摘要：In Intrusion Detection Systems (IDS), the
operation costs represent one of the big challenges for researchers. They are
apart from the IDS cost acquisition and they comprise the costs of maintenance,
administration, response, running and errors reactions costs. In the present
paper, we focus on the missed reactions which include False Positive (FP) and
False Negative (FN) reactions. For that a new optimization cost model is
proposed for IDS. This optimization proposes a minimal interval where the IDSs
work optimally. In simulation, we found this interval as a trade-off between
the damage costs and the FP.
