Vulnerability discussion

JES2 system commands are used to control JES2 resources and the operating system environment. Failure to properly control access to JES2 system commands could result in unauthorized personnel issuing sensitive JES2 commands. This exposure may threaten the integrity and availability of the operating system environment, and compromise the confidentiality of customer data.

a) Refer to the following reports produced by the ACF2 Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(OPERCMDS) - ACF2CMDS.RPT(RESOURCE) – Alternate report - ACF2CMDS.RPT(ACFGSO) NOTE: Review the ACFGSO report. If CLASMAP defines OPERCMDS as anything other than TYPE(OPR), replace OPR below with the appropriate three letters. Refer to the following report produced by the z/OS Data Collection: - EXAM.RPT(SUBSYS) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZJES0051) b) Review resource rules for TYPE(OPR). c) If the JES2.- resource is defined to the OPERCMDS class, there is NO FINDING. NOTE: JES2 is typically the name of the JES2 subsystem. Refer to the SUBSYS report and locate the entry with the description of PRIMARY JOB ENTRY SUBSYSTEM. The SUBSYSTEM NAME of this entry is the name of the JES2 subsystem. d) If the JES2.- resource is NOT defined to the OPERCMDS class, this is a FINDING.

Fix text

The IAO will ensure that the JES2.* resource is defined to the OPERCMDS class with a default of no access and all access is logged. If CLASMAP defines OPERCMDS as anything other than TYPE(OPR), replace OPR below with the appropriate three letters. Review resource rules for TYPE(OPR). Ensure the JES2.- resource is defined to the OPERCMDS class. Example: SHOW CLASMAP $KEY(JES2) TYPE(OPR) - UID(*) PREVENT

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.
