George and all,
A bugzilla approach might make more sense, so that the appropriate developers are afforded the opportunity to address any issues with their
Hmm, not sure. That kinda implies that "false positives" are "bugs" in NIDSs, which (IMHO) they are not. Again IMHO, FPs are inherent to signature-based ID and can be reduced (via many means), but not "turned off" (I am assuming everybody saw this equation of FPs vs FNs). The most recent realization I had on that was when my Dragon NIDS produced a P#RN signature as a result of somebody reading an Apache manual (just like the signature doc said it might) :-) Obviously, NIDSs are still incrediblky useful in spite of that! I suspect that vendors might want to adjust signatures if there are persistent reports about some particular sig being very FP-prone, but not really based on every single report. Best, -- Anton A.
