Security Auditing
Security Auditing is a feature in OpenVMS that allows the system manager to track certain system events such as logins and access to resources for security purposes. Each time an audited event occurs, a record is made in the security audit log file that contains information about that event.
The ANALYZE/AUDIT utility allows you to view the audit log file. The SET AUDIT command defines the classes of events that are tracked in the audit log file.
