24003: Login failed
Event 24003 occurs when a user attempts to log in to an SQL server and fails. Repeated occurrences of this event in a short span of time could indicate an attack on the server. Therefore, auditing this event is essential for maintaining server security. Action groups consist of all the relevant events together, making it easy for an administrator to identify an event's type just by looking at its action group. This event is generated by the FAILED_LOGIN_GROUP action group. This event includes important information, like the:
- Date and time at which the failed login attempt occurred.
- Session identifier of the event.
- Name and type of the target object (in this case, the SQL server login).
