2. High requirements for technical research and development;
In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.
Different from other malicious data tampering or hijacking attacks, DDoS is simple and crude, and can directly destroy the target. In addition, compared with other attack methods DDoS, the technical requirements and the cost of launching the attack are very low, only some server permissions need to be purchased or a batch of broilers need to be controlled, and the corresponding attack speed is very fast and the attack effect is visible. On the other hand, DDoS is easy to attack and difficult to defend. In order to ensure the needs of normal customers, service providers need to spend a lot of resources to fight against the attack initiator. These characteristics make DDoS a very good sword in the hands of hackers and a thunderbolt.

Among them, most unreliable success studies have chosen the wrong practice method. Although the slogan they shout is deliberate practice, the essence is not deliberate practice, because they do not activate long-term memory ability. For example, the number of times you play chess has no effect, and you cannot become a national player for 10 to 10,000 hours. However, if you look at the published chess scores and then speculate on the national players' playing methods, this deliberate practice method is to save SSD hard disks into the long-term memory hard disks: chunks that store the chess scores.
