摘要: We present a method of analysis for evaluating intrusion detection systems. The can be used to compare the performance detectors, evaluate goals and determine best configuration an detector given environment. uses decision that integrates extends ROC (receiver operating characteristics) cost methods provide expected metric. general results illustrate in several numerical examples cover range detectors meet goal two actual realistic demonstrate that, contrary common advice, value system optimal operation depend not only on system's curve, but also metrics hostility environment as summarized by probability intrusion. Extensions are outlined, conclusions drawn.
