Here are three key design strategies to help achieve this.SYN attack is a kind of DOS attack. 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.《龙岭迷窟之最后的搬山道人》是首部探险动作互动剧，故事讲述了搬山魁首鹧鸪哨在经历湘阴瓶山寻珠的挫败后，通过胡八一的祖父胡国华，找到“摸金校尉”了尘大师，并在了尘的帮助下勇闯西夏黑水城，寻找传说的雮尘珠来破解族人千年来的诅咒，展开了一场“逆天改命”和“宿命”之间的博弈，互动剧中加入分支选项、动作模拟、QTE等多种互动玩法，共有6个支线结局，单线体验60分钟，总体验时长121分钟。
