ABSTRACT:
Method and apparatus for deflecting connection flooding attacks. Specifically, the stateful firewall allows all connection attempts to flow into the destination host, but monitors the connection attempts to ensure that only legitimate connections are allowed. If the firewall detects that a connection is half-open for longer than a certain timer threshold, it will instruct the destination host to tear down the half-open connection, thereby freeing up resources in the destination host for other connection attempts. The timer threshold can be dynamically adjusted if a connection flooding attack is detected.
