Title

Update and allocate access to all APF -authorized libraries are not limited to system programmers only. (Cat I impact)

The Authorized Program List designates those libraries that can contain program modules which possess a significant level of security bypass capability. Unauthorized access could result in the compromise of the operating system environment, ACP, and customer data.

Fix Text

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.
