Design and Application of Network Security System

With the development of information technology, the computer networks has involved deeply into the scientific, cultural, and economic and defense fields, made progress in society. However, this development has also brought some negative effects, the openness of the network increases vulnerabi/ity and complexity of network security, the sharing and distributed processing of information resources also increased the possibility of network attacks. The network security has become more and more important. This paper analyzes the reasons causing the insecurity of the network,and puts forward some simple countermeasures for the network maintenance.
