The Study On Design Method Of System Security Scheme

With the rapid development of global informationization, network has become popular to people's study and work in various fields. It had brought a great convenience to people in the enjoyment of network, but at the same time, people had met a great harm of various of intrusion and attack on the network, which aroused extensive concern to network security. We need to take some preventive measures to reduce the losses caused by attacks.This thesis based on the task study deals with "the integration design of system security" as the background to develop the research. First this paper followed the domestic and international present condition to study a great deal of knowledge and information about security, on the basis of reading a large number of criteria for network security risk assessment, summarize the relevant security assessment criteria and its development path. Then Particular statement for design target, design principle and design basis to the system security design, and analysis the main threats and risks to the information system, give a risk analysis of security needs to them, which would set out the relevant security policy. At last it uses the above theory research results in expatiating the realization parts of the software about the security program design, this software can help designers realize the possible risks and the relevant measures.
