Title: SYSTEMS AND METHODS FOR IP SOURCE ADDRESS SPOOF DETECTION
Abstract:
Aspects of the present disclosure involve systems, methods, computer program products, and the like, for detecting a spoofed source IP address on an incoming communication to any type of network, such as a telecommunications or content delivery network. Each interface to the network may include a classifier that defines or describes source IP addresses that are recognized by the interface as a valid source IP address. If a received communication packet includes a source IP address that is not included or defined by the interface classifier, the packet is considered as a possible spoofed IP address and one or more mitigation techniques may be applied to the incoming packet to prevent an attack on a device or network utilizing the spoofed packet. Such techniques may lessen or prevent an unauthorized access of the device or network or a DDOS attack on the network or device.
