Title

The number of ACF2 users granted the special privilege CONSOLE must be justified. (Cat III 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. Access control policies include: identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include: access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed by the application to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, and domains) in the information system.

Check Content

From the ISPF Command Shell enter: ACF SET LID SET VERBOSE LIST IF(ACCTPRIV OR CONSOLE OR OPERATOR OR MOUNT) If the number of users granted the special privilege CONSOLE is strictly controlled (issued on an as-needed basis), this is not a finding. If the number of users granted the special privilege CONSOLE is not strictly controlled (issued on an as-needed basis), this is a finding.

Fix Text

Define the CONSOLE attribute with minimum access and it is controlled and documented. Documentation providing justification for access is maintained and filed with the ISSO and that unjustified access is removed.
