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.

If cyber war is still a wild west, it is obvious that citizens will become victims. Our culture, economy, education, health care, livelihood and communication are closely connected with the Internet. If an enemy country wants to use more "traditional" attack methods (perhaps terrorist bomb attacks or the release of a chemical agent) to play the greatest role, Why not start with blackmail software attacks, freeze people's bank accounts, close hospitals, make people unable to contact emergency workers, and ensure that people cannot communicate with their families during an inevitable period of chaos?

Tong, no unit or individual is allowed to occupy the fire exits to build houses, pile things and set up stalls. The existing flammable building intensive areas in cities and towns should be gradually transformed in combination with the overall planning of cities and towns, and contiguous transformation can be carried out if conditions permit. Fire lanes are generally not allowed to park other vehicles, and residents should be discouraged from building illegal buildings and piling up articles. 3. Requirements for setting up fire lanes in factories, warehouses, storage yards, storage tank areas and large public buildings According to the reflection of each fire fighting squadron in fire fighting practice, When a fire occurs in a large area of factories, warehouses, storage yards and storage tank areas, the fire burns very fast, the fire is fierce, and the fire fighting lasts for a long time. If there is no fire ring lane and flat open space, it will inevitably cause fire vehicles to be unable to enter or leave, which will inevitably cause blockage and make it difficult for fire engines to approach the fire site. Therefore, fire lanes should be set up in factories and warehouses. When a Class a, Class B and Class C factory building occupies an area of more than 3000 square meters or a Class B and Class C warehouse occupies an area of more than 1500 square meters, a flat open space with a width of not less than 6m for fire engines to pass through can be set up along its two long sides. Open yard area for flammable and combustible materials, Liquefied gas storage tank area, For Class a, Class B and Class C liquid storage tank areas, there shall be large public buildings such as fire lanes or flat gymnasiums with a width of not less than 6m and a space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters that can be passed through by fire engines. Because of the large volume, large floor area and large and dense personnel, in order to cause fire, there shall be large public buildings such as the gymnasiums with a flat space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters.
