a) Refer to the following reports produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(CATURPT) - User Catalogs Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ACP00135) ___ The ACP data set rules for System Catalogs allow inappropriate access. ___ The ACP data set rules for User Catalogs do not restrict ALTER access / ALTER and SCRATCH (TSS) to only z/OS systems programming personnel. ___ The ACP data set rules for User Catalogs do not specify that all (i.e., failures and successes) ALTER access will be logged. b) If all of the above are untrue, there is NO FINDING. c) If any of the above is true, this is a FINDING.

Fix text

Review access authorization to critical system files. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes as required to protect USER CATALOGS. The IAO will ensure that allocate access to USER CATALOGS are limited to system programmers only and all allocate access is logged.

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.
