Risk Analysis Of Enterprise Network Security And Reliability Of The Design And Implementation

With the rapid development of computer network technology and communicationtechnology and the popularity of network applications, the increasing degree, protection andmanagement of network security has become the important topic of enterprise, governmentand University, now, how to establish and improve the network security defense system hasbecome an urgent problem to be solved. Safety is the network survival guarantee, onlysecurity, network to realize their own value. Network security technology is developed withthe development of practice people network, at present the main technologies such asauthentication, encryption, firewall and intrusion detection is an important line of defence ofnetwork security. In addition, the reliability of the computer network to optimize the designaspects of the subject with extensive social benefit and huge economic value.This article first to domestic and foreign research present situation, network reliabilityoptimization design theory, and the reality of the situation described. Then based on anexisting enterprise network structure is analyzed, the influence of physical hardwarereliability of computer network of the enterprise security risk, network security risk,intrusion detection system (IDS) summarized the safety risk management, safety risk, riskfactors. In the enterprise network security requirements, according to the above analysis ofthe actual enterprise security risk, and puts forward a set of general solutions, including:1)improve the technical means to perfect the rules and regulations;2);3) security system;4)the overall network security management. On the base of the overall solution, is designedaccording to the basic design principle of network security, mainly from the physicalhardware selection, data access control, data protection and recovery, virus prevention,safety management in five aspects of optimization design and configuration of the network,thus realizing the optimization design of computer network security goal. Based on thenetwork construction project enterprise, put forward reasonable proposal to improve the whole network, design and optimization of the safety system. Analysis of firewall, intrusiondetection system, access control technology, virtual private network technology, computernetwork security technology, formulate a scientific, reliable, dynamic network securityoptimization design, a design of enterprise network security solution. According to theinvestigation and analysis of network problems, combined with the rapid escalation offirewall, IDS/iPS technology, VPN technology network in construction of informationsecurity system for the enterprise. Through the implementation of the program, theestablishment of the enterprise information security system more perfect, can moreeffectively prevent information system from the aspects of the attacks and threats, greatlyenhance the risk resistance level network.
