Although technologies that can effectively combat SYN flooding already exist, there is no standard remedy for TCP implementation. You can find different implementations of different solutions to protect the application layer and network layer in today's operating systems and devices. This paper describes this attack in detail and looks forward to and evaluates the anti-SYN flooding methods currently applied to end hosts and network devices.I think the first post in life should be such as opening and stealing so-and-so, deep stealing XX, etc. However, I, Gai Xiaobang, have a dream of having a wife who talks at night, so I have this post.Late July or early AugustAlthough this kind of attack has appeared for 14 years, its variants can still be seen today.
