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.

On personal computers, there are five most commonly used operating systems: DOS, Windows, Unix/Xenix, and OS/2. DOS System-In the 17 years since its inception in 1981, DOS has undergone 7 major version upgrades, from version 1.0 to version 7.0 now, continuously improving and perfecting. Windows System-Windows is the first generation of window visual interface published by Microsoft in November 1985, which makes PC enter the so-called GUI (Graphical User Interface) stage. Unix system. Unix systems were initially used on small and medium-sized computers. Unix is a multi-user system, which generally requires more than 8M of memory and a large capacity of hard disk. Linux system-Linux is the largest free software in the world at present. It is an operating system with functions comparable to UNIX and Windows and has complete network functions.
