How can industrial companies implement the concept of Industry 4.0 without putting IT security at risk? Seven steps can be taken to build a secure “Smart Factory”: 1. connect machines and systems through secure IoT gateways; 2. secure and remotely access all devices; 3. centrally orchestrate and manage devices, users, and processes; 4. collect data from machines and IoT gateways; 5. monitor the infrastructure; 6. analyze the collected data; 7. integrate edge computing. Welcome to Industry 4.0.
