Discussion

To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems (e.g., web servers and web portals) must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement. Satisfies: SRG-OS-000080-GPOS-00048, SRG-OS-000324-GPOS-00125, SRG-OS-000259-GPOS-00100

The ACF2 data set rules for the JES2 System data sets (e.g., Spool, Checkpoint, and Initialization parameters) do not restrict WRITE and/or ALLOCATE access to only z/OS systems programming personnel.

The ACF2 data set rules for the JES2 System data sets (e.g., Spool, Checkpoint, and Initialization parameters) allow inappropriate access not documented and approved by the ISSO.

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