一种SYN Flood DoS攻击工具的实现

为检测目标主机是否存在DoS漏洞及承受DoS攻击的能力，在Linux平台上实现一个基于SYN Flood的DoS攻击工具。首先，介绍SYN Flood攻击原理。然后利用原始套接字结合IP欺骗技术，实现SYN Flood攻击报文的构造和发送，实现了基于SYN Flood攻击工具synAttacker。最后，利用synAttacker进行测试，并对测试结果进行分析。测试结果表明synAttacker能够进行有效的SYN Flood攻击，可以作为DoS渗透攻击工具。

An Implementation of DoS Attack Tool based on SYN Flood

In order to detect the DoS vulnerability and assess the DoS attack-withstanding ability of target machine, a SYN Flood-based attack tool is implemented on Linux. The principle of SYN Flood attack is discussed in this paper, and meanwhile a SYN Flood-based attack tool called synAttacker is realized by using IP spoofing and raw socket. Finally, test on SYN Flood attack with synAttacker is done, and the test results indicate that synAttacker is fairly effective in SYN Flood attack and can be used as a DoS attacking tool.
