Description
CA Auditor can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to product resources could result in the compromise of the operating system environment, and compromise the confidentiality of customer data. Many utilities assign resource controls that can be granted to system programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.

Fix Text (F-25928r868067_fix)
The IOA will verify that the LTDMMAIN resource in the PROGRAM resource class is restricted to system programmers, auditors, and security personnel. The ACF2 rules for the resource specify a default access of NONE. There are ACF2 rules defined and only system programmers, auditors, and security personnel have access. Example: SET R(PGM) $KEY(LTDMMAIN) TYPE(PGM) UID() ALLOW UID() ALLOW UID() ALLOW UID(*) PREVENT DATA(SRR FINDING FOR CA AUDITOR)
