Audit of sa logon

  • I have to audit all sa logons to a database. I think the best would be to use the SQL-Server 2008 auditing feature, but the problem is: can I set up the auditing so that ONLY the sa-logons are audited? I really don't want to audit all other logins....

  • Login triggers if you want to only do it for SA?

    Although 'sa' account should be disabled on any SQL Server, unless you mean 'sysadmin' role users?

    You can also in Server properties -> Security -> Log All login attempts (not just Failed Login ones), then Filter in the SQL Server Log

  • Jerry, i have gone through different articles but i am not sure if that suits my requirement. Basically i need the trigger to send me an email when someone logon's to sql server using "sa" account. Can you please point me to the right article or share the script if you have so? Thanks

  • just tested this, and it works fine, assuming you have dbmail setup with a profile;

    --DROP TRIGGER [TR_Logon_Trigger_Track_sa] ON ALL SERVER

    GO

    CREATE TRIGGER TR_Logon_Trigger_Track_sa

    ON ALL SERVER FOR LOGON

    AS

    BEGIN

    --the auditing snippet below works fine in a

    --login trigger,

    --database trigger

    --or any stored procedure.

    IF SUSER_SNAME() = 'sa' and @@spid >=50 --avoid system connections

    BEGIN

    declare @body1 varchar(4000)

    set @body1 = '[sa] Login Event Triggered On ' + CONVERT( VARCHAR( 20 ), GETDATE(), 112 ) + ' '

    EXEC msdb.dbo.sp_send_dbmail

    Thanks. I should have mentioned this before, i am only looking when someone connects using "sa" account not system admin priviledge on sql management studio only, we are using sa account from our webconfig( i know not a good idea) and i do not want to get alert for those. How can i get this? Thanks

  • I am aware that this one is a very old thread!!

    But have need to clear my doubt and have no other go.

    The script works perfect and sends alerts. But my concern is, I am getting blank mails. Could anyone give an explanation, please. So that I will filter it out and receive only when its not blank.

    Thanx

  • as much as I dislike sending emails from within a trigger .....

    Double check you are executing the mail query in the correct database ?

    Check parameter @execute_query_database

  • I have created the trigger in master. I suppose the trigger should be executed from master database only.

    Please let me know if I have to alter the database

  • Better yet, disable the sa login like it should be. Having it enabled subjects your servers to attacks. I saw a SQL Saturday presentation where hacking the login was presented in real-time. It was so simple to hack a known login that it was scary. It made me relieved that mine were already disabled. If security is important to you, lock it down.
