I'm studying CIW, I'm not so sure about the value of this certification, but I hope this can drive me study hard.
Thanks for giving us a technical forum.
Becareful IS Auditor must question you with "potential risk" when you say" Everything is running properly for there is no any incident". Because criteria of "safe and under control" is: management control and technical control should satisfy business requirement. You know it's true that whatever you try your best and nothing shows threat but potential risk exists forever.
