The SYN flooding attack first appeared in 1996. At that time, Phrack magazine described this attack and implemented it in code [1]. This information was quickly applied to attack the mail and Telnet services of a network service provider (ISP) and caused downtime. CERT (Computer? Emergence? Response? Team) soon released a preliminary assessment and solution to this attack technology [2].First of all, let's look at Baidu's interview. So we can define a constructor first.If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.黎章，他……说得出，做得出。故事开始于第二年的“ Inspector Asagao”之后的春天，而当Asagao独自访问东北以寻找母亲的尸体时，一个新的故事就被传开了。 据悉，她面对东日本大地震和母亲的死亡深深，并且面临着东日本大地震以外的大规模灾难，而这是以前工作中无法避免的。2248年，休眠的C40小队队长方毅（任天野 饰）和他的小队成员刘火（王韬 饰）、段依山（程汉 饰演）等被人工智能控制系统长夜之光唤醒，并将执行一项绝密任务——潜入基因药物研究中心，销毁所有药物及试验资料。而研究中心已经遭到Mr.Dee（丁海峰 饰）带领的黑羽会入侵，为了获得延长休眠的权限，C40小队必须接受这场生死行动……这个叫作唐紫尘的女子告诉王超，她所练的不是平常的拳法，而是国术。
