A SYN Flood Variation Attack Detection Model in Botnet

僵尸网络中的变种 SYN Flood攻击检测模型

When a new TCP connection comes in from a client by means of a packet with the SYN bit set the server creates an entry for the half-open connection and responds with a SYN-ACK packet .

当从客户机发来新的TCP连接时，数据包设置了 SYN位，服务器就为这个半开的连接创建一个条目，并用一个SYN-ACK数据包进行响应。

Enough SYN requests to the system and an attacker can use all the connections on a system so that nothing else can get through .

只要针对系统的 SYN请求足够多，攻击者就能够使用系统上的所有连接，从而阻止任何东西通过。

The problem that can occur with TCP is when a rogue client forges an IP packet with a bogus source address then floods a server with TCP SYN packets .

当恶意客户机使用虚假的源地址来伪造一个IP报文时，TCP就会出现问题了，这会大量TCP SYN报文 攻击服务器。

The interface on the destination ( the server ) receives the incoming SYN packet places it on the ipintrq queue and raises a software interrupt .

目的地（服务器）上的接口接收传入 SYN包，将其放在ipintrq队列中，并引发软件中断。

When the client issues connect the tcp_output () function is called at the protocol layer which outputs the SYN packet onto the interface .

当客户端发布connect时，在协议层调用tcpoutput（）函数，将 SYN包输出到接口。

For example the initial SYN request can be a gold mine ( as can the reply to it ) . RST packets also have some interesting features that can be used for identification .

例如，初始化的 SYN请求是一个金矿（ 以为这个 SYN请求是要回复的），RST信息包也具有一些比较有趣的特征用来鉴别系统）。

The address and port to which these original SYNs are sent is determined through port prediction .

地址和端口指向那些最初的 SYN 包 发 向的通过端口预指定的 地方。
