A method and system for securing a VXLAN environment, including configuring a default network policy, associated with interfaces of the network device, for dropping all VXLAN frames including a VXLAN attribute; obtaining, by the network device, registered VTEP identifiers; determining, using the registered VTEP identifiers, that an interface of the network device is operatively connected to a registered VTEP associated with a registered VTEP identifier; disassociating the default network policy from the interface based on the determination; receiving, at the interface, a frame; performing a first verification that the frame is a VXLAN frame by examining the frame to determine that the frame includes the VXLAN attribute; performing a second verification to determine that the VXLAN frame includes a registered VTEP identifier; allowing, based on the first verification and the second verification, the network device to process the VXLAN frame; and processing the VXLAN frame.
