Vesconovo: Really I think we need to know _what_ it is they are auditing before we can tell you what the appropriate actions should be on your part.

If they are trying to see how much disk space there is available to the network then there might be a, somewhat questionable, reason to turn off the IDS. However, if these systems are open to the world then tell them to turn up at the console at a given time and you'll show them.

If they are doing a security audit then the are "cheating" by having you remove some of your defenses.

So, what are they trying to audit and we can give you better advice?
