LINUX: Linux uses the variable tcp_max_syn_backlog to define the maximum half number of connections that the backlog queue can hold. In Redhat 7.3, the value of this variable defaults to 256, which is far from enough. A low-intensity SYN attack can fill up the half-connection queue. We can modify the value of this variable with the following command:
On the other hand, although DDoS can erode bandwidth or resources and force service interruption, this is far from the real purpose of hackers. As the saying goes, there is no killing without buying and selling. DDoS is only a nuclear weapon in the hands of hackers. Their purpose is either extortion, commercial competition or political stance. Driven by this kind of black interest, more and more people take part in this industry and improve and upgrade the attack methods, resulting in DDoS becoming more and more fierce in the Internet industry and becoming a persistent disease that cannot be overcome worldwide.

In the case of a reflection attack, An attacker uses a controlled host to send a large number of packets, What makes these packets special is that, The destination IP address points to the server, router, and other facilities that act as reflectors, while the source IP address is forged as the target IP address, When the reflector receives the data packet, it will think whether the data packet is requested by the attack target, so it will send the corresponding data to the attack target. When a large number of response data packets flock to the attack target, it will deplete the network broadband resources of the target, resulting in denial of service attacks.
