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).这部戏的画面亮丽清新，除靓男俊女的主人公外，服装、场景乃至道具无不展现时尚气息。剧情的展开将跟随五个都市青年为实现各自心愿而一同自北京出发游经上海、珠海、马来西亚部分城市，终点到达加拿大的多伦多。每到一处驻足点都因种种机缘发生了一个个动人心魄的故事，爱情的情恨交加；旅途的险象环生与刺激；金钱面前人性所表露出贪梦与正义的反复、冲撞；浪漫的情感体验与现实问题间所产生的矛盾和失落感等等，细腻地刻画出一幅幅浓墨重彩的人生画卷，使全剧富有人性，充满了酸甜苦辣且耐人寻思。白起发出一声冷哼，眼中杀机一闪，天地顿时风云变幻。The Spirit of Zodiac-Pig……命运将拥有歌之力量的这两人，分别引导到了残酷的旅程上。胖子急忙大声应道：嗳。Modification Events
