    Security Analysis
    This paper,on the base of the present network security threats,introduced a number of common security measures,and discussed in detail the implementation of network security strategy adopted and the corresponding mechanism,and gave a more reasonable model for network security protection.By using a variety of security technologies,including network security management,intrusion detection mechanisms,security response mechanism,firewall policy,network security restore,the model can play a protection role well.

    Network security issue is the present hot spot in today's society and network security has become a foundation of national normal running, the problems in seven major aspects in our country are mainly the aggravation of the crime of the information and the shortage of the talents of network security. The realization of network security technology is the guarantee of realizing the goal of network security, including such means as the technologies of secret code, firewall, visit-control, detection and ID authentication.

    Network security is becoming more and more important with the development and application of modern information technology. A preliminary study of network security抯 meaning, threat and objective is made in the paper, and also an introduction to network security's various techniques, tactics and developing tendencies is given, which will greatly help us to understand network and network security.

    With the extensive application of computer network technology,security problem can not be ignored. Computer network, as an open system, has to face up to various threats and attacks. So the establishment of a network security system is crucial and it involves aspects from the hard ware to the soft ware of the system. This paper introduces the threats to network security in several aspects,and puts forward a strategy and method to build a safe computer network.As a result,the threats to network security are reduced and network security is improved?

    Objective To value and pay much attention to the security problem of network.Methods The writer analysed the security threat in network and the security technique in current network and got the security strategy of network.Results With the application of the security technique and the security strategy in network, the security problem in network gets good improvement.Conclusions Security problem in network is a very important system,it needs to moderate the match mutually in many ways to become a complete safety guarantee system.In order to abtain ideal network security,there is still a long way to go.

    Network security is a complicated system engineering issue,and to guarantee network security,it is necessary to set up a whole set of security insurance system and adopt advanced security insurance techniques and management methods.The paper introduces first the concept and characteristics of computer network security,then analyzes how to achieve network security by using network security policy and security technologies.It thoroughly discusses a network security system based on AP2DR2,which is a multi-level and comprehensive dynamic defense system.The development trend of network security system is the transformation from static and passive state to dynamic and active state.
