Abstract:
1. A method of securing a dynamic virtualized network, the method comprising: learning, with a network automation device, a current network policy of the dynamic virtualized network by snooping multicast membership requests communicated in the dynamic virtualized network, wherein the dynamic virtualized network is a virtualized layer 2 network that is overlaid on a layer 3 physical network, the current network policy includes a first plurality of network policy elements, each of the first plurality of network policy elements identifies an authorized endpoint in the dynamic virtualized network, and the layer 3 physical network includes a plurality of network access devices; determining a network security policy for the dynamic virtualized network from the current network policy, wherein the network security policy includes one or more second network policy elements that is a different network policy element than one of the plurality of first network policy elements of the current network policy, and each of the one or more second network policy network elements adds an additional policy on how network traffic in the dynamic virtualized network is processed by a port of one of the plurality of network access devices; and applying the network security policy to each network access device of the plurality of network access devices that is affected by the network security policy.
