Amplification attack is a special reflection attack. The special feature is that the reflector has the function of amplifying network traffic and is a common technical means in DDoS. Its basic principle is relatively simple. For a C/S service, if the Server-to-Client Response message is larger than the Client-to-Server Request message, the traffic is enlarged. In order to use amplification technology in DDoS, one condition needs to be met, that is, the services provided by Server are based on connectionless protocols such as UDP.
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.

"I remember we had a very clear division of tactics at that time, First, adjust all the automatic rifles in hand to semi-automatic shooting mode, Of the 15 men, apart from the gunners and the bazookas, Most of the others use '81 bars', There are also a small number of 63 types, I'm using the 63, One of the characteristics of this gun and the 81-bar is that the single shot accuracy is especially good, Even better than '56 and a half', Much better than 56 Chong and some Mao Zi guns captured from the Vietnamese, At that time, in order to give full play to this advantage in precision, The company commander ordered us to use this tactic, The concrete implementation is to use heavy machine guns to suppress fire in hidden places, In addition to killing as many enemies as possible, If the enemy takes tactical actions such as lying down to avoid shooting, Then use machine gun fire to limit its movement range, That is to say, they are suppressed in situ, and then rifles are used to give full play to the advantage of high semi-automatic shooting accuracy, giving them "roll call" one shot at a time. This tactic is still very effective in dealing with the first and second large-scale attacks, with extremely high efficiency, and almost all the Vietnamese troops who came up were killed on the way to attack.
