Industrial Cybersecurity Resources for Safer Industrial Network Operations
Industrial cybersecurity is the practice of protecting industrial systems, operational technology (OT), industrial control systems (ICS), supervisory control and data acquisition (SCADA) environments, and connected industrial networks from cyber threats. It focuses on maintaining the confidentiality, integrity, and availability of systems that support manufacturing, energy production, transportation, utilities, and other critical operations.
As industrial organizations adopt digital transformation, Industrial Internet of Things (IIoT), cloud connectivity, and smart automation, cybersecurity has become a critical requirement. Industrial cybersecurity helps maintain operational continuity, protect sensitive data, prevent equipment disruptions, and reduce safety risks caused by cyber incidents.
