An Integrated approach to OT security | Industry 4.0

Industrial Control Systems(ICS) was designed originally to increase performance, reliability, and safety by reducing manual effort. Traditionally security was accomplished by physical isolation of OT and IT system called air gap. Today, the world is moving towards a digitalization journey, where all ICS devices connect/migrate to the Internet of Things (IoT). The fourth industrial revolution (Industry 4.0) a term, used to draw together cyber-physical systems, the Internet of Things (IoT), and the Internet of services, has started to find more resonance with OEMs, system integrators, and asset owners.

This paper describes how companies and organizations can strategize the acceleration of operational technology security in the manufacturing environment. Based on the customer interactions, we have highlighted the manufacturing challenges to be considered while selecting and implementing the security solutions, elaborated the operation strategy pillars and suggested the integrated approach with use cases to secure the manufacturing environment.
