Can anyone please provide specific details on internal control compliance as related to SOX?

Answer 1

Specific details would be in The Sarbanes-Oxley Act of 2002 itself. Short of that, here is a write-up by AICPA on Section 404, the section that deals with internal controls.

Answer 2

Basically (from my understanding) companies have to go through their internal controls processes to find where any possible errors may occur and check and recheck that none do. It's a long arduous process that has helped overall. There was a recent Wall Street Journal article about the 404 compliance taking a lot of time and efficiency, but overall giving companies better control of their accounting.
