Title
The CA-TSS SUBACID Control Option must be set to U,8. (Cat II impact)
Discussion
In certain situations, software applications/programs need to execute with elevated privileges to perform required functions. However, if the privileges required for execution are at a higher level than the privileges assigned to organizational users invoking such applications/programs, those users are indirectly provided with greater privileges than assigned by the organizations. Some programs and processes are required to operate at a higher privilege level and therefore should be excluded from the organization-defined software list after review.

Fix Text
Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option setting to "SUBACID(U,8)", and proceed with the change.
