Energy and electric utility grids are targets for nation state-sponsored cyber attacks. With many legacy devices in power generation, transmission and distribution SCADA networks, energy networks are vulnerable. Network detection and firewalls are not strong enough to keep determined hackers out. Many DCS systms, substation automation systems, IEDs, RTUs, and controllers for turbines, generators, and compressors are vulnerable due to a lack of strong, embedded cryptographic controls, including: multi-factor authentication, secure boot, secure update, and secure, encrypted communications.
