Security Analysis And Solution Design Of A University’s Campus Network

With the development and popularization of Internet, informatization and digitization construction in colleges and universities are also developing rapidly. As an important infrastructure in information and digital campus, the campus network plays a fundamental role in the teaching and scientific research, management and external exchange, and it provides a good guarantee for school’s education teaching. Currently, the campus network has spread to all departments of the school and becomes the basic equipment of the entire campus. The school’s demand for network management and security has grown, so the construction of a reasonable system of network security is particularly important. Safe campus network will promote the teaching and academic exchange environment, most importantly, the construction of the campus network security is related to the future and development of the school. The construction of a safe and reliable campus network can not only use the existing resources of the school reasonably, safely and effectively but also can improve the network working environment to facilitate the management and maintenance and improve the reliability of the network.So the main research work of this paper includes: first, doing a comprehensive analysis of the campus network security situation and the needs of the campus network security on the basis of the design of the network security of a university’s campus network project. Second,doing an in-depth study on the campus network security architecture and analyzing a variety of common network security technologies according to the analysis of the security problem. Third,on the basis of the APPDRR dynamic security model and the Cisco SAFE architecture,dividing the campus network into a variety of functional regional modules, and deploying corresponding solutions in the regional module to solve the campus network security problem and relieve the campus network attacks. The whole design idea, solutions and technology of this paper have a certain reference value for the construction and transformation of the current campus network of the vast majority of colleges and universities.
