Fix Recommendation

Ensure that the CA 1 function and password resource access is in accordance with those outlined in CA 1 Function and Password Resources table in the zOS STIG Addendum.

Use CA 1 Function and Password Resources and CA 1 Function and Password Resources for TSS tables in the zOS STIG Addendum. These tables list the resources, access requirements, and the resource class for CA 1 Function and Password Resources; ensure the following guidelines are followed:

The TSS resources and/or generic equivalent as designated in the above table are owned or DEFPROT is specified for the resource class.

The TSS resource access authorizations restrict access to the appropriate personnel as designated in the above table.

The TSS resource logging is specified as designated in the above table.

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

TSS ADD(dept-acid) CATAPE(BLPRES)
TSS PERMIT(tapeaudt) CATAPE(BLPRES) ACCESS(UPDATE) ACTION(AUDIT)
TSS PERMIT(syspaudt) CATAPE(BLPRES) ACCESS(UPDATE) ACTION(AUDIT)

- SENSITVE.RPT(WHOHCA1T).

Refer to the following reports produced by the z/OS Data Collection:

- CA1RPT(TMSSECAB).
- CA1RPT(TMSTMVT) - for r11.5 and below.
- CA1RPT(TMOOPTxx) - for r12.0 and above.

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

- PDI(ZCA10021).

Ensure that all CA 1 function and password resources are properly protected according to the requirements specified in the CA 1 Function and Password Resources table in the z/OS STIG Addendum. If the following guidance is true, this is not a finding.

The TSS resources and/or generic equivalent as designated in the above table are owned and/or DEFPROT is specified for the resource class.

The TSS resource access authorizations restrict access to the appropriate personnel as designated in the above table.

The TSS resource logging is specified as designated in the above table.

Note: CA 1 password resources may require additional analysis to ensure access authorization is justified. CA 1 system password is obtained at offset x'18' from the beginning of module TMSTMVT for r11.5 and below and SHUTDWN option specified in the TMOOPTxx for r12.0 and above. CA 1 Online User Passwords can be obtained from TMSSECAB for all releases or TMOSECxx, if present, for r12.6 and above.
