Abstract
In a network system in which a server receives packets each including a source address, and in which the server ordinarily responds to each packet, Distributed Denial of Service attacks may be launched by malicious actors controlling a plurality of network devices. In such an attack, the attacking devices may spoof the IP address of a legitimate device, e.g., they may include, in each packet, the source address of the legitimate device. As such, systems and methods for increased security using client address manipulation are provided.
