—This paper describes packet header anomaly intrusion detection system modeling. The essence of the discussion in this paper is on applying knowledge discovery in database technique to produce expert production rules which is one of the main components of our model which we call as Protocol based Packet Header Anomaly Detector (PbPHAD) Intrusion Detection… (More)
This paper describes an experimental protocol based packet header anomaly detector for Network and Host Intrusion Detection System modelling which analyses the behaviour of packet header field values based on its layer 2, 3 and 4 protocol fields of the ISO OSI Seven Layer Model for Networking. Our model which we call as Protocol based Packet Header Anomaly… (More)
namely UDP, TCP and ICMP to identify the degree of maliciousness from a set of detected anomalous packets identified from the sum of statistically modelled individually rated anomalous field values.
