result in unauthorized personnel issuing sensitive system commands. This exposure may threaten the integrity and availability of the operating system environment, and compromise the confidentiality of customer data.

Fix Text

The IAO will ensure that the OPERCMDS class is active. Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option as specified in the example below: The RACF Command SETR LIST will show the status of RACF Controls including a list of ACTIVE classes. (1) The OPERCMDS Class is activated with the command SETR CLASSACT(OPERCMDS). (2) Generic profiles and commands should also be enabled with the command SETR GENERIC(OPERCMDS) GENCMD(OPERCMDS). (3) IBM recommends RACLISTing the OPERCMDS Class which is accomplished with the command SETR RACL(OPERCMDS). Refer to ACP00282 for information on content of the OPERCMDS class.
