The real cyber security threats lie in the critical infrastructure sector. Currently the Energy and power sector is facing critical cyber security challenges. Emergency services, water treatment plants, traffic management, and other critical infrastructure rely on operational technology solutions to operate correctly. Operational technology (OT) uses hardware and software to manage industrial equipment and systems in the energy, industrial, manufacturing, oil and gas, robotics, telecommunications, waste control, and water control industries. Cybersecurity is vital to OT systems to protect critical infrastructure. Any momentary delay or period of unplanned downtime can cause manufacturing plants, power plants, or water supply systems to shut down.
