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 20):
A non-transistory computer readable medium including a first set of computer executable instructions which when executed by a processor of a first device cause the first device to perform the steps of:\n receiving packets of a first encrypted packet flow to monitor for a condition indicating an attack, each of said encrypted packets of the first encrypted packet flow including a sequence number transmitted in the clear; 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 the monitoring mode of operation to the 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.
