Research Of Risk Assessment In Network Security Supervise System

The network security supervise system inspecting the network security is dynamic and complex process and it is in the lifecycle of network security supervise system. The menace of this system's safety is from destroy inside,attack exterior,wreck both inside and exterior,contingency of the system itself. So we should analyze the possible menace and information which need protect's risk in term of risk managing ideology, choice proper safety precautions, be apt to any safety risk which may be happen. Thereby, it is essential to do risk assessment in network security supervise system.This paper introduce the network security supervise system and the key technique used at first. a whole network security supervise system can integration many network safety or software, collect kinds of safety information, risk evaluate the net status and give the relevant policy. Risk assessment use scientific method to manage risk, analyze the threaten and frangibility of the net system from risk manage point of view, so it can ensure the safety of network furthest.Followed, particular introduce the course of risk assessment. It includes: the prepare of data; the identify of asset,frangibility,menace; Analyze the relativity of alarms with data mining; the report of risk assessment. Evaluate when safety affair occur, what degree it will do harm, bring forward the pertinence resist intimidator defend countermeasure and keep away from it .The characteristics of this model are as follow: the merger and filtrate of alarms, alarm relativity analyses and unify managementLastly, this paper compared the data mining method with the traditional technique of risk assessment .Analyze the disfigurement of tradition risk analyze method, compare the superiority in network security supervise system's risk management which uses data mining.This design has analyzed the alarm relativity with data mining, implemented the risk assessment of some unit's network security supervise system, advance the efficiency and veracity of alarm relativity. It provided a exact and realism method to the network security supervise...
