Fix Text (F-18706r5_fix)
Review access authorization to critical security database files. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes required to protect the ACP Files. Ensure that READ and/or greater access to all ACP files and/or databases are limited to system programmers and/or security personnel, and/or batch jobs that perform ACP maintenance. READ access can be given to auditors and DASD batch. All accesses to ACP files and/or databases are logged.
