Vulnerability Discussion
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.
Audit records can be generated from various components within the information system (e.g., module or policy filter).
Check
If the Mainframe Product does not have the function or capability for user logon, this is not applicable.
Examine configuration settings.
Determine if successful/unsuccessful logon attempts are audited. If they are not, this is a finding.
Fix
Configure the Mainframe Product to provide audit SAF to call when successful/unsuccessful logon attempts occur.
