Fix Text (F-20441r1_fix)
Review access authorization to critical system files. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes as required to protect the MASTER CATALOG. The IAO will ensure that greater than READ access to MASTER CATALOG is limited to system programmers only and all greater than READ access is logged.
