Auditors Special Network Security Analysis, Design And Deployment

Audit is the audit organs of information communication network of the basic platform, is an important component of electronic governmental affairs. Audit network system is based on the e-government network and part of line constitutes a multi-level, large-scale, complex interactive network system,Need high security and stability, the open system to meet the operational security communication.Therefore, the study on audit network security solution is very urgent and necessary, its broad application prospects.Based on the network system security audit demand and a variety of security technology research, explore the suitable audit network security system, proposes the audit network security solutions, and implement and application.First of all, a full analysis of the audit network security requirement, give audit network security system structure, then the system structure of the components were analyzed.Audit network security includes security, data security audit business audit, audit network security, physical security and environment security.Therefore, network security audit system by the infrastructure layer, network layer, service layer, security authentication of security protocol layer, thereby realizing the audit network operation and data integrity, authentication, non-repudiation and review.Then, to audit the network system security system security authentication and access control technology research.Using PKI/PMI technology combined with U锁technology, analysis of the network security audit system of identity authentication and access control:in view of the audit network data integrity, non-repudiation and timeliness requirements of high characteristic, to identity authentication and access control system based on analysis of the audit, network data transmission security.The audit system of network collaborative multi unit and joint audit, improve audit ability, realize the sharing of resources.However, because of the openness of the Internet, network security audit is inevitable.Through the study on network security auditing system,Improve the audit system of network security, stability, confidentiality,Provides the basic guarantee of safety for the wide application of audit network, has far-reaching significance for the application and popularization of the network audit.This paper is mainly to solve the basic hardware facilities audit network layer, service layer, network layer security protocol layer security authentication, security protection and authentication and access control, data transmission security and other important issues.
