Fix Recommendation

The ISSO will work with the systems programmer to verify that the following are properly specified in the Access Control Program (ACP).

(Note: The resources and/or resource prefixes identified below are examples of a possible installation. The actual 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.)

Ensure that all ROSCOE resources and/or generic equivalent are properly protected according to the requirements specified in CA ROSCOE Resources table in the z/OS STIG Addendum.

Use CA ROSCOE Resources table in the z/OS STIG Addendum. This table lists the resources, access requirements, and logging requirements for ROSCOE ensure the following guidelines are followed:

The RACF resource access authorizations restrict access to the appropriate personnel.

The RACF resource logging is correctly specified.

The RACF resource access authorizations specify UACC(NONE) and NOWARNING.

The following commands are provided as a sample for implementing resource controls:

RDEFINE RO@RES rosid.** UACC(NONE) OWNER(ADMIN) AUDIT(FAILURE(READ))
RDEFINE RO@RES rosid.ROSCMD.** UACC(NONE) OWNER(ADMIN) AUDIT(FAILURE(READ))
RDEFINE RO@RES rosid.ROSCMD.MONITOR.** UACC(NONE) OWNER(ADMIN) AUDIT(FAILURE(READ))
RDEFINE RO@RES rosid.ROSCMD.ETSO UACC(NONE) OWNER(ADMIN) AUDIT(FAILURE(READ))
RDEFINE RO@RES rosid.ROSCMD.MONITOR.AMS UACC(NONE) OWNER(ADMIN) AUDIT(FAILURE(READ))

PE rosid.ROSCMD.ETSO CLASS(RO@RES) ID(*) ACCESS(READ)
PE rosid.ROSCMD.MONITOR.- CLASS(RO@RES) ID(syspaudt) ACCESS(ALTER)
PE rosid.ROSCMD.MONITOR.AMS CLASS(RO@RES) ID(syspaudt) ACCESS(ALTER)
PE rosid.ROSCMD.MONITOR.AMS CLASS(RO@RES) ID(*) ACCESS(READ)
PE rosid.ROSCMD.- CLASS(RO@RES) ID(syspaudt) ACCESS(ALTER)

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZROS0020).

Verify all ROSCOE resources and/or generic equivalent are properly protected according to the requirements specified in the CA ROSCOE Resources table in the z/OS STIG Addendum. Note: Wherever an access or user group is missing, use the Site Security Plan (SSP) to determine access and/or user group. If the following guidance is true, this is not a finding.

The RACF resource access authorizations restrict access to the appropriate personnel.

The RACF resource logging is correctly specified.

The RACF resource access authorizations are defined with UACC(NONE) and NOWARNING.
