A Date Center Network Security Service Management System Design And Implementation

With the development of the Enterprise’s Informationization, enterprises depend heavily on Information System in our country. With the continuous expansion of the scale of enterprises, more and more big trans-regional enterprises and groups have constructed their own business network and information-processing centre for operating and supporting their core business. At the same time, various threats of information security emerge endlessly and have become a new challenge to the security protection of Enterprise network; this completely shows the importance of supporting the network security and exerts great pressure on the stability & high efficiency of the secure management of network. A lot of enterprises construct the Enterprise Network Security Defense System based on the information centre, including the two ways of management and technology. As the saying goes in the information security field: three points depend on technology and seven points depend on management to obtain the information security. The huge investment in the information security construction does not mean realizing the information security. The absence of efficient security management is the bottleneck of supporting the enterprise information security system running at present.The dissertation is attempting to resolve the conundrum of network security management confronting information centres with the internationally popular idea of IT Service Management based on the ITIL(Information Technology Infrastructure Library), and discussing how the domestic enterprises should implement the ITIL successfully.This dissertation firstly introduces the concept of ITSM(Information Technology System Management) and then elaborates the background of its study, the history of its development and its Status Quo. And finally taking one domestic enterprise group as a practical example, the dissertation deals with the integrate frame work design and in detail designs the network security service management system of the enterprise group information and data centre, and realizes the network security monitoring, desk management, block model function etc. Aiming at how to enhance fault diagnosis efficiency and the fault of current user management policy during the information system realization, the dissertation proposes the network fault diagnosis mechanism based on Causality Diagram Pruned and User Authorization Mechanism based on Access Control and Process, and observably enhances the fault diagnosis efficiency and the system security.This thesis is research to promote data center service management concept and application of ITIL IT service management concept based on the combination of using causal graph pruning network fault diagnosis technology and AR System platform, adopt the B/S structure, the use of C# language as a development tool, user rights management module, the module, service platform and configuration design change management module and implementation of the system can run, real time monitoring system, timely detection of problems, early warning to the potential risk, promote the operation mode change to the intelligent, improve the fault diagnosis efficiency, but also greatly enhanced the security of the system. Through the real case, discuss how to design and implementation of network security service management system, and can provide a useful reference for the similar needs of enterprises.
