Protecting Networks From Cyber Attacks and Overloading

摘要

Packets may be received by a packet security gateway. Responsive to a determination that an overload condition has occurred in one or more networks associated with the packet security gateway, a first group of packet filtering rules may be applied to at least some of the packets. Applying the first group of packet filtering rules may include allowing at least a first portion of the packets to continue toward their respective destinations. Responsive to a determination that the overload condition has been mitigated, a second group of packet filtering rules may be applied to at least some of the packets. Applying the second group of packet filtering rules may include allowing at least a second portion of the packets to continue toward their respective destinations.
