DDoS attacks by WikiLeaks supporters against VISA, MasterCard, and Paypal servers made headline news globally. These DDoS attack floods are known to crash, or reduce the performance of web based applications, and reduce the number of legitimate client connections/sec. TCP SYN flood is one of the common DDoS attack, and latest operating systems have some form of protection against this attack to prevent the attack in reducing the performance of web applications, and user connections. In this paper, we evaluated the performance of the TCP-SYN attack protection provided in Microsoft’s windows server 2003. It is found that the SYN attack protection provided by the server is effective in preventing attacks only at lower loads of SYN attack traffic, however this built-in protection is found to be not effective against high intensity of SYN attack traffic. Measurement results in this paper can help network operators understand the effectiveness of built-in protection mechanism that exists in millions of Windows server 2003 against one of the most popular DDoS attacks, namely the TCP SYN attack, and help enhance security of their network by additional means.展开更多
