Fix Text (F-17038r1_fix)
Review access authorization to critical system files. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes required to protect APF Authorized Libraries. The IAO will ensure that update and allocate access to all APF-authorized libraries are limited to system programmers only and all update and allocate access is logged.
