The term "security for operational technology (OT security)" is particularly important in the areas of Industry and Factory 4.0 as well as automation and the Internet of Things. Here, machines, sensors and control systems work closely with computers to make production processes more efficient.
OT security means protecting these technical systems against hacker attacks and faulty operation. While IT security deals with traditional computers, OT security protects machines and systems that control assembly lines, robot arms or power plants, for example. The aim is to prevent malfunctions, data theft or even dangerous production accidents.
One example: In a modern car factory, every vehicle is assembled by robots that are connected via a network. If malware gets into this system, entire production lines could fail or, in the worst case, be manipulated. Thanks to OT security, such attacks are recognised and stopped at an early stage so that production can continue to run safely and smoothly.
So if you are focussing on Industry 4.0 and automation, you should always keep an eye on the security of operating technology - to protect people, machines and data.
