From z/OS ACF2 STIG

Part of ZIDM0030

Associated with IA controls: DCCS-1, DCCS-2

SV-47r1_rule IDMS regions (central versions) STC and or batch jobs are not defined in accordance with the proper security requirements.

Vulnerability discussion

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.

Check content

a) Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(LOGONIDS) 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 for IDMS CV logonids: - A unique logonid is associated with each IDMS CV. - Logonids of IDMS CVs that run as a started task, have the following attributes: MUSASS, NO-SMC, JOBFROM, MUSUPDT, STC - Logonids of IDMS CVs that run as a batch job have the following attributes: MUSASS, NO-SMC, JOBFROM, MUSUPDT, RESTRICT, PGM(xxxxxxxx), SUBAUTH c) If all items in (b) are true, there is NO FINDING. d) If any item in (b) is untrue, this is a FINDING.

Fix text

The IAO will ensure that IDMS regions (central versions) are defined with a unique userid and is properly defined to the ACP. Ensure the following items are in effect for IDMS CV logonids: - A unique logonid is associated with each IDMS CV. - Logonids of IDMS CVs that run as a started task, have the following attributes: MUSASS, NO-SMC, JOBFROM, MUSUPDT, STC Example: INSERT IDMSCV NAME(STC, IDMSCV) MUSASS NO-SMC JOBFROM MUSUPDT STC - Logonids of IDMS CVs that run as a batch job have the following attributes: MUSASS, NO-SMC, JOBFROM, MUSUPDT, RESTRICT, PGM(xxxxxxxx), SUBAUTH Example: INSERT IDMSBAT NAME(STC, IDMS BATCH) MUSASS NO-SMC JOBFROM MUSUPDT RESTRICT PGM(xxxxxxxx) SUBAUTH

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.
