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.

We are the builders of the future of the society, so we should use our hearts to walk out of the ivory tower and go into the society to understand the national conditions and serve the society. The social practice of "three rural areas" in summer is an effective way to let us know the society, serve the society and exercise ourselves. This social practice of "three rural areas" has enabled me to understand my social position, define my mission on my shoulders, and further stimulate my enthusiasm for learning. I deeply realize that teachers are role models for students, and our words and deeds are seen by students. Therefore, while teaching students, we should also strive to improve our comprehensive quality. At the same time, I also deeply realize that teachers should not only preach, teach and dispel doubts, but also guide students to establish correct learning attitude and correct outlook on life, world outlook and values. This summer's social practice has not only cultivated our potential to apply theory to practice and the spirit of teamwork, honed our strong will, but also realized the goal of "serving the society and exercising to become a useful person" in the process of social practice. I remember someone once said: whether a graduate is a talented person or not depends on his academic qualifications and social practical experience. Because theoretical knowledge alone is far from enough, without any potential for social practice, one cannot connect with the rapidly developing society. So there was this dragon neck trip.
