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.

Take steak as an example. I only like medium rent when eating steak, that is, it is 3-4 rare. In the past, depending on the thickness of the steak, the central temperature will reach about 50 degrees when each side is fried for 1-2 minutes. At this time, the inside of the steak will be very attractive red and the taste will not be tender. In addition, when processing some seafood products, the temperature can be fixed in the range of 70-90 degrees, thus prolonging the cooking time, thus better ensuring the taste and preserving nutrition. Finally, since the food materials in the vacuum sealed environment have little contact with air and the juice can be locked in the bag, the produced food materials will be more juicy and will not be oxidized and discolored.
