SQL server Security

I have multiple SQL servers (SQL 2000, 2005 and 2008). I want to create and deploy a security policy/Sec best practices to tighten up security on these servers. Can anyone give recommendations or point me in the right direction?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Multiple servers/instances so the easiest way is to centralise (most off) the authorisation in AD-groups and then instance per instance see that the correct rights are assinged that apply for that version of sql.

A good start is to make an inventory on what exists http://www.mssqltips.com/sqlservertip/1881/sql-server-security-audit-report/

'tighten up' can also mean to make difference in how you try to connect to db. So application roles (from 2005) can limit access to only trough a specific application.
