According to statistics, SYN attack is the most common and easily used attack method among all hacker attacks. I believe many people still remember the attack on YAHOO website in 2000. At that time, hackers used simple and effective SYN attacks. Some network worms cooperated with SYN attacks to cause greater damage. This paper introduces the basic principle, tools and detection methods of SYN attack, and comprehensively discusses the prevention technology of SYN attack.

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.
Shutter time: The smaller the shutter time, the faster the photo will be taken. However, due to the fast photo taking speed, the light may not be enough and the picture will appear very dark. 1, 2, 3 That means that the shutter time is 1 second, 2 seconds, 3 seconds, and the photographing time is getting slower and slower, which will make the light of the photo increase sharply, or even explode too much. In fact, long exposure means that the larger the shutter time, the better. It is suitable for photographing night scenes. Remember to use a tripod.
