US official warns that there is an increase in cyber-attacks on industrial control systems

The US authorities have seen an increase in cyber-attacks that affect industrial control system networks over the past year, says the US Department of Homeland Security’s Industrial Control Systems Cyber Emergency Response Team. Industrial control systems are computers that control operations of industrial processes, from energy plants and steel mills to cookie factories. According to Reuters, the official commented that the increase in attacks was due to the fact that more control systems are directly connected to the internet.
