All Cabinet people resign. It's up to the President to accept their resignations.
In any case, I expected Ridge to resign. He can make a load of money in the private sector as an expert consultant in the field of national security.
Lowering the threat level so that you can raise it again makes you an expert?
Oh ye of little importance (hehehe), he does more than changes the threat level of the nation. He has a lot of knowledge regarding the national security infrastructure and policies; more than most. That is very marketable in the current environment.
