Detection and Control of Abnormal Behavior in Controlled Network System

Abstract

This paper introduced the concept, the classification and the control principal of network behaviors,discussed the concept, composition and structure, and the behavior control of the controlled network system, then proposed the detection and control model of abnormal behavior in controlled network system. This model of abnormal behavior detection was designed by combining misuse and intrusion detection mechanism, and is the specific application of the research on network behavior and controlled theory, and it controls the network behaviors especially abnormal behaviors. The theory is the basis for establishing the dynamic controllable network security system. With the development of network and information technologies, it seems that the network size, the diversity of network equipment and the complexity of network topology structure are constantlyincreasing, which leads to the probability of security problems emergeis also increasing. However, the traditional network security measures cannot meet the needs of the actual complex network activities, the existing information network has an urgent need to propose a new theory or new method which can reflect the overall network security and behavior control states. As a kind of efficient, scientific and reasonable network security theory, the controlled network is the integration of existing network security technologies and measures, and the aim of it is to construct a controlled network and solve the network security problems(1).
