Title

zOSMF resource class(es) must be active in accordance with security requirements. (Cat II impact)

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.

Check Content

From the ISPF command shell enter: SETRopts list If the ACTIVE CLASSES list the EJBROLE, LOGSTRM, SERVER, TSOPROC, ZMFAPLA, and ZMFCLOUD, this is not a finding.

Fix Text

Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option as specified in the example below: The RACF Command SETRopts LIST will show the status of RACF Controls including a list of ACTIVE classes. The above Classes are activated with the command: SETRopts CLASSACT(EJBROLE, LOGSTRM, SERVER, TSOPROC, ZMFAPLA, and ZMFCLOUD).
