While I was waiting for the previous post to come back from my proof reader. I ran across a rather like minded post I thought it might be helpful to share.
Suzanne Obermire at RRW Consulting posted a nice summary of an article by bmighty.com: 10 Database Security Tips For Smaller Businesses. The article she references may be a bit steep for the non-technical crowd, but her summary of it is a good read. You can find it here: Ten Database Security Tips
Makes a good read while you wait for me to fill in this section with more content.
