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).　　乐团新来的第一小提琴手陈子峻是李少蓉的学弟。在学校的时候，他就苦苦追求了少蓉三年，后来因为施敬的出现，子峻不得不放弃了她，并毅然到美国求学。这次来到乐团，可以说有80%是为了重新追求心上人Some related concepts are described here first.哈利·波特（丹尼尔·雷德克里夫饰）结束了假期，即将回到霍格沃兹继续学习魔法。一个叫多比的家养小精灵警告哈利不要回到霍格沃兹，否则会陷入极大的危险。哈利没有听从多比的劝告，回到了霍格沃兹。很快，霍格沃兹发生了一连窜怪事:接二连三出现学生被石化，一直找不出原因。而哈利总能听到一种奇怪的声音，从墙壁里传出来。传说，霍格沃兹有一个密室，里面记录着伏地魔年轻时的秘密，只有斯莱特林的人才能打开密室。哈利偶然发现自己能听懂蛇说话，一时传闻是哈利打开了密室。难道多比所指的危险就隐藏在密室？
