Research on application of Dynamic Network Security Model in Campus Network

摘要

As the important infrastructure of school, it undertakes the important role of teaching, scientific research, management and foreign exchange's task campus network, its security situation directly affects if these activities can be carried out smoothly. With the rapid development of the campus network construction, the dependence of school on network is getting stronger and stronger; network security has become an increasingly important issue. This has put forward new requirements on campus network security construction. According to the actual situation of the construction in a university campus, has proposed the system safety design goal. According to the design goal has put forward the dynamic adaptive network security model RPPDRA model. According to the structure of the model, respectively from the physical layer, network layer, the application layer, operating system, safety audit and management the six aspects to make risk analysis.
