Compare the firewall of mobile software server with the advanced anti DDoS CDN

Initial stage: many server managers immediately install a mobile software server firewall when the server is attacked. In fact, that effect is not too great, because it has already reached the network layer of the server. In any case, the traffic has long been to the network port of the server. For example, once the attacker increases the traffic, the network bandwidth will be consumed, of course, all will hang up.
For the early two years, the effect of small attack traffic is very obvious, and the advantage is low cost. Maybe a few hundred yuan can solve the difficulty. Nowadays, times are different. For no reason, dozens of G and hundreds of G attacks are everywhere.
Wudxcdn has a feature of cloud intelligent security protection. A session web page pops up at the CDN node. Visitors click to confirm to browse normally and add CDN authorization management, which is not easy to happen again. The device is not easy to click the button, and cannot open to the source server. All data information is stored without connection. Therefore, the attack fails.
They also play a leading role in the industry.
Advanced anti DDoS CDN uses the connection layer and its link layer + network layer to solve the difficulties, which is more suitable for today's large traffic attacks. After the attacker attacks, the traffic will be immediately connected to the advanced anti DDoS hardware firewall. The cluster server firewall will have considered more than 99% of the attack application, and there are still a large number of CC, which may not be able to be completely considered.
When the CC traffic reaches the CDN node server, the IP that fails to be blocked is completed according to the limited browsing frequency and other CC prevention countermeasures.
