Abstract

In this paper, the author defines an efficient formulation of a bad packet detector. This formulation specifies automated software which can update the firewall filter in real time to mitigate a distributed denial of service attack. This is particularly useful in the worst case scenario when it is not practical to trace the IP addresses, port numbers or notify Internet Service Providers (ISPs). The author assumes that attackers can't be stopped in the near term and the server must remain online to accept legitimate packets and provide needed services.
