Fix Text (F-17106r1_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 USER CATALOGS. The IAO will ensure that allocate access to USER CATALOGS are limited to system programmers only and all allocate access is logged.
