The present disclosure relates to methods, systems, and non-transitory computer readable media for generating an application protectability index for network applications and a corresponding protectability scheme. In one aspect, a method includes identifying, by a network controller, network layers associated with an application; determining, by the network controller, a corresponding security index for the application at each of the network layers to yield a plurality of security indexes, each of the plurality of security indexes providing an objective assessment of protectability of the application at a corresponding one of the network layers; determining, by the network controller, an application protectability index; and providing an application protectability scheme for protecting the application based on the application protectability index.
