Description
CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. Improperly defined or controlled CICS userids (i.e., region, default, and terminal users) may provide an exposure and vulnerability within the CICS environment. This could result in the compromise of the confidentiality, integrity, and availability of the CICS region, applications, and customer data.

Who does this work

7 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.

Check Text (C-224305r1141384_chk)

Refer to the following report produced by the z/OS Data Collection: - EXAM.RPT(CICSPROC). Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(LOGONIDS). Refer to the CICS Systems Programmer Worksheets filled out from previous vulnerability ZCIC0010. Verify the following items are in effect for each CICS region logonid. If the following guidance is true, this is not a finding. A unique logonid is associated with the CICS region. The CICS region logonid has the STC, ACF2CICS, MUSASS, and NO-SMC attributes specified. Note: The ACF2CICS privilege will be restricted to CICS region logonids only. If CICS region submits jobs on behalf of its users, the JOBFROM attribute is specified. If CICS region has a requirement to update information in the ACF2 database, the MUSUPDT attribute is specified. Not granted the ACF2 NON-CNCL privilege. No access to interactive online facilities (e.g., TSO) other than CICS.

Fix Text (F-25970r1141383_fix)

The ISSO will ensure that each CICS region is associated with a unique userid and that userid is properly defined. Review all CICS region, default, and end-user userids to ensure they are defined and controlled as required. Ensure that the following is defined for each CICS region: A unique userid is defined. Use the ACF2 insert command to accomplish this. A sample command is provided here: INSERT <cicsregionid> NAME('STC, CICS Region') JOBFROM MUSASS NO-SMC STC ACF2CICS
