Chapter IV Fire Protection Technical Service Activities
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.

If we start from the initial registration, less than 2% of the people will actually become pilots. These people are also very good in terms of physical condition, but in the end most of them cannot fulfill their dream of flying, which shows the strict standards. Those who barely passed the preliminary examination with minor defects will almost certainly be eliminated after entering the school. So I once again advise you to give up, although this advice is a bit cruel. According to my personal experience, it is better to give up at the beginning than to be eliminated at the last moment after hard work. It's better to have short sharp pains than long dull pains!
