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.

The IOA will verify that the LTDMMAIN resource in the PROGRAM resource class is restricted to sytem programmers, auditors, and security personnel. The RACF rules for the LTDMMAIN resource specify a default access of NONE and no RACF rules that allow access to the LTDMMAIN resource. Example: rdef program LTDMMAIN uacc(none) owner(admin) audit(failures(read)) - data('added per PDI ZADT0020') The RACF rules for the LTDMMAIN resource is restricted access to system programmers, auditors, and security personnel with access of READ. All RACF rules are defined with UACC(NONE).
