Industria 4.0, or Industry 4.0, is a model of industrial digitization that connects machinery, sensors, and software so equipment can collect and exchange operational data. It commonly includes automation, industrial networks, and data analysis to improve production, maintenance, or quality control.
For cybersecurity, connectivity creates more points that must be protected: industrial devices, data pipelines, user accounts, and links to suppliers or cloud services. In real deployments, attackers may exploit weak access controls or unpatched equipment to disrupt operations or access data. Defenses include inventorying connected assets, limiting permissions, controlling updates, monitoring network activity, and ensuring people oversee systems that affect production. Reliable data and clear process controls also matter when connected-factory data is later used by AI.
