OT and Industrial Security

OT and Industrial Security is a practical 53-page PDF book from oJAYo.com. Protecting the systems that run factories, utilities and infrastructure.

Operational technology (OT) is the hardware and software that monitors and controls physical processes: power grids, water treatment, oil and gas pipelines, factories, building systems, hospitals’ equipment and transport. When OT is attacked, the result is not just lost data; it can be stopped production, damaged equipment, environmental harm or danger to people.

OT security has become one of the most important areas in cybersecurity. Ransomware increasingly disrupts industrial operations, and state-sponsored groups have been found positioning themselves inside critical infrastructure.
