When the incident occurs, the incident will begin to spread. Why should it be spread? Because the event source itself does not have the ability to handle the event. For example, when we click one, a click event will be generated, but the button itself cannot handle the event (nonsense). The event must be propagated from the button to reach the code that can handle the event (for example, we give the onclick attribute of the button the name of a function, that is, let the function handle the click event of the button).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.李玉娘和嬴子夜一道扶着绿萝。Kargil Girl is based on the life of Gunjan Saxena, an Indian Air Force Pilot.
