Description
CL/SuperSession configuration/parameters control the security and operational characteristics of products. If these parameter values are improperly specified, security and operational controls may be weakened. This exposure may threaten the availability of the product applications and compromise the confidentiality of customer data.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Version 3 of CL/SuperSession Review the member KLKINNAM in the TLVPARM DD statement concatenation of the CL/SuperSession STC procedure. (This member is located in SYS3.OMEGAMON.qualifier.RLSPARM.) Version 2 of CL/SuperSession Review the member KLVINNAM in the TLVPARM DD statement concatenation of the CL/SuperSession STC procedure. (This member is located in SYS3.OMEGAMON.qualifier.RLSPARM.) Automated Analysis Refer to the following report produced by the z/OS Data Collection: - PDI(ZCLS0042). If one of the following configuration settings is specified for each control point defined in the KLKINNAM member for version 3 of CL/SuperSession or KLVINNAM member for version 2 of CL/SuperSession, this is not a finding. DEFAULT DSNAME(SYS3.OMEGAMON.qualifier.RLSNAM) - RACF - CLASSES=APPCLASS - NODB EXIT=KLVRACVR (The following is for z/OS CAC logon processing) DEFAULT DSNAME(SYS3.OMEGAMON.qualifier.RLSNAM) - SAF - (RACF is also acceptable) CLASSES=APPCLASS - NODB - EXIT=KLSNFPTX

Fix Text (F-26133r1041311_fix)

Ensure that the parameter options for member KLKINNAM for version 3 of CL/Supersession or KLVINNAM for version 2 of CL/SuperSession are coded to the below specifications. (Note: The data set identified below is an example of a possible installation. The actual data set is determined when the product is actually installed on a system through the product's installation guide and can be site specific.) Review the member KLKINNAM or KLVINNAM in the TLVPARM DD statement concatenation of the CL/SuperSession STC procedure. (This member is located in SYS3.OMEGAMON.qualifier.RLSPARM.) Ensure all session manager security parameters and control options are in compliance according to the following: DEFAULT DSNAME(SYS3.OMEGAMON.qualifier.RLSNAM) - RACF - CLASSES=APPCLASS - NODB EXIT=KLVRACVR (The following is for z/OS CAC logon processing) DEFAULT DSNAME(SYS3.OMEGAMON.qualifier.RLSNAM) - SAF - (RACF is also acceptable) CLASSES=APPCLASS - NODB - EXIT=KLSNFPTX
