In the defense measures against DDOS attacks, deployment strategy is also a part that needs to be seriously considered. At present, the more reasonable deployment strategy is: the detection equipment is deployed close to the business host, the source is cleaned, and the bypass deployment is carried out. Attacks are distributed, and defense also needs to consider distributed deployment strategies.敢问经费人力到位，沥海一月可产多少支？杨长帆不假思索道：统统到位的话，月产千支不在话下。CBS于2012年3月14日宣布续订第四季。Female workers during pregnancy and lactation also have the right to refuse to engage in operations where the concentration of toxic substances exceeds the national occupational health standards.

However, SYN flooding is very different from other TCP spoofing attacks. SYN flooding attacks the services of the new connection without affecting the established connection, while other spoofing attacks break the established connection and cannot block the new connection from the beginning. SYN attacks can be stopped only by modifying the initial handshake program, while other spoofing attacks require checking every piece of data throughout the connection life cycle. What SYN flooding and other TCP spoofing attacks have in common is that they all depend on the attacker's ability to send IP packets that disguise the source address, while the same way to defend them is to deploy more address filtering or use IP Security Protocol (IPsec).
