Description
TSS CICS facilities define the security controls in effect for CICS regions. Failure to code the appropriate values could result in degraded security. This exposure may result in unauthorized access impacting the confidentiality, integrity, and availability of the CICS region, applications, and customer data.

Who does this work

10 NICE work roles and 9 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.

Check Text (C-224737r1146384_chk)

Refer to the following report produced by the z/OS Data Collection: - EXAM.RPT(CICSPROC). Refer to the following reports produced by the TSS Data Collection: - TSSCMDS.RPT(FACLIST) - Preferred report containing all control option values in effect including default values. - TSSCMDS.RPT(TSSPRMFL) - Alternate report containing only control option values explicitly coded at TSS startup. Refer to the CICS Systems Programmer Worksheets filled out from previous vulnerability ZCIC0010. Ensure the following items are in effect for each CICS region's facility. If the following guidance is true, this is not a finding. The TSS CICS facility is defined with the control option values specified in the TOP SECRET INITIALIZATION PARAMETERS FOR CICS REGION Table in the z/OS STIG Addendum. Note: An exception to the STIG is MRO CICS regions in production will use SIGN(M) appropriately. XUSER=YES must be coded in each CICS facility. CICS transactions defined in the BYPASS list are not sensitive transactions.

Fix Text (F-26416r1146384_fix)

Review the TSS control option values for all CICS facilities. Ensure the following items are in effect for each CICS region's facility: The TSS CICS facility is defined with the control option values specified in table - "TOP SECRET INITIALIZATION PARAMETERS FOR CICS REGION", in the zOS STIG Addendum. Note: An exception is MRO CICS regions in production will use SIGN(M) appropriately. XUSER=YES must be coded in each CICS facility. CICS transactions defined in the BYPASS list are not sensitive transactions.
