The energy industry has become the second most prone to cyber security attacks with nearly three-quarters of U.S. oil & gas companies experiencing at least one cyber incident. Remote cyber attacks on oil and gas refining & production can result in severe consequences to human and environmental safety in the form of ruptures, explosions, fires, releases, and spills. In addition, disruption of service and deliverability can be devastating for key infrastructure end users such as power plants, airports or national defense.
