A user has made three failed attempts to access the system through port 23 or a DISA trunk using an invalid username. Each time login fails, the user is locked out for 15 minutes and the event is recorded in the maintenance log. On the third failed login attempt, the alarm is generated. Note: The alarm is generated by an invalid username. Attempting to log in with a valid username and an invalid password does not generate the alarm. Displaying the alarm by entering the Show Fault Security maintenance command is sufficient to clear it.
