Sarbanes Oxley - What does it have to do with IT Security?

I was looking into Sarbanes Oxley Act and its implication to IT Security.  I ran across this article by Mark Rasch.  He is a very good lawyer with a focus in IT security.  Anyway from his article, I think this is all you really need to know about SOX if you are as lazy as me:

"The thing to remember about SOX is that it is primarily focused on the accuracy of financial reporting data. IT security is important under SOX only to the extent that it enhances the reliability and integrity of that reporting."
