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).张纪中版《西游记》以丰富瑰奇的想象描写了师徒四众在迢遥的西方途上和穷山恶水冒险斗争的历程，并将所经历的千难万险形象化为妖魔鬼怪所设置的八十一难，以动物幻化的有情的精怪生动地表现了无情的山川的险阻，并以降妖服怪歌赞了取经人排除艰难的战斗精神。”无知者无畏。亿万身家的李洪海一心想找寻不为钱而来的真爱，他意外邂逅聪明漂亮的年轻设计师夏可可，李洪海隐瞒身份与夏可可交往，两人坠入爱河并结婚，婚后李洪海才发觉夏可可早已知晓自己的身家，继而愤怒地提出离婚，但是为了公司上市，两人还要维持几个月的夫妻身份，这份跨越阶级和年龄的爱情究 竟何去何从？Approaching Science: Revealing Online DDoS Attack Platform (Part I)胡钧感觉到黎章身上传过来的炽热气息，顿时浑身一哆嗦，慌忙往后退移了一个屁股，避他简直如蛇蝎。Pretending to be "pregnant" in June, she applied to the company for maternity leave.
