Compared with SYN cache method, SYN? Cookies technology does not need to allocate space at all when receiving a SYN. Because the most basic data that make up the connection state are encoded and compressed into the sequence number bits of SYN-ACK. For a legitimate connection, the server will receive an ACK message segment with a serial number (actually the serial number has been added by 1), then the basic TCB data will be regenerated, and a complete TCB will confirm that the data will be safely instantiated through decompression. This decompression can be successful even under severe attacks, because there is no storage load at all on the host side, only the load that calculates the encoded data into the ACK sequence number. The disadvantage is that not all TCB data can be added to the 32-bit sequence number segment, so some TCP options required for high performance cannot be encoded. Another problem is that such SYN-ACK message segments will not be forwarded (because forwarding requires complete state data).
Besides personalization, it refers to making targeted operations according to the different situations of individual users. The situation of users can be divided into life cycle and characteristics according to the above figure.
DDoS attacks can be divided into many different forms. These forms include flood attacks and more sophisticated application layer attack methods/tools. Flood attacks rely on a large amount of traffic/sessions to deplete a target, such as TCP SYN, ICMP, and UDP floods; Advanced application layer attack methods/tools include Slowloris, KillApache, etc.

At that time, after the last shelling ended, I looked down with my telescope in my hand, There were fragmented bodies everywhere, covering almost the entire width of the position, and when the wind blew, there was a particularly heavy smell of blood. I remember the wind direction at that time very clearly because of the smell: even if we were in the upper air outlet, the wind blew up against the land, and the smell was also brought up by the gust of wind.
Some recent systems basically default to 1024 bytes of backlog size, but many servers on the network configure it to 128 bytes or less. Usually, the time threshold for retransmitting SYN-ACK is 5 seconds, which is twice the normal successful reception time. The default timeout time is 3 seconds, and the time from the first SYN-ACK to its TCB being recovered is 189 seconds.
