What is OT Security and Why It Matters for Your Business
Operational Technology (OT) Security encompasses all practices and specialised technologies aimed at protecting the systems that manage and control industrial operations and critical infrastructures. In an increasingly digital and interconnected world, the convergence of IT and OT exposes organisations to new and complex cyber threats.
Unlike traditional cybersecurity, which focuses on data protection, OT security aims to ensure:
-
Safety: Prevent harm to people and the environment
-
Reliability: Maintain continuous operation of industrial processes
-
Productivity: Keep efficiency and production running without interruptions
OT includes the hardware and software that directly monitor and control physical devices, processes, and business events, including Industrial Control Systems (ICS) and SCADA systems.
Challenges of OT Security in Today’s Environment
Organisations face specific challenges in protecting their operational infrastructures:
-
Legacy systems: Many industrial environments rely on outdated technologies not designed for external network connectivity and lacking modern security measures.
-
Increased connectivity: Digitalisation and Industry 4.0 expand the attack surface, making OT systems vulnerable to threats that were once confined to IT networks.
-
IT/OT convergence complexity: Securely integrating IT and OT networks requires specialised expertise to prevent the creation of new vulnerabilities.
