Fix Recommendation

The IAO will work with the systems programmer to verify that the following are properly specified in the ACP.

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 ACF2 tables in the zOS STIG Addendum. These tables list the resources, access requirements, and the resource type for CA 1 Function and Password Resources; 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 NONE.

The ACF2 resource access authorizations restrict access to the appropriate personnel as designated in the above table.

The ACF2 resource logging is specified as designated in the above table.

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

$KEY(BLPRES) TYPE(CAT)
UID(tapeaudt) SERVICE(READ,UPDATE) LOG
UID(syspaudt) SERVICE(READ,UPDATE) LOG

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 ACF2 resources and/or generic equivalent as designated in the above table are defined with a default access of NONE.

___ The ACF2 resource access authorizations restrict access to the appropriate personnel as designated in the above table.

___ The ACF2 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.
