The principle is that syn messages are first responded to syn_ack by DDOS protection system. With a specific sequence number (recorded as a cookie). The real client returns an ack and the Acknowledge number is cookie+1. The fake client will not respond. In this way, we can know that the clients corresponding to those IP are real and add the real client IP to the white list. The next access passes directly, while other forged syn messages are intercepted. The following is a schematic diagram of protection:?

State mode is one of the implementations of state machines, but in a "classless" language like javascript, there is no stipulation that state objects must be created from classes. On the other hand, Java Script can use delegate technology very conveniently without having one object hold another in advance. The following state machine chooses to delegate the request directly to a literal object through the Function.prototype.call method

Fire emergency
On one occasion, the chief contractor of the project had a conflict with the boss of the company and sent thugs to the construction site to prevent the construction. The boss panicked and did not know how to deal with it. "(Solving problems) is my mission." Recalling the incident, Allie's words were still full of murderous look. She found dozens of retired armed police, armed with electric batons and equipment, and the "thugs" were scared away before they started work.
The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, and any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be covered within the protection scope of the utility model.

TCP state depletion attacks attempt to consume connection state tables that exist in many infrastructure components, such as load balancers, firewalls, and application servers themselves. For example, the firewall must analyze each packet to determine whether the packet is a discrete connection, the existence of an existing connection, or the end of an existing connection. Similarly, intrusion prevention systems must track status to implement signature-based packet detection and stateful protocol analysis. These devices and other stateful devices-including the equalizer-are frequently compromised by session floods or connection attacks. For example, a Sockstress attack can quickly flood the firewall's state table by opening a socket to populate the connection table.
