Dempster-Shafer for Anomaly Detection

Intrusion Detection Systems (IDSs) play a pivotal role within network security [1]. IDSs are one of many tools used to detect attacks and intruders of computer systems. It is important to note that the purpose of IDSs is not to prevent the entry of intruders to a system, but to notify the administrator of any observed intruders. IDS techniques can be categorised as either misuse detectors or anomaly detectors. Misuse detection systems, such as Snort [2], rely on intrusion signatures to detect an attack.
