Analysis on Firewall Security Performance

As the most widely adopted security product, firewall has provided various protection functions for different aspects of network security. Based on security technology analysis on firewall, this paper evaluates its security protection performance, and analyzes the common attack means of firewall. Moreover, we detail the principles, characteristics and implementation methods of four types of firewall technologies. Meanwhile, considering the difference of firewall security performance, we summarize the security measures commonly adopted by firewall. Finally, we point out the current technical weaknesses in firewall field.
