Abstract:
The present invention relates to methods, systems and apparatus for mitigating denial of service attacks. One exemplary embodiment in accordance with the invention is a method of operating a communication system including the steps of receiving at a first device packets of a first packet flow; sending, from the first device, control information to a switch through which packets of the first packet flow pass or to a control device which controls the switch, the control information including a mask corresponding to a range of expected packet values to be used for determining which packets in the first packet flow should be dropped.

Claim (Index 10):
A communications system comprising:\n a Session Border Controller, said Session Border Controller including: an Input/Output interface which receives packets of a first encrypted packet flow, each of said encrypted packets of the first encrypted packet flow including a sequence number transmitted in the clear; and a processor that controls the Session Border Controller to: monitor for a condition indicating an attack with regard to said first encrypted packet flow when said Session Border Controller is in a monitoring mode of operation with respect to the first encrypted packet flow, switch from a monitoring mode of operation to an attack mitigation mode of operation with respect to the first encrypted packet flow, said switch from a monitoring mode of operation to an attack mode of operation including:\n generating control information including a mask corresponding to a range of expected packet values, and \n sending said control information including the mask corresponding to the range of expected packet values to a switch through which packets of the first encrypted packet flow pass or to a control device which controls said switch through which said packets of the first encrypted packet flow pass.
