What Is OT Security and Why Is It Important in Cybersecurity?

Operational Technology (OT) security protects the systems that control industrial operations – spanning manufacturing, robotics, energy grids, and critical infrastructure. Because OT directly manages physical processes, its protection is vital for safety, reliability, and uninterrupted production.

As cyberattacks become increasingly sophisticated, product security is now crucial to ensuring OT security. A breach can halt operations, damage equipment, cause major financial and safety risks, and bring about potential loss of data. This makes tailored strategies essential for legacy systems, real-time demands, and the convergence of IT and OT networks.

Key Regulations and Standards Shaping OT Security Include:

  • Cyber Resilience Act (CRA): Sets higher EU-wide security requirements for products with digital elements, especially connected devices.
  • EU Machinery Regulation (EU) 2023/1230, applying from January 20, 2027, requires products to be protected against corruption and manipulation.
  • EU NIS2 Directive (EU) 2022/2555, applying from Oct 18, 2024, sets higher cybersecurity requirements for essential and important entities.
  • NIST SP 800-82: U.S. guide with best practices for OT architectures, threat mitigation, and response.
  • A Software Bill of Materials (SBOM) listing all libraries and dependencies in a software product to improve transparency and security.
  • IEC 62443: International standard for industrial control system security, from design to monitoring.
  • ISA/IEC 61511: Addresses safety instrumented systems where safety and cybersecurity intersect.

What Are Industrial Control Systems (ICS) and Why Are They Critical for Cybersecurity?

Industrial Control Systems (ICS) are hardware and software solutions that monitor, control, and automate processes across industries such as manufacturing, energy, water treatment, and transportation. Key components include SCADA systems for remote oversight, Distributed Control Systems (DCS) for centralized plant control, PLCs for specific factory tasks, and HMIs that let operators visualize and manage processes. Beyond ensuring safe and efficient operations, ICS are critical for defending against cyberattacks that can disrupt essential infrastructure. The Cyber Resilience Act (CRA) highlights this urgency, and Festo will ensure product security and support customers with compliant and reliable automation solutions.
