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.像瑞星这样的大型国企，往往它的任何一点风吹草动都会改变着一片人的命运，就在瑞星曾经的辉煌消失开始亏损的时候，那些成长在瑞星的人们的命运也发生了“改制”。Cinemax宣布续订《#反击# Strike Back》第八兼#最终季#，这部剧首季是Sky1的英剧，后来被Cinemax买了后改写风格，成为了台成名剧之一；而在15年剧终后不久，该剧以重启方式在17年复活。Shandong Province
