| Abstract(in English) | The serious situation, in which the network service will not be provided to the users, may occur when the network is filled with the massive traffic produced by network worms. The earlier the network worm be detected, the more effectively the network service provider can take an action. Because the new types of worms are produced in a stream, the detection of an unknown worm is important as well as taht of the known worms. This paper proposes an anomaly detection scheme of the network. The scheme defines the normal state by traffic monitoring of the network and expresses the degree of anomaly of the current state in a numeric form as how far the current state is deviated from the normal state. The simulation shows that the degree of anomaly corresponds to the amount of the abnormal traffic such as port scans. |
