Re: security against dba´s

I used to have a professor who was a DBA for a long time. She said: Be a DBA. The closer you are to the data, the more 
dangerous you are, and the more they'll pay you.

While that's funny, it's also kinda scary and true. Whoever is administrating your database will actually need access 
to your database. In this case, the security measures you need probably aren't ones that will protect your database 
from your DBA. That's only going to make their job harder, and consequently, they'll find some way to circumvent the 
measures so that they can do their job easier.

Instead, you need auditing measures and access restrictions, if possible. Have systems in place that will log database 
transactions. This way, the DBA can access the data, but it will always be known what data is being accessed, and by 
whom. Secondly, deny read access to the data your DBA can't see if you REALLY must.

Finally, I hope you trust your DBA and have done some background checks, but based on your post I have a feeling this 
isn't the case.

Hope this helps!
