Both these attacks and SYN flooding target the victim's TCP application and can interrupt the victim's service at much less cost than brute force flooding packet methods. 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).她只比香荽大几个月。改革开放初期，国家政策调整，计算机研究所进行变革。研究员张镇南萌生了开公司的想法，公司创立的过程极其艰辛。张镇南看准时机，领导研发了汉卡，随后与P&P公司合作进一步增强了公司的实力。在独立扛起国产电脑大旗之后，他们面对国内外众多集团品牌的激烈竞争，此时张镇南却又不得不和往日战友对簿公堂。然而，任何困难都挡不住张镇南想要走上更大舞台的决心，收购国际计算机业巨头P&P之后，张镇南和他的天驰公司站到了世界电子业的顶峰。这是一个男人从大城市生活中恢复过来的故事。但当他必须为他认为应该得到的东西而奋斗时，这就不那么容易了。他必须通过这场农业挑战才能夺回它。他的朋友和家人都在那里帮助他。不知何故，他没有意识到这一点，反而得到了一些更有价值的东西。
