Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one.

Check

Fix
Configure the Mainframe Product to provide audit SAF call for starting and ending time for user access to the system.
