These weapons are powerful and cruel, just like the weapons that the National Security Agency wants. Of course, the US National Security Agency does not intend to end the matter. As Ben Oni lamented to the New York Times, "If you can't catch it, it will happen under our eyes."
SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

The answer is simple: try to digest all these requests. There are 300 people coming to the 30-person restaurant, so find ways to expand the restaurant (such as renting another facade temporarily and hiring some chefs) so that 300 people can sit down, then the normal users will not be affected. For the website, it is to expand rapidly in a short period of time, providing several times or dozens of times of bandwidth to withstand heavy traffic requests. This is why cloud service providers can provide protection products because they have a large amount of redundant bandwidth that can be used to digest DDOS attacks.
