Traditional applications have different ports for different applications, and firewalls open different ports for different applications, as shown in the left figure. 1715-OB8DE Today’s application is transitioning to the WEB, and all different applications are hosted on the WWW port. Firewalls only need to open one port, which is the WWW (80) port, as shown in the right figure. The firewall on the left has multiple ports open, while the firewall on the right only has one port open (80), so is the firewall on the right more secure than the one on the left? Of course not, let’s imagine from another perspective that after the application is converted to WWW, the header information of each application in 1715-OB8DE has become the payload of WWW applications today. If the firewall does not have a mechanism for deep packet detection, the transformation of the application to WEB will lead to the firewall becoming meaningless. According to GARTNER’s prediction, if the firewall is still limited to state detection and does not have a mechanism for deep packet detection, it will soon face the fate of elimination.
