It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.有百多精兵护卫，安全上应该没有问题。　　本剧由铃木雅之、泽田镰作担任导演，杉原宪明(《贞子》)执笔剧本。家驹与成武是对出生入死的好兄弟，因在菲律宾对抗叛军游击队而失散。十多年后，家驹成为一个出色杀手，他与拍挡于利亚到汉城执行任务，目标是当地最大黑帮首脑徐氏兄弟。家驹执行任务前，认识琴师金子且互生情愫。金子有个警探男友成武，正是家驹失散十多年的好兄弟。驹与亚刺杀徐氏兄弟，过程顺利，但关键时刻，弟徐勇突然失踪。原来，整个暗杀任务竟是一个意想不到的大阴谋。
