DDoS attack is a kind of attack method based on traditional Dos attack. A single Dos attack is usually a one-to-one approach, when the target is low CPU speed, memory small or small network bandwidth, etc. performance indicators are not high, its effect is obvious.

The threat of DDoS (Denial-of-service attack) at the application level is more dangerous for data center operators. Because the state detection design of IPS devices and firewalls encounters this new attack tactic, a large increase in status requirements becomes more vulnerable, making the device itself more vulnerable to attack. In addition, the current protection measures based on boundary network have a big gap if they want to use cloud computing to solve DDoS attacks, using the DDoS infrastructure of the service provider or the dedicated DDoS attack protection in the upstream of the victim's infrastructure. The current solution is not good ...
