Hunan Railway Professional Technical College Campus Network Security System Research And Implementation

With the continuous development of the campus network construction, the school of campus network is more and more strong, the dependence of the school campus becomes an important part of the construction of informatization, and campus network security situation will directly affect the school activities. Because of safety awareness and management, and other aspects of reason, various security problems emerge in endlessly, resulting in campus network faced huge security threats. Studying and exploring the campus network security status, technologies and trends, and to ensure orderly school activities to promote the construction of the school of information of great significance.Campus network increasing subscribers and rising unsafe factors form bright contrast. This paper based on this pair of contradictions to study the campus network security system and security strategy. This paper studies the main content as follows:1.This paper expatiates the contents of network security and guard system research. And in the light of campus network security threats and produce facing major, this paper analyzes the causes of network security system preventive strategy.2.In hunan railway Professional technical college campus network current network security situation and the security system structure makes a detailed analysis, found that there security threats.3. In hunan railway Professional technical college campus in recent years some existing problems and the actual needs of the campus network construction, from the campus net exports, core layer, distribution layer, the access layer, server group and safety management, etc., and gives the omni-directional safety system solutions. With an emphasis on the core of redundancy and load balance in our campus design, solve the existing single-point fault.In order to further strengthen of campus network safe protection, establishing multi-layer, three-dimensional, intelligent security defense system, each security incident, abnormal flow testing, safety equipment and automatic defense combined functions, in the whole campus network security linkage defense system implementation, and makes a verification and testing, and good results have been achieved.
