Fix Text (F-17241r1_fix)
The IAO will ensure that access to SYSTEM DUMP data set(s) is limited to system programmers only, unless a letter justifying access is filed with the IAO. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes required to restrict access to these data sets.
