The Research On Network Security Domain Division Scheme Of Telecom Operation Enterprise Supporting System

The production department of telecom enterprise has a lot of supporting systems. These systems and other systems compose a large and complex computer network. Each network is connecting with others but is independent from others. Every network security mechanism is different so that it may affect availability of the network when adjusting a network. And there is a big hidden trouble of the telecom enterprise network because a detailed analysis is never been done for the security of the network. Therefore the most important work of telecom security is how to ensure the safety and reliability of the telecom support system.Security domain division scheme of hierarchical protecting telecom enterprises is proposed after researching the security domain of telecom enterprises. Security domain division which is not physical isolation traditionally is in the premise of analyzing security requirements and security threats of every supporting system. According to this plan, network structure will be more reasonable and more safety. Reasonable security domain division is the basis of develop and implement safety protecting measures.The main research of this paper isFirst of all, analyze the current situation of security of the telecom network. Then discuss deficiencies and problems of security domain division scheme which is carried out at present.Secondly, design a new security network domain division scheme of telecom operators’supporting system which is focused on the structure of telecom network according to the ideas of network structured.Thirdly, according to the boundary protection method of information safety grade protection, in view of the different boundary between each security domain, formulate border safety protection strategies, including security access measures, safety equipment deployment, etc.Finally, apply the security domain division scheme to operational telecom network. Take measures based on border security strategy. The scheme is feasible in practice that proved by the successful application.The main innovation of this paper lies in:design a new security network domain division scheme of telecom operators’supporting system, which have been testified in practice, based on the boundary protection method of information safety grade protection and principles of security domain division.
