Heh... I take the low road... disable all logins (except mine), answer the phone to see who's squawkin' Wink (just kidding... in most cases Tongue )

Great article, David!

I pretty much use an identical script to stop developers accessing the live server.

Unfortunately I can't disable their logins (as much as I would like to Tongue) as they are allowed (by the business for 'support' purposes) to use the standby/logshipping server to access data and since permissions are replicated across, they have to remain in place.

The main reason we don't want them accessing the live server is so they don't change data (in the case where they know the account password from a legacy system) and also so they don't put load on the server if they run a massive query.

The best part of my script - KILL @SPID BigGrin

Hello,

could you please tell my why you would not use profiler to audit logins?
Is this putting too much burden on the server?

Thanks!

Best Regards,

I had much the same problem some months back. Group of developers felt they were above the rules and were fiddling on Prod using a SQL account for a messaging application that they were maintaining.

Couldn't disable the account, cause the messaging is a critical process (inter-bank money transfers). Could change the password, but would have had to tell developers so that they could configure the messaging app with new password (and the app keeps the password clear-text in it's properties) Crazy

The security officer threatened them with diciplinary hearing and possible dismissal, but management did nothing more than slap them on the wrists. They were 'valuable employees'

When SQL 2005 SP2 came out, I dumped a login trigger on the prod box that rolls back any connections that cme from the app's login that use a querying tool.

The screams were soooo pleasant to hear. BigGrin

Good stuff as always David!

My two cents; firewall rules to block developers from direct access to production is a very cool thing, and probably easier to sell in the SOX era than killing the legacy apps. Doesn't eliminate the problem, but makes it hard for them to abuse. The other point is that hostname can be spoofed on purpose or accidentally. I don't know if it still does it, but when you linked a table in Access it would store the host name as part of the connection, so if you copied the MDB to someone else it looked like they were running from the original machine.

... The other point is that hostname can be spoofed on purpose or accidentally ...


We had a group of developers (from before my employment) use this to identify the class of a process. Unfortunately for me, this was then used in other processes to automate other processes, so now I'm stuck in a sea of "I can't tell which computers the connections are coming from", so I've turned to using MAC addresses (sysprocesses.net_address). I'd think this would be a much more reliable method of determining which computers are connecting, but I know almost nothing of MAC addresess and haven't figured out how to tie them to an IP address without explicitly checking the MACs of each of our computers.

The line:
INSERT INTO @InputBuffer(EventType,Parameters,EventInfo) EXEC (@SQL)
gave me an error:
Server: Msg 197, Level 15, State 1, Line 65
EXECUTE cannot be used as a source when inserting into a table variable.

What happens?
