The Research And Design About The Bank Core Network Security Protection System According To The Classified Protection

As China speeds up its process of social networking in all fronts, the dependence of national economy and social development on the fundamental information networks and critical information systems becomes significant. Therefore, information security draws more and more attention from IT professionals. As an essential part of basic Information Security system, Information Security Class Protect plays a very important role in protecting the security of fundamental information systems in government and company. Classification protection system for Information security is an important aspect of national information security, and a political task for national security and social stability. However, Information Security Class Protect in China is only in its primary stage of development, without valid models or tools readily available in this area. Therefore Classification protection is a great demand for the current situation of information security.This research paper firstly introduces the Network security situations at home and abroad, and researches the policy of the Classification protection system carried out in our country so far. The key point is the basic requirement of network security in Classification protection. Through making a research on its relevant regulations and requirements, the writer makes a reasonable security goal according to a detailed requirement analysis of Information Security Class Protect and the fundamental situation of the bank core network system such as network structure, system composition, service mode, etc.Secondly, the analysis of security risk and proactive requirements is made on the basis of the third level requirement of the classified protection and gradational security. The core network operating system is reasonably divided into several security areas based on its different service function and network position. According to the security area of different security needs and classified protection requirement, the security areas should be designed in personalized safety design, by "points area, delaminating, deep protection" as the design idea.At last, according to the security area of different security needs and classified protection requirement, a generic and practical security protection system including frame structure, safety strategies, system deployment, etc is designed upon guidance of thoughts and strategies. Meanwhile, the dissertation introduces overall network model and makes detailed analysis and research of the corresponding applied technology and products. It has the systematic and practical advantages because it considers the whole system security problems in all aspects of the overall system, so the writer hopes it could be a model reference for the banks that have similar security needs as the solution design.
