The security of the computer network has already become the important component in the country and national defense, and intrusion detection technology is one of the key technologies of guaranteeing computer network safety.
According to National power secondary system safety protective general scheme (the seventh version),this paper primarily analyzes the feasibility and reasonableness of computer network safety protective scheme from the aspects of system analysis,construction and assessment of building computer network safety protective system in power plant.
The various kinds of factors that security of computer network was threatened are analysed,the basic component of system of network security are dissected The tactics and methods of security of network system have been put forward in this paper
This text has analyzed various kinds of factors threatening the safety of computer network,as well as the basic composition of the security system of network, and proposed the tactics and implementing scheme for the safety of network system.
Concerning the safety of computer network, this article focuses on the most threatening factors to computer network at present, and proposes corresponding measures of protecting the network. The classification of network safety is presented as well.
