Title

The REALDSN SETROPTS value specified is improperly set. (Cat III impact)

Discussion

REALDSN specifies that RACF is to record, in any SMF log records and operator messages, the real data set name (not the naming-conventions name) used on the data set commands and during resource access checking and resource definition. The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during migration process or contingency plan activation.
