Security Challenges in Industry 4.0 PLC Systems

The concept of the fourth industrial revolution assumes the integration of people and digitally controlled machines with the Internet and information technologies. At the end of 2015, more than 20 billion machines and devices were connected to the Internet, with an expected growth to half a trillion...
