Fix Text (F-17046r1_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 libraries containing modules listed in the Program Properties Table (PPT). The IAO will ensure that update and allocate access to libraries containing PPT modules is limited to system programmers only and all update and allocate access is logged.
