A Theoretical Exploration of the Impact of Packet Loss on Network Intrusion Detection

In this paper we review the problem of packet loss as it pertains to Network Intrusion Detection, seeking to answer two fundamental research questions which are stepping stones towards building a model that can be used to predict the rate of alert loss based upon the rate of packet loss. The first question deals with how the packet loss rate affects the sensor alert rate, and the second considers how the network traffic composition affects the results of the first question. Potential places where packet loss may occur are examined by dividing the problem into network, host, and sensor based packet loss. We posit theories about how packet loss may present itself and develop the Packet Dropper that induces packet loss into a dataset. Drop rates ranging from 0
