Awerbuch and Scheideler have shown that peer-to-peer overlays networks can survive Byzantine attacks only if malicious nodes are not able to predict what will be the topology of the network for a given sequence of join and leave operations. In this paper we investigate adversarial strategies by following specific protocols. Our analysis demonstrates first that an adversary can very quickly subvert...
Anomaly based intrusion detection systems rely on the build of a normal behavior model. When a deviation from this normal behavior is detected, an alert is raised. This anomaly approach, unlike the misuse approach, is able to detect unknown attacks. A basic technique to build such a model for a program is to use the system call sequences of the process. To improve the accuracy and completeness of...
