Description
DFSMS provides data, storage, program, and device management functions for the operating system. Some DFSMS storage administration functions allow a user to obtain a privileged status and effectively bypass all ACP data set and volume controls. Failure to properly protect DFSMS resources may result in unauthorized access. This exposure could compromise the availability and integrity of the operating system environment, system services, and customer data.

NOTE: This PDI applies only if USE_RESOWNER(YES) is specified either explicitly or implicitly in the active IGDSMxx member of SYS1.PARMLIB. If USE_RESOWNER(NO) is specified, this FINDING will be marked NOT APPLICABLE. a) Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(RULES) Provide a list of data set names and/or high-level qualifiers of all DFSMS-controlled data sets. b) Compare the $RESOWNER(resowner) definitions from the ACF2CMDS.RPT(RULES) data set against the PROFILE(DATASET) DIVISION(DFP) definition. c) If the ACF2 data set rules for the SMS controlled data sets have a matching DFP resource owner defined, there is NO FINDING. d) If (c) above is untrue, this is a FINDING.
