Fix Recommendation

Review access authorization to critical system files. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes as required to protect System-level product installation libraries.

Configure allocate access to all system-level product execution libraries to be limited to system programmers only.

Access other than this should be documented and approved by the ISSO.

Check Contents

The ESM data set rules for the JES2 System data sets (e.g., Spool, Checkpoint, and Initialization parameters) do not restrict UPDATE and/or ALTER access to only z/OS systems programming personnel.

The ESM data set rules for the JES2 System data sets (e.g., Spool, Checkpoint, and Initialization parameters) allow inappropriate access not documented and approved by ISSO.

If both of the above are untrue, this is not a finding.

If either of the above are true, this is a finding.
