Smart power grid technology may be prone to hacking:
Smart grid technology -such as management systems in power plants -may be prone to hacking, say scientists who delved into “nightmare“ scenarios where hackers exploit security weaknesses and execute a disruptive plan of cyberattacks. Reliability measures of electrical grid has risen to a new norm as it involves physical security and cybersecurity. Threats to either can trigger instability, leading to blackouts and economic losses.
