In today’s interconnected world, the risk of cybersecurity threats to operational technology (OT) systems is ever-present and growing. With technology playing a crucial role in industrial operations and business continuity, organizations face a constant barrage of cyberattacks targeting the networks and systems that control production processes. Recent statistics show that a staggering 61% of cyberattacks in 2021 were directed specifically at OT networks (Fortinet, 2022).
OT cybersecurity focuses on implementing technologies and processes to monitor, control, and protect enterprise OT networks from cyber threats. Given the diverse range of devices and systems interconnected in OT networks, including those connected to the Industrial Internet of Things (IIoT), it’s essential to deploy robust security measures to prevent unauthorized access and minimize the risk of disruptions to critical production infrastructure caused by cyberattacks.
Key Considerations for OT Cybersecurity
-
1. Non-negotiable Security: The potential impact of a cyberattack on an OT network, both in terms of financial losses and reputational damage, underscores the critical importance of protecting organizational processes.
-
2. Security must be prioritized to ensure the continuity of industrial operations.
Visibility, Control, and Continuous Monitoring: Comprehensive cybersecurity requires visibility into all components of the OT architecture and infrastructure. By understanding the interconnected nature of OT systems, organizations can implement proactive security measures and controls to mitigate risks effectively. Continuous monitoring is essential for identifying and addressing emerging threats in real-time. -
3. Business Impact and Importance: Cyberattacks on OT systems pose significant risks to business continuity, leading to financial losses, data breaches, and operational disruptions. These attacks can also damage the reputation and trustworthiness of the organization, underscoring the critical need for robust cybersecurity measures.
In summary, OT cybersecurity is essential for safeguarding industrial operations against the growing threat of cyberattacks. By prioritizing security, maintaining visibility and control over OT networks, and understanding the business impact of cyber threats, organizations can mitigate risks and ensure the uninterrupted operation of critical processes.
