Claim Text:
1. A method for securing a virtual extensible local area network (VXLAN) environment, the method comprising: configuring a default network policy on a network device for dropping all VXLAN frames comprising a VXLAN attribute, wherein the network policy is associated with a plurality of interfaces of the network device; obtaining, by the network device, a plurality of registered VXLAN tunnel endpoint (VTEP) identifiers; determining, using the plurality of registered VTEP identifiers, that a first interface of the plurality of interfaces of the network device is operatively connected to a first registered VTEP associated with a first registered VTEP identifier of the plurality of registered VTEP identifiers; disassociating the default network policy from the first interface based on the determination that the first interface is operatively connected to the first registered VTEP; receiving, at the first interface of the network device, a frame; performing a first verification that the frame is a first VXLAN frame by examining the frame to determine that the frame comprises the VXLAN attribute; performing a second verification to determine that the first VXLAN frame comprises a first registered VTEP identifier; allowing, based on the first verification and the second verification, the network device to process the first VXLAN frame; and processing, by the network device, the first VXLAN frame.
