摘要：An DOS(denial of service) is an attempt by unauthorized processes or users to use the system resources like bandwidth thus denying the fare access of the valid peer. DOS is sub type of Intrusion. Various types of Such Intrusion detection systems are Proposed. Such systems are basically depending upon checking the network behavior and matching the access pattern with a predefined rule pattern. The intruders introduces techniques to break the firewall and such rules. Hence Heirarchial pattern matching sches are proposed. But such schems suffers from matching overhead. In this work we detect the intrusion based on Bandwidth usage Pattern analysis combined with protocol headers pattern matching of the packets that are being exchanged from the system with the internet or network. The system comprises of mainly two component: a Monitor which senses and extracts the packet information from the packets being exchanged, classifier: classifies the packets as being intruding and non intruding and performance analyzer to analyze the system. The system is tested in a real time network an intruding system which attacks another system resources as deniel of service attack.Performance shows significant quick and efficient detection and the detection time is merely. 2 milliseconds. False detection rate is
