. If the TCP serial number of the target system can be pre-calculated, whether the Blind TCP three-time handshakes with pseudo source address can be inserted or not is worth testing! In fact, the experiment I did does not explain anything. I just verified the TCP protocol serial number and the test and calculation functions. I think the author is inspired by the CC attack principle and cannot figure out the proxy method to achieve the CC
In the event of a server encounter, DDoS (Distributeddenialofservice, distributed denial of service) attack is a very good hacker behavior, it can make a large server cluster can also be a quick access failure.

1. Defensive base 1.1. How big is the attack flow?When it comes to DDoS defense, the first thing to do is to know how much of an attack has been hit. The problem seems simple, but in fact there are a lot of unknown details in it. In the case of SYN Flood, in order to increase the efficiency of sending SYN wait queues on the server, the IP header and TCP header
attacker hopes to break down the website performance bottleneck through resource-consuming attacks such as CC, thus paralyzing website services. At present, such a huge peak of 0.95 million QPS of HTTPS/ssl cc attacks, has far surpassed the performance bottleneck of most domestic protection vendors.In the end, the Alibaba Cloud security anti-DDoS system successfully defended against hacker attacks, stored a large amount of effective
