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.
4: Fake goods, some packaging with hangers, NBA and Stance logo are slightly larger than the genuine goods, the color of the hangers is similar, and the font is slightly different. However, no matter what kind of goods, channel goods or company goods, the black-and-white ordinary version will have round anti-counterfeiting labels, and there is no fake one! The toe material is even more horrible and completely inconsistent. It is really black and deep snowflake ash, really white and light snowflake ash, and you can see the fake picture below. After all, there are 5 or 6 different materials woven together for real socks, and it is already very good to use 4 kinds of fake socks. I am only a few students, and the team version will not be able to identify them. However, the materials are obviously different when making goods, which cost about 10 yuan. I suggest you be careful.
