Title

zOSMF resources must be protected 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, for each appropriate resource class enter: RL <Class> * AUTHUSER For EJBROLE, LOGSTRM, SERVER, TSOPROC, ZMFAPLA AND ZMFCLOUD resources class. Review Appendix A in the zOSMF Configuration Guide: Security Structures for z/OSMF Requirements for the Security Configuration tables. If RACF access rules for each resource are restricted to appropriate users, this is not a finding.

Fix Text

Review the access requirements in the Appendix A in the zOSMF Configuration Guide: Security Structures for z/OSMF Requirements for the Security Configuration tables. Configure access for resources in accordance with the site security plan.
