What is OT Security and Why It Matters

Operational Technology (OT) security focuses on safeguarding the hardware and software systems that drive physical processes in industries like manufacturing, energy, and transportation. These systems include programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, and distributed control systems (DCS) – all of which are essential for keeping critical infrastructure running smoothly.

The importance of OT security is hard to overstate. In 2023, cyberattacks targeting critical infrastructure surged by 30% ^[2], with a staggering 140% increase in attacks that caused physical damage ^[3]. By 2024, 33% of organizations reported experiencing six or more OT security breaches – up sharply from just 11% the year before ^[4]. These attacks are now considered among the top five global risks ^[1].

How OT Security Differs from IT Security

IT security and OT security serve very different purposes. While IT security is all about protecting data and communication networks, OT security focuses on keeping systems operational and ensuring physical safety. The stakes are much higher in OT environments – where a system failure could lead to injuries or disrupt vital services.

Feature	IT Security	OT Security
Primary Focus	Protecting data and confidentiality	Ensuring system availability and safety
Downtime Tolerance	Minutes to hours acceptable	Even seconds can be critical
System Updates	Frequent updates and patches	Updates carefully planned to avoid disruptions
Network Protocols	Standard internet protocols (TCP/IP, HTTP)	Industrial protocols (Modbus, DNP3, IEC 61850)

OT systems come with challenges that IT professionals don’t typically face. Many run on outdated hardware and software, making quick updates nearly impossible. For example, updating a power plant system might take hours or even days. Additionally, the rise of the Industrial Internet of Things (IIoT) has blurred the lines between IT and OT, creating new vulnerabilities by merging IT risks with the unique constraints of OT environments.

Critical Infrastructure Sectors Using OT Security

OT security plays a vital role across numerous industries, especially those that underpin public safety and essential services. Here are some key sectors where OT security is indispensable:
