Vulnerability discussion

CLASSACT specifies those classes defined by entries in the class descriptor table for which RACF checking is to be ACTIVE.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.

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 DATASET, USER, GROUP, and TEMPDSN resource classes are ACTIVE this is not a finding. Note: At minimum, the DATASET, USER, GROUP, and TEMPDSN classes should be ACTIVE.

Fix text

The IAO will ensure that SETROPTS CLASSACT has been specified, at minimum, for the DATASET, USER, GROUP, and TEMPDSN resource classes. 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(DATASET, USER, GROUP, TEMPDSN) It is not recommended to perform a SETR CLASSACT(*).

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
