Network Information Security Early Warning System And Design

Computer network has already applied on every domain of society extensively, it provides great convenience to our work and life. But when we rejoice about it's expediency, the network security come closely. Inborn crazy factors about network society, such as virus, hacker, illegality incursion, unwell information and so on, they are threating network healthy development continually and network application be up against excessive risks.Facing such an rigor actuality, relevant departments in many governments have to attach importance to the network security, they have exploited many kinds of network security products, such as Intrusion Detection System(IDS), antivirus software and so on to prevent and deal with varieties of crazy factors in order to undertake network security.In face of such condition, network security problems are still rigorous. On the one hand, it is due to network rapid development and a lot of new menaces and attacks have turned up, which technology and means are more progress and secret; on the other hand, it is due to every security products is not perfect, they have some defects and shortcomings to some extent and network information security problems be up against huge challenger.Because of such network security condition, I expound network information security early warning systems, analyze network security mechanism, give security model of system, and on this basis I analyze system, design frame and investigate key technology in this system, considering network security problems totally and deeply and combining school network actual situation. At last anthor summarize what it do, and expound the next research orientation.
