Attack | difference For readers: DDoS researcher, major webmaster, network administratorPre-Knowledge: ASP Basic reading abilityMany friends know the barrel theory, the maximum capacity of a bucket of water is not determined by its highest place, but by its lowest place, the server is the same, the security of the server is determined by its weakest point, and the most vulnerable places are more dangerous than the server.
Comments: A DDoS attack uses a group of controlled machines to initiate an attack on a single machine. Such a rapid attack is hard to guard against, so it is highly destructive. If the network administrator can filter IP addresses Against Dos in the past, there is no way to face the current DDoS many spoofed addresses. Therefore, it is more difficult to prevent DDoS

Suitable for readers: DDOS researchers, webmasters, and network administratorsPrerequisites: Basic ASP Reading Capability Many of my friends know the bucket theory. The maximum capacity of a bucket is determined not by its highest capacity, but by its lowest capacity. The same is true for servers, the security of a server is also determined by its most vulnerable aspect. The most vulnerable aspect is how dangerous a server is. The same is true for

increasing the memory and modifying the number of maximum file descriptors (FD). So the question is, how is the DDoS attack going? Number of TCP semi-connections for DDoS attacks In a DDoS attack, if the server allows a large number of TCP connections, server memory is very large, then the attacker is often to send a large number of TCP semi-con
