    The answer to a question with absolutely no detail will always be, "It depends."

    Are your IDS sensors appliances? If so, then the answer is no. More than likely, it has a hardened unix OS running on it and additional add on software is not necessary. Then again, you've provided 0 detail here so don't take this as an absolute.

    If you have a host based console (i.e. running on Win2k or the like) then yes, the console is like any other host on your wire. It needs to be protected. If you have host based IDS software on workstations then you should also look at layering defenses and of course add the necessary protections such as AV.

    One IDS Sensor on a machine with hardended windows OS and two ethernet cards.

    Other one is a host based IDs, we have an antivirus running on it.
    Thank you for the reply.

    Well, I would certainly check with the vendor before adding anything that might void your support contract.

    Also consider that realtime AV on an IDS will certainly increase the overhead needed to keep up with high traffic loads and may cause the box to drop packets (again, there are many facts here that I don't have, such as horsepower of the box, so this is a generalized statement). This of course is not a desireable side effect.
