Title
The CLASSACT SETROPTS must be specified for the TEMPDSN Class. (Cat II impact)
Discussion
CLASSACT specifies those classes defined by entries in the class descriptor table for which RACF checking is to be ACTIVE. DATASET, USER, and GROUP are active by default and cannot be activated or deactivated. The system-wide options control the default settings for determining how the Access Control Program (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.
Check Content
Refer to the following report produced by the RACF Data Collection: - RACFCMDS.RPT(SETROPTS) Automated Analysis Refer to the following report produced by the RACF Data Collection: - PDI(RACF0270) If the TEMPDSN resource class is ACTIVE, this is not a finding. Note: At minimum, the TEMPDSN class should be ACTIVE.
Fix Text
The IAO will ensure that SETROPTS CLASSACT has been specified, at minimum, for the TEMPDSN resource class. 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. IBM recommends activating the classes important to your installation. At minimum the command: SETR CLASSACT(TEMPDSN) It is not recommended to perform a SETR CLASSACT(*).
