Reactive network security for a building automation system

Abstract

A method provides reactive network security of a building automation system that includes a controller and a network of electronic devices connected in electronic communication. The method includes monitoring, by the controller, external electronic communications received by the network. The monitoring includes comparing, by the controller, a traffic property of the external electronic communications to a corresponding baseline traffic property. The method also includes instituting a traffic communication protocol based on said comparison. Said instituting of the traffic communication protocol causes one or more of restricting of type of incoming external electronic communication to the network, using a virtual private network to communicate within the network, and encrypting of the electronic communication within the network. A building automation system includes a controller, a plurality of electronic devices, and a network. The plurality of electronic devices and the controller are in electronic communication via the network.
