Abstract
Several methods are disclosed for detecting and mitigating Distributed Denial-of-Service (DDoS) attacks that are intended to exhaust network resources. The methods use DDoS mitigation devices to detect DDoS attacks using operationally based thresholds. The methods also keep track of ongoing attacks, have an understanding of “protected IP space,” and activate appropriate mitigation tactics based on the severity of the attack and the capabilities of the DDoS mitigation devices.
