[edit] What you should do

This may indicate that an unauthorized party is attempt to access an account that has been disabled on the system, and may indicate an attack is in progress. This event should be investigated. Check the GUI for additional events from the source to determine if this is part of a larger effort to gain access to your systems.

The platform will track this logon, and if multiple events occur will issue a higher level alert that a brute force attack may be occurring.
