SV-226r1_rule Propagation control is not in use, thus allowing ACID inheritance.

Vulnerability discussion

Batch jobs should have associated ACIDs identified to the system to designate the resources available to the job. Propagation control is used to secure special ACIDs that are not subject to automatic propagation of batch jobs. If propagation control is not used, the ACIDs authority of the subsystem is inherited. Failure to control batch job propagation could compromise the operating system environment, ACP, and customer data.

Refer to the following reports produced by the TSS Data Collection: - TSSCMDS.RPT(FACLIST) - TSSCMDS.RPT(@ACIDS) - TSSCMDS.RPT(WHOOPROP) Automated Analysis Refer to the following report produced by the TSS Data Collection: - PDI(TSS0760) Review the FACLIST report to determine which Facilities are defined with both the MULTIUSER and ASUBM attributes. If no Facility is defined with both the MULTIUSER and ASUBM attributes further analysis is not needed. For each Facility with MULTIUSER and ASUBM attribute, review the @ACIDS report to determine which ACID(s) has (have) the following: 1) A Master Facility of the Facility with MULTIUSER and ASUBM attribute, and, 2) The Facility of BATCH If no ACID is defined with both the characteristics mentioned in above, further analysis is not needed. For each ACID that has the Master Facility of the Facility with MULTIUSER and ASUBM attribute and has the Facility of BATCH, they will be defined to the PROPCNTL resource class.

Fix text

Ensure an associated ACID exists for all batch jobs and propagation control is being used. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes as required. The following Example shows the CONTROL-M STC ACID being owned to the PROPCNTL resource class: TSS ADD(deptacid) PROPCNTL(control-m-acid)
