Cyber security of Critical Infrastructure (CI) is a serious and ongoing challenge that affects electricity, gas and water, production and distribution networks up to a regional scale. The significance of cyber-physical infrastructure security substantially differs from cyber security in general, because of the implications imposed by the topology configuration that obeys specific laws of physics.
analysis of energy distribution infrastructure is done in conjunction with application security in power systems to prevent, mitigate, and tolerate cyber-attacks. Currently, Energy Infrastructures use common and standardized communication protocols for bi-directional communication, including 5G and Internet protocols. In new scenario, previously unknown networked agents can
interact with remote nodes of critical infrastructure. This fact has substantially changed the perception of cyber infrastructure security aspects in all business scenarios, including the metering one. As an effect, utility companies in general - and energy utilities specifically - require better safety measures, improved security, and highly reliable data protection.
