description Disclosed are a system, method, and computer readable storage medium having instructions for applying a plurality of interconnected filters to protect a computing device from a DDoS attack. The method includes, responsive to detecting the computing device is subject to the DDoS attack, intercepting data from a network node to the computing device, determining data transmission parameters, assigning an initial danger rating to the network node, identifying a subset of the plurality of the interconnected filters which are concurrently triggered, changing the danger rating of the network node based on an application of the subset of the plurality of interconnected filters that are triggered and the data transmission parameters, and responsive to determining that the danger rating of the network node exceeds a threshold value, limiting a transmittal of data from the network node to the computing device by limiting channel capacity between the network node and the computing device.
