MS SQL Server Auditing Tool

Databases are critical to enterprises because they store confidential data. Hence it becomes important to monitor database logs. But manually auditing them is a herculean task because of the enormous amount of log data generated. ManageEngine's EventLog Analyzer is a comprehensive log management tool that makes it easy for you to monitor all database activities, audit user accesses, track database server account changes, and ensure integrity of confidential data stored, especially in your MS SQL server database.

SQL » 24003: Login failed

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).
