Fix Recommendation

Ensure user IDs assigned to zSecure started tasks and scheduled batch jobs are assigned the PROTECTED attribute and/or defined as an STC.

The following command is provided as a sample for adding the PROTECTED attribute. Convert this command for any other ESM:

- ALTUSER <stuser> NOPASSWORD NOPHRASE
- ALTUSER <batch user ID> NOPASSWORD NOPHRASE

Check Contents

If user IDs assigned to zSecure started tasks and scheduled batch jobs are not assigned the PROTECTED attribute and/or defined as an STC, this is a finding.

The default zSecure STC names (that may be changed by installation) are as follows:

- STC C2PACMON runs program C2PACMON.
- STC C2POLICE runs program C2POLICE.
- STC C2PCOLL runs program CKFCOLL. (CKFCOLL is also run as a step in batch jobs.)
- STC C2RSERVE runs program BPXBATCH.
- STC CKCS1154 runs program CKCS1154.
- STC CKNSERVE runs program CKNSERVE.
- STC CKCCEF runs program CKRCARLX.
- STC CKQCLEEF runs program CKRCARLX.
- STC CKQEXSMF runs program CKQEXSMF.
- STC CKQRADAR runs program CKRCARLA.
- STC CKXLOG runs program CKXLOG.

Verify the naming conventions for the zSecure STCs and batch jobs with the responsible systems programmers.

Check which user IDs are assigned in the STDATA segment of the zSecure STCs. For these user IDs, verify they are assigned the PROTECTED attribute.
