Vulnerability discussion

Ensure that RACF data set rules for all VTAM system data sets restrict access to only network systems programming staff. These data sets include libraries containing VTAM load modules and exit routines, and VTAM start options and definition statements.Failure to properly control VTAM datasets could potentially compromise the network operations.

Check content

a) Create a list of data set names containing all VTAM start options, configuration lists, network resource definitions, commands, procedures, exit routines, all SMP/E TLIBs, and all SMP/E DLIBs used for installation and in development/production VTAM environments. Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(VTAMRPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZVTM0018) b) Ensure that RACF data set rules for all VTAM system data sets restrict access to only network systems programming staff. These data sets include libraries containing VTAM load modules and exit routines, and VTAM start options and definition statements. c) If (b) above is true, there is NO FINDING. d) If (b) above is untrue, this is a FINDING.

Data Set Controls Ensure that RACF data set rules for all VTAM system data sets restrict access to only network systems programming staff. These data sets include libraries containing VTAM load modules and exit routines, and VTAM start options and definition statements. The following sample RACF commands show proper definitions/permissions for VTAM datasets: AD 'SYS1.VTAM*.**' UACC(NONE) OWNER(SYS1) - AUDIT(SUCCESS(UPDATE) FAILURES(READ)) - DATA('IBM VTAM DS PROFILE: REF SRR PDI ZVTM0018') PE 'SYS1.VTAM.**' ID() ACC(A) AD 'SYS1.VTAMLIB.**' UACC(NONE) OWNER(SYS1) - AUDIT(SUCCESS(UPDATE) FAILURES(READ)) - DATA('IBM VTAM APF DS PROFILE: REF SRR PDI ZVTM0018') PE 'SYS1.VTAMLIB.**' ID() ACC(A) AD 'SYS1.VTAM.SISTCLIB.**' UACC(NONE) OWNER(SYS1) - AUDIT(SUCCESS(UPDATE) FAILURES(READ)) - DATA('IBM VTAM APF DS PROFILE: REF SRR PDI ZVTM0018') PE 'SYS1.VTAM.SISTCLIB.**' ID() ACC(A) AD 'SYS3.VTAM.**' UACC(NONE) OWNER(SYS3) - AUDIT(SUCCESS(UPDATE) FAILURES(READ)) - DATA('VTAM CUSTOMIZED DS: REF SRR PDI ZVTM0018') PE 'SYS3.VTAM.**' ID() ACC(A) AD 'SYS3.VTAMLIB.**' UACC(NONE) OWNER(SYS3) - AUDIT(SUCCESS(UPDATE) FAILURES(READ)) - DATA('IBM VTAM APF DS PROFILE: REF SRR PDI ZVTM0018') PE 'SYS3.VTAMLIB.**' ID() ACC(A) SETR GENERIC(DATASET) REFRESH

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.
