WHAT IS OT cyberSECURITY?

Operational Technology (OT) describes environments comprising Industrial Control Systems (ICS), including Industrial Automated Control Systems (IACS), Supervisory Control and Data Acquisition (SCADA), and Process Control Networks (PCN).

OT cybersecurity focuses on protecting these environments from cyber risks. Cyber threats to OT systems pose significant risks, as attacks can lead to calamitous and catastrophic outcomes affecting infrastructure and society.

Why is OT Cybersecurity Important for Your Organisation?

OT environments carry a higher inherent risk compared to IT systems due to:

  • Weak access control across physical and logical regions
  • High functionality-dependent design principles
  • Complex involvement of personnel across project stages

Cyberattacks on OT systems have resulted in:

  • Loss of public reputation
  • Equipment damage
  • Leakage of sensitive data and information

Frequently asked questions (FAQ)

  • What are affordable OT cybersecurity tools for small and medium enterprises?

    Affordable OT cybersecurity tools for small and medium enterprises focus on visibility, monitoring, and risk management. Common options include network monitoring tools, asset discovery solutions, vulnerability management tools, intrusion detection systems (IDS), and secure remote access solutions. These tools help organisations detect threats early while maintaining cost efficiency and scalability.

  • What are the key differences between IT and OT cybersecurity strategies?

    The key difference between IT and OT cybersecurity lies in their priorities. IT cybersecurity focuses on protecting data and systems, while OT cybersecurity focuses on ensuring the safety and continuous operation of physical processes. OT environments prioritise availability and reliability, whereas IT environments prioritise data confidentiality and integrity. 

  • How to implement OT cybersecurity in manufacturing plants?

    To implement OT cybersecurity in manufacturing plants, organisations should adopt a risk-based approach. This includes identifying and inventorying OT assets, conducting risk assessments, segmenting IT and OT networks, implementing continuous monitoring, enforcing access controls, and preparing incident response plans. These steps help ensure safe, reliable, and secure industrial operations.
