Intranet Design And Implementation Of Network Security System

Information technology and networking is the world's economic and social development trend of ever-changing computer networking technology, business development of information technology increasingly dependent. At the same time, due to a computer network with the openness and sharing, their safety has become a growing concern. This system analyzes the major technical enterprise network security, and a typical enterprise network security solutions, for example, discuss the design of network security solutions and their specific implementation.Firstly, the author summarized the present situation of computer network security, computer network security of the definition and the information system security elements, and then introduced the main technology of computer network security, including information encryption technology, identity authentication technology, grant access and control technology, firewall technology and computer virus protection technology. According to the enterprise network information security features and network information security needs of enterprise internal network, network security risk analysis, including technical vulnerability analysis, management vulnerability analysis, threat analysis, against type analysis source, risk identification and sure, etc. On this basis, combining with the enterprise network environment, according to the security system of risk analysis and network security needs and goals are given, and the enterprise network security solutions of general design and safety strategy, and illustrates the network security system of the concrete implementation. The paper to the enterprise network further safety design technology were discussed.
