When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.
The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.

If the message has been matched by the previous rule, iptables performs the corresponding action on the message, Even the latter rules match the current message, It is very likely that there will be no chance to perform corresponding actions on the message again. Take the above figure as an example, the message is first matched by the first rule, so the current message is "released", because the message has already been released, so even if the second rule in the above figure can match the message just "released", there is no chance to discard the message just now. This is how iptables works.
In addition, the war situation of the army is different, The composition of the loss varies considerably, Taking the Soviet Union during the Soviet-German War as an example, The average monthly losses of Soviet troops over the years are: In 1941, 710,000, 1942, 614,000, 1943, 655,000, 1944, 573,000 and 1945, 700,000, the difference is not too big. The ratio of 1941, which suffered the worst loss, to 1944, which suffered the least loss, is only 1.24 times. However, the proportion of dead, wounded and prisoners in the losses over the years is quite different. The average monthly number of dead and missing persons in 1941, 271,000 in 1942, 1943, 147,000 in 1944 and 186,000 in 1945 is 496,000, 3.37 times higher than that in 1945.
