Appendix C - Audit Policies and Security Event IDs

It is recommended to use the 'Add Extended Event' button on 'Audit Policy Configuration' to capture the extended events. The available Extended Events depends on the version of the SQL Server installed on the machine. Snare captured the available Extended Events and categorized them in Channel and Categories. These channels and categories also depend on the version of SQL Server installed on the machine. There is also a section 'Group Level Extended Events' on 'Add Extended Event' form. This section contains the most common Extended Events that are available on all the versions of the SQL Server. The following table shows the Extended Events in each of the group.

Extended Event Package Name	Extended Event Name	Extended Event Description
Logon or Logoff
sqlserver	login	Occurs when a successful connection is made to the Server. This event is fired for new connection or when connections are reused from a connection pool
sqlserver	logout	Occurs when a user has logged out of logged off the Server. This event is required in traces that will be used for Replay
sqlserver	prelogin_traceid	Occurs when a prelogin containing a traceid arrives on a connection.
sqlserver	ual_instrument_called	Occurs when a successful connection to the Server is reported to Windows using the User Access Logging API. This event is only fired for new connections. Connection resets are not tracked.

sqlserver	object_altered	Occurs when an object was altered by the ALTER statement. This event is raised two times for every ALTER operation. The event is raised when the operation begins and when the operation is either rolled back or committed. Add the nt_username or server_principal_name actions to this event to determine who altered the object.

The event is raised when the operation begins and when the operation is either rolled back or committed. Add the nt_username or server_principal_name actions to this event to determine who altered the object.
