The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.

According to Microsoft statistics, the upper limit of dynamic domain name queries that a DNS server can withstand is 9,000 requests per second. However, we know that tens of thousands of domain name resolution requests per second can be easily constructed on a P3 PC, which is enough to paralyze a DNS server with extremely high hardware configuration, thus showing the vulnerability of the DNS server. At present, the most commonly used DNS server software is the leading WINMYDNS in China and Bind abroad.
