Here is an interesting interview question. You have a PC in front of you, switched off,  with a database on it. You don’t know any of the passwords and you want to get at the database. Is this possible? If so, then how?

This happened to me recently, due to a freakish accident concerning me reacting stupidly and impetuously to the death of a domain. I was left with a development database I had to get to urgently, (Backup of development work? Of course, on the local hard disk!) and I had no idea of any of the passwords. Normally, I'd never have bothered to find out by trying.

In my case, it was ridiculously easy, once the feelings of panic had subsided. I just downloaded a utility from the internet that blanked out all the Windows passwords. Because the BIOS was not secured by any password, I could boot up with a CDROM, blank out the Windows passwords, and then, once more, I was god in this little PC world. At first, I stopped the SQL Service and copied the MDF files off and re-attached them to another SQL Server. Then I realised that I had gained admin rights to the database anyway through a local account. If all else had failed the backups weren’t encrypted anyway, so I could have got at them without any bother.

I was just chucking to myself over a cup of coffee about my foolishness in getting in a panic about losing the database. It then occurred to me how wise it is to treat server rooms like forts. I could immediately think of several commercial databases with unsecured BIOSs.

The problem with Database Developers and DBAs dealing with security issues at this level is that they have the wrong mindset. Finding security loopholes is a job for a different sort of thinking. The best security experts I know have a built-in malicious streak. They are like hunters that thrill to run down, and kill, a beautiful wild creature.

In the meantime, we innocents carry on believing that intruders cannot get at our data by gaining admin rights to the database. I realise that most production servers are properly nailed down and their server rooms secure and monitored, but for the rest of us, maybe it is time to think again.
