Abstract:
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?Cite
Network security is of great importance to the state security and construction. But network is faced with a variety of imperilments. It is necessary to present a relatively perfect network security system.

In view of the importance of researchers sharing the same concept of network security, this paper proposes a model in which network security issues can be treated integrally. The importance of network security has been recognized for some time, but providing networks (especially public networks) with security functions has proved difficult. The role of the network itself in computer network security has been minimal, as computers inevitably maintain their own security. To resolve these problems, this paper proposes a network security reference model.

With the rapid expansion of the rapid development of computer network technology and network coverage, network security issues are increasingly complex and outstanding looks up.In this paper, we have the analysis of the CAN security situation, put forward the principle of network security policy-making process to be followed, clearly a number of network security policy are also pointed out to build a more complete network security solution ideas.For the current CAN security issues, we discuss the principles and methods of the CAN network design process involved in the security system, and propose specific means for the CAN technology features.Meanwhile, we have researched and explored the characteristics and design of school network management, combined with the existence of the local area network insecurity, indicated security needs of the network, and to developed appropriate the security policy of network.

At present computer networks are developing at a high speed. How to strengthen the security of computer network is a problem that we need to solve urgently, This paper focuses on the causes of network security and the major threats, Take the security hidden danger as the starting point, two aspects of technology and safety management are expounded. Propose solutions and implementation plans. This article mainly expounds: Firewall; Network virus; Cloud computing, security. Intrusion detection, virtual network, Cloud security technology and practical applications to do a comprehensive interpretation.

With the rapid development of information technology, the influence of network on human way of life is greatly enhanced, and network technology is rapidly popularized in all fields of society, which makes the security of computer network become an urgent problem to be solved. How to ensure the rapid and healthy development of the network has become the focus of attention of scholars, and has a very prominent realistic background and extremely important theoretical significance. In this paper, the research background of computer network security, the significance of this paper, the related research status at home and abroad and the research methods used in this paper are summarized. Then the theory of network security technology is advanced. This paper summarizes the connotation of network security, the research content of network security, the framework of network security information and the dynamic model of network security. In the third part, the problems of computer network security are analyzed, and the network security problems are studied from four aspects: network hardware, network software, network managers and network users, and the possible network security problems and their causes are analyzed. In the fourth part, the network security protection measures are put forward, and the security measures of hardware system, system security loophole, application software and manager are put forward respectively.
