Dependent enhancement of management of computer applications, computer applications on the network-dependent enhancement. Computer networks have been expanding, increasingly complex network structure. Information security should be done as a whole to consider, comprehensive coverage of the various levels of information systems for networks, systems, applications, data, comprehensive prevention. Information security system model shows that security is a dynamic process, before, during and after the technical means should be complete, and safety management through the activities of security always. Network security issues along with the generation of the network can be said that the network where the network security risks. Such as infected by viruses and hacker attacks, network security events, mainly through the network, and almost all the time in the event throughout the world. In addition, like malicious software attacks, unauthorized access and operation of the user, the unlawful interception of user messages, and changes are common safety facts. Harm network security incidents, I believe each of us computer users are more or less know at: ranging from the computer system is not functio
