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).而且会从沔水一带牵制的汉国，我们相当于他们潜在存在的一个盟友。Genitourinary system经历了段段波折，志颖和加恩与另外一对友人一起，在许愿树下结成情侣。加恩也渐渐得知志颖身后的秘密，感谢他因为自己而努力改变，没有理会旁人对志颖的偏见。然而，误会却总爱缠绕热恋中的人。志颖被指加害前女友，并贪走了她户口的一大笔钱。志颖被困在迷局里，别人都更认定他本质不良，而此时加恩决定将此事弄个水落石出，看自己是不是爱错了人。　　押してみると突然不思議な光に吸い込まれてしまう。刑事情报高级督察卓凯（苗侨伟 饰）现身泰国曼谷，在当地获得重要情报：九指强与泰国倪坤进行毒品交易。追查之后发现吉运帮黑吃黑将倪坤杀死与九指强进行交易。为寻找吉运帮犯罪证据卓凯与卧底潜入社团窝点后被Pak Key得力手下乐少锋（周柏豪 饰）发现行动，和他们交起手来。逃脱之后卓凯一行人准备离开泰国返回香港时发生一场大爆炸，除了卓凯之外的所有卧底葬身火海。伤心欲绝的卓凯返回香港后面临停职，变得一蹶不振。与此同时香港最大的社团长兴发生内斗，长兴新继任的龙头魏德信（陈豪 饰）以雷厉风行手段剿灭社团的高级头目，其中包括覃欢喜（许绍雄 饰）。然而覃欢喜是长期潜伏在长兴的卧底，面临此番处境，他曾想过向Handler求助调回警察队伍，但妻子突然出事惨死在社团人士手中，令覃欢喜彻底沦入黑道。219.
