CCI(s)

• CCI-001499 - The organization limits privileges to change software resident within software libraries.
• CCI-000213 - The information system enforces approved authorizations for logical access to information and system resources in accordance with applicable access control policies.
• CCI-002235 - The information system prevents non-privileged users from executing privileged functions to include disabling, circumventing, or altering implemented security safeguards/countermeasures.

Fix Recommendation

Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes as required to protect JES2 System data sets (spool, checkpoint, and parmlib data sets).

Configure WRITE or greater access to JES2 System data sets (spool, checkpoint, and parmlib data sets) to be limited to system programmers only.
Access other than this should be documented and approved by the ISSO. (Example: All SYS1.HASP* data sets.)

Check Contents

The ESM data set rules for the JES2 System data sets (e.g., Spool, Checkpoint, and Initialization parameters) do not restrict WRITE or greater 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 is true, this is a finding.
