Study of campus network security based on SAPPDRR model

Taking network security system APPDRR and SAPPDRR model of the whole network as theoretical guidance, this thesis analyzes security risks faced by campus network completely and in full detail, combining with the network system features. The current mainstream of network security technologies such as firewalls, intrusion detection, virtual private network (VPN), certification, and others are carefully studied to illustrate security technologies which shall be focused for the campus network security. Then, taking the Jiangxi Institute of Education campus network as an example, the specific characteristics of campus network are considered to analyze the reality of network security and to design campus network security solutions, which have strong relevance and feasibility.
