Title
IBM CICS Transaction Server SPI command resources must be properly defined and protected. (Cat II impact)
Discussion
IBM CICS Transaction Server can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to product resources could result in the compromise of the operating system environment, and compromise the confidentiality of customer data. Many utilities assign resource controls that can be granted to system programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.

Refer to the following report produced by the ACF2 Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(XCMD) - ACF2CMDS.RPT(RESOURCE) - Alternate report Automated Analysis: Refer to the following report produced by the ACF2 Data Collection Checklist: - PDI (ZCIC0021) Ensure that all IBM CICS Transaction Server SPI command resources defined in the IBM CICS-RACF Security Guide are properly protected according to the requirements specified in the site security plan, use CICS SPI Resources table in the zOS STIG Addendum as a guide. If the following guidance is true, this is not a finding. The ACF2 resources and/or generic equivalent as designated in the above table are defined with a default access of PREVENT. The ACF2 resource access authorizations restrict access to the appropriate personnel as designated in the above table.
Fix Text
Ensure that the IBM CICS Transaction Server SPI command resources defined in the IBM CICS-RACF Security Guide access is in accordance with those outlined in the site security plan use CICS SPI Resources table in the zOS STIG Addendum as a guide. These tables list the resources and access requirements for IBM CICS Transaction Server; ensure the following guidelines are followed: The ACF2 resources and/or generic equivalent as designated in the above table are defined with a default access of PREVENT. The ACF2 resource access authorizations restrict access to the appropriate personnel as designated in the above table. The following commands are provided as a sample for implementing resource controls: $KEY(ASSOCIATION) TYPE(XCD) - UID(CICSAUDT) SERVICE(READ) ALLOW - UID(CICUAUDT) SERVICE(READ) ALLOW - UID(SYSCAUDT) SERVICE(READ) ALLOW - UID(*) PREVENT
