Abstract
Systems and methods are provided for detecting MAC/IP spoofing attacks on networks. A method may include authenticating a network device for access to a network using a Media Access Control (MAC) address and an Internet Protocol (IP) address of the network device; wherein an attacking device is connected to the network, and to the network device, by a network hub; wherein the attacking device spoofs the MAC address and the IP address of the network device; establishing a Transport Control Protocol (TCP) connection with the network device subsequent to authenticating the network device; sending at least one TCP keepalive message to the IP address of the network device, wherein, responsive to receiving the TCP keepalive message, the attacking device transmits a TCP reset (RST) message; receiving the TCP RST message; and determining the attacking device is present in the network responsive to receiving the TCP RST message.
