IDMS regions (central versions) Userids/ACIDs are not defined to the PROPCNTL resource class.

Description
Improperly defined IDMS central versions (CVs) have the potential to bypass security controls and obtain unauthorized access to system resources. This could potentially compromise the confidentiality, integrity, and availability of the operating system, ACP, and customer data.

a) Refer to the following report produced by the RACF Data Collection: - RACFCMDS.RPT(PROPCNTL) Refer to the IDMS Worksheet in the z/OS STIG Adendum and copy it and fill out the information for each IDMS CV running on this LPAR. b) Ensure the following items are in effect: - Userids of IDMS CVs that run as a started tasks have a profile defined to the PROPCNTL resource class. - Userids of IDMS CVs that run as a batch jobs have a profile defined to the PROPCNTL resource class. c) If both items in (b) are true, there is NO FINDING. d) If either item in (b) is untrue, this is a FINDING.

Fix Text (F-18531r1_fix)
Propagation control must be implemented for each region/CV to ensure that the CV's userid is not propagated to batch jobs submitted by that region. This is done by defining in the PROPCNTL class profiles whose names match those of each region (CV) assigned userid. The following is an example of the steps necessary to ensure that propagation control is activated for the regions. Do the following for each region/CV userid: • Define a profile to the PROPCNTL class: RDEFINE PROPCNTL UACC(NONE) OWNER(ADMIN) AUDIT(ALL(READ)) For example, if the resource name (IDMS region's userid) is IDMSD, then the command would be as follows: RDEFINE PROPCNTL IDMSD UACC(NONE) OWNER(ADMIN) AUDIT(ALL(READ)) • Ensure that the PROPCNTL class is active: SETROPTS CLASSACT(PROPCNTL) • Ensure that SETROPTS RACLIST processing is active for the PROPCNTL class: SETROPTS RACLIST(PROPCNTL)
