No one suspects that the firewall occupies the first place in all security device purchases. But the traditional firewall does not solve the network main security problem. The three main problems of network security today are network attacks with denial of access (DDOS) as the primary purpose, virus propagation with worm (worm) as its main representative, and content control based on spam e-mail (SPAM). These three security issues occupy more than 90% of the network security issues. And these
