Abstract
A method for addressing attacks on a computer connected to a network includes receiving at a router a TCP SYN request to be screened. The method also includes comparing the received TCP SYN request to be screened to at least one stored tuple representative of one or more SYN requests previously received at the router and determining that the received TCP SYN request to be screened matches the stored tuple. In response to determining that the received TCP SYN request to be screened matches the stored tuple, the TCP SYN+ACK response is prevented from being sent by the router in response to the TCP SYN request to be screened.
