Gartner defines OT security as, “Practices and technologies used to (a) protect people, assets, and information, (b) monitor and/or control physical devices, processes and events, and (c) initiate state changes to enterprise OT systems.”. This field of security emerged when OT systems became connected to the internet which made them more prone to online threats and external attacks. OT security solutions cover a wide range of technologies such as next-generation firewalls (NGFWs), as well as security information and event management (SIEM) systems, and many more.
