Design And Implementation Of Network Security Planning For Large Enterprises

With the development of science and technology,the computer network technology is becoming more and more diverse.At this stage,the computer network as a link,connecting people's daily life and work needs.However,how to ensure the safe operation of the network is a key problem to be considered when building a network.Large enterprise network as the normal operation of the supporting point,with the expansion of the size of the enterprise,its branches at all levels continue to expand,the network has become complex.Thus,large enterprises at all levels of the organization of the network communication,the problem is faced with all kinds of security threats.Large enterprise data on the network may be passive or active attack,which includes data is intercepted,network connection interruption,important information is being tampered or forged and other risks.When the enterprises in different places to set up many branches,the enterprise network security and stability of the relationship between enterprise information security,building a system of security network environment becomes very necessary.Network security involves a large number of science and technology,not only contains the computer science,it is a three-dimensional scientific field.This determines the security of the network is not only to solve the problem from point and line,but should be a comprehensive consideration,from point to line,from the line and the security issues in the network.Network security should be in the premise of ensuring the normal operation of the network,to ensure that the network transmission of data is not tampered,damage,theft,so that the network equipment,the terminal is not damaged,the business system can be stable normal operation.The problem of network security is how to ensure the information security and stability of the network transmission,so that the information can not damage to the destination.In this paper,we study how to build a large enterprise network,and focus on the security of the inter domain network,and discuss how to manage the large enterprise networks.Firstly,the technology of network security and network access technology is introduced,which includes firewall technology,computer virus and its prevention and control technology.Through the introduction and analysis of the above technologies,combined with the actual needs of the construction of large-scale enterprise network security,the paper puts forward some suggestions on the network planning of large enterprises.At the same time to develop a reasonable plan and design.On the basis of the design scheme,combining with the actual situation of large enterprises,the implementation of the plan is carried out.In the process of the scheme design,considering the large enterprise network security system,taking into account the rationality of large-scale enterprise network security,saving the cost of large enterprises,improve the scheme's performance ratio.In the process of the design,the related suggestions are put forward for the management and emergency system of the network operation.Through the "soft power" of the system,the hardware can be alleviated to some extent,and it can improve the robustness of the network.In the implementation of the scheme,the hardware aspects of the network equipment,including the physical environment,equipment configuration,software design and architecture of the software is not the focus of this paper.
