SYN FLOODING

SYN flooding is a common form of attack made upon Internet connected servers with the objective of denying the service offered by the server to legitimate users. This is known as a "Denial of Serviceattack' or 'Dos'.
SYN flooding is very simple, the attacker pretends to request a connection with the target server, but uses a falseIP address. The target server, receives the request to open a connection, and responds by sending a reply to what it believes is the requesting machine and awaits the appropriate reply back, but of course in reality the target server is now trying to communicate with the falseIP address which may not exist, or at best has not sent a request and as such will not make the awaitedresponse. The target server typically waits a few minutes for the requiredresponse, so as to allow for connection difficulties through the Internet, before rejecting the requested connection. In the meantime, the attacker has been sending numerous more fake requests for connections, and the target server responds to each of them accordingly. Since a server can only satisfy a limited number of connections at any one time, during aSYN flood attack all the available connections are taken up by false requests, and legitimate requests are rejected by the server on the basis that it is too busy trying to establish other connections already.
SYN flood attacks can be difficult to detect. The establishment of a communication channel requires very little processor activity, and theattack does not cause a surge in processor activity. UnderUnix based operating systems the server administrator can check the number ofSYN communications which are pending by using the 'netstat' command, which will show the connections which are currently in a 'SYN RECEIVED' state. Under Linux, the shell command to check for SYN RECEIVED connections is 'netstat -n -ptcp
grep SYN RECV'. A large number of connections in a SYN RECEIVED state may be an indication of aSYN flood attack occurring.
Most Linux operating systems detect possibleSYN flood attacks and defend against them by checking the number of pending requests for connections, and when this queue becomes close to being full, sending aSYN cookie to the machine requesting the connection and waits for a response to the cookie before continuing to try to establish the connection. When the server sends thecookie, it clears theSYN request from its queue for connections, effectively ignoring the request. If an appropriateresponse to thecookie is received, then the connection request is re-queued and the appropriateresponse to the originalSYN request for a connection is sent as normal. UnderLinux, the operating system records possibleSYN flood attacks and itsresponse in the file /var/log/kernel which may contains data such as 'possible SYN flooding on port 80. Sending cookies' for example when a web server is under possibleattack.
