Fix Recommendation

All batch jobs scheduled via an automation process will use the //*LOGONID xxxxxxxx card in the JCL stream to identify the userid. Use restricted logonids with the following parameter coded:

RESTRICT

One or both of the following will also be specified:

PGM(xxxxxxxx) and SUBAUTH
SOURCE(xxxxxxxx)

The use of default IDs prevents the identification of tasks with individual users as mandated by policy, and prevents adequate accountability. Default IDs for batch processing will not be used.

The use of USER= can also be used in the jobcard to identify the userid to be used for a job's processing.

Check Contents

From the ACF command screen enter:
SET LID
SET VERBOSE
LIST IF(RESTRICT)

If the logonids that are associated with batch jobs have the RESTRICT attribute, then the logonids must also have the PGM(xxxxxxxx) and SUBAUTH attributes, or the SOURCE(xxxxxxxx) attribute specified.

If all restricted logonids have the PGM(xxxxxxxx) and SUBAUTH attributes, and/or the SOURCE(xxxxxxxx) attribute, this is not a finding.

If the PGM(xxxxxxxx) and SUBAUTH attributes or the SOURCE(xxxxxxxx) attribute is not specified for any restricted logonids, this is a finding.
