Therefore, it is necessary to develop a detection system to make it difficult for attackers to optimize the payload. Here are three key design strategies to help achieve this.
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.
After studying the design pattern during this period of time, I still have a lot of feelings, because when I am writing code now, I often think about whether I can use any design pattern to refactor here. Therefore, after learning the design pattern, I feel that it will slowly affect the way you think about writing code. Here is a summary of the design patterns. First, all the design patterns can be sorted out. Second, an index can be made to help everyone collect.

As you can see from this, that UDP socket maximum is limit to 25 by default, but can be modified by the system attribute ("sun.net.maxDatagramSockets").
The root of driving people to do addition (efficiency optimization) and even multiplication (efficiency optimization with leverage) is actually a greedy and impetuous heart. Of course, there are geniuses in the world, but it is unwise to bet on such a small probability event as being a genius. However, people would rather pursue the dream of ignorance than think about the most essential laws and simple methods of investment.
