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.During Tmall 618, the drainage effect on Osaka Weaving House Line was obvious.From the reasons why parents choose to cultivate their thinking ability and the results they hope to achieve, it can be found that parents want their children to accept the needs of cultivating their thinking ability, but they do not have high requirements for learning.
