Sensitive CICS transactions are not protected in accordance with security requirements.

Description
Sensitive CICS transactions offer the ability to circumvent transaction-level controls for accessing resources under CICS. These transactions must be protected so that only authorized users can access them. Unauthorized use can result in the compromise of the confidentiality, integrity, and availability of the operating system or customer data.

Who does this work

17 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-224493r1145202_chk)

Refer to the following reports produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(TCICSTRN). - SENSITVE.RPT(GCICSTRN). Note: If a CICS region is using a site-defined transaction resource class pair, execute a RACF RLIST command against these resource classes. Refer to the CICS Systems Programmer Worksheets filled out from previous vulnerability ZCIC0010. If the following items are in effect for all CICS regions, this is not a finding. Transactions listed in tables CICS CATEGORY 2 CICS AND OTHER PRODUCT TRANSACTIONS and CICS CATEGORY 4 COTS-SUPPLIED SENSITIVE TRANSACTIONS, in the z/OS STIG Addendum, are restricted to authorized personnel. Note: The exception to this is the CEOT and CSGM transactions, which can be made available to all users. Note: The exception to this is the CWBA transaction, can be made available to the CICS Default user. Note: The transactions beginning with "CK" apply to regions running WebSphere MQ. Note: Category 1 transactions are internally restricted to CICS region userids.

Fix Text (F-26164r1145201_fix)

Develop a plan to implement the required changes. Most transactions are protected in groups. An example would be "L2TRANS", which would contain all Category 2 transactions. L2TRANS is defined to RACF as a profile and contains all the Category 2 transactions. An example of how to implement this within RACF is shown here: RDEF GCICSTRN L2TRANS UACC(NONE) OWNER(ADMIN) AUDIT(ALL(READ)) RALT GCICSTRN L2TRANS ADDMEM(CADP CBAM CDBC) Permission to the transaction group can be accomplished with a sample command: PE L2TRANS CL(GCICSTRN) id(<syspaudt>) Note that a refresh is generally needed to the member class. In this case TCICSTRN is the member class for GCICSTRN and a sample refresh command is SETR RACL(TCICSTRN) REFRESH Transactions groups should be defined and permitted in accordance with the CICS Transaction tables listed in the zOS STIG Addendum.
