The main reason why DDOS attacks are difficult to defend is that there are too many vulnerabilities and attack methods that can be exploited. In the OSI seven-layer network model used in the network data transmission process, basically each layer has protocols that can be exploited by DDOS attacks. According to the different network levels of the protocols used for DDOS attacks, this paper summarizes the currently known DDOS attack types and their defense measures as shown in Table 1-3. For more detailed information on current DDOS attack and defense, please refer to Huawei DDOS attack and defense summary post.

The details that these best-selling authors skip are precisely the places where science is the most touched and is the most helpful place for people to improve themselves.

Further analysis of the formula shows that when the weapon and material attack remains unchanged, the attack with a little increase in strength is: weapon and material attack/250; When the strength remains unchanged, add a little weapon and material attack to increase the attack by 1 + (strength/250). Obviously, increasing weapons and material attacks is faster than increasing strength to increase attacks.
