Research on the protection strategy of network security

The global information has become the human development trend with the development of network technology. People enjoy the convenience brought by the network technology and confront many network security issues. Because the network attack behavior has concealment, complexity and permeability, the network security issues become increasingly prominent and the network security protection become more difficult. Based on the analysis of the threatening factors to the network security, such as hacking, computer viruses, computer system vulnerabilities, security issues of the network protocol, weak authentication and logic bombs, the firewall technology, intrusion detection technology, access control technology and computer virus protection technology are proposed to ensure safe and stable operation and use of network.
