IBM Sensitive Utility Controls must be properly defined and protected.

To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoW-approved PKIs, all DoW 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.

If the RACF resource access authorizations for the following sensitive utilities restrict access to the appropriate personnel according to the site security plan, this is not a finding.

If all access for these sensitive utilities is audited, this is not a finding.

The RACF resources as designated in the table above are defined with a default access of NONE.

The RACF resource access authorizations restrict access to the appropriate personnel as designated in the table above.

The RACF resource rules for the resources designated in the table above specify UACC(NONE) and NOWARNING.

The following commands are provided as a sample for implementing resource controls:

RDEF PROGRAM AHLGTF ADDMEM('SYS1.LINKLIB'//NOPADCHK) - DATA('ADDED PER SRR PDI RACF0770 ') - AUDIT(ALL(READ)) UACC(NONE) OWNER(ADMIN) PERMIT AHLGTF CLASS(PROGRAM) ID(stcgsmpl)
