Title

SMS Program Resources must be properly defined and protected. (Cat II impact)

Discussion

DFSMS provides data, storage, program, and device management functions for the operating system. Some DFSMS storage administration functions allow a user to obtain a privileged status and effectively bypass all ACP data set and volume controls. Failure to properly protect DFSMS resources may result in unauthorized access. This exposure could compromise the availability and integrity of the operating system environment, system services, and customer data.

The IAO will work with the systems programmer to verify that the following are properly specified in the ACP. (Note: The resource type, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource type, resources, and/or resource prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.) Use SMS Program Resources table in the zOS STIG Addendum. This table lists the resources, access requirements for SMS Program Resources. Ensure the guidelines for the resource type, resources, and/or generic equivalent specified in the z/OS STIG Addendum are followed. The RACF resources as designated in the above table are defined with a default access of NONE. The RACF resource access authorizations restrict access to the appropriate personnel as designated in the above table. The RACF resource rules for the resources designated in the above table specify UACC(NONE) and NOWARNING. The following commands are provided as a sample for implementing resource controls: RDEF PROGRAM ACBFUTO2 ADDMEM('SYS1.DSF.DGTLLIB'//NOPADCHK) - DATA('ADDED PER SRR PDI ZSMS0012 ') - AUDIT(FAILURE(READ)) UACC(NONE) OWNER(ADMIN) PERMIT ACBFUTO2 CLASS(PROGRAM) ID(audtaudt) PERMIT ACBFUTO2 CLASS(PROGRAM) ID(dasdaudt) PERMIT ACBFUTO2 CLASS(PROGRAM) ID(secaaudt) PERMIT ACBFUTO2 CLASS(PROGRAM) ID(syspaudt) PERMIT ACBFUTO2 CLASS(PROGRAM) ID(tstcaudt)
