After all, how infosec is related to SOX??

Yes, a lot of security professionals went to the bill's text and were not able to find anything related to information security, even when directed to sections 302 and 404. I was very happy to find this post from the eIQnetworks blog today, as it is written in the same exact way that I use to explain this issue to those who ask me. So, to save some words, you can go directly to their post.
