The UK’s Cyber Security Centre Says: Your ICS/OT Security is Only as Strong as Your Team
On March 13, 2025, the UK’s National Cyber Security Centre (NCSC) published a blog post emphasizing a critical element often overlooked in the rush to secure Industrial Control Systems (ICS) and Operational Technology (OT): the team responsible for protecting them. Titled “The strength of the ICS COI is the team,” the post highlights the importance of a well-trained, collaborative, and empowered team as the cornerstone of robust ICS/OT security.
Let’s break down what this means in plain English:
What are ICS and OT?
Think of ICS and OT as the brains and muscles behind critical infrastructure and manufacturing. They control things like:
- Power plants: Managing electricity generation and distribution.
- Water treatment plants: Purifying and delivering clean water.
- Manufacturing facilities: Operating assembly lines and automated processes.
- Transportation systems: Controlling traffic lights, train networks, and airport operations.
These systems are traditionally separated from standard IT networks for security and reliability reasons. However, with increasing digitalization, they are becoming more connected, making them vulnerable to cyberattacks.
Why is ICS/OT Security Important?
Attacks on ICS/OT systems can have devastating consequences, including:
- Disruptions to essential services: Imagine a city without power or clean water.
- Damage to equipment: Hackers could potentially cause physical damage to machinery, leading to costly repairs and downtime.
- Environmental disasters: Attacks on chemical plants or oil pipelines could release harmful substances into the environment.
- Loss of life: In extreme cases, manipulated ICS/OT systems could directly endanger human lives.
The Key Takeaway: It’s All About the Team!
The NCSC blog post argues that having the latest security tools and technologies isn’t enough. A successful ICS/OT security program relies heavily on the people behind it – the security team. Here’s why:
- Expertise and Training are Crucial: ICS/OT environments are unique and require specialized knowledge. IT security professionals familiar with traditional networks may not fully understand the complexities and vulnerabilities of these systems. Teams need specific training in ICS/OT protocols, architectures, and security best practices.
- Collaboration is Key: ICS/OT security requires close collaboration between IT security teams, operations personnel, and engineers. Each group brings a different perspective and skillset to the table. Effective communication and shared understanding are essential for identifying risks and implementing appropriate security measures.
- Empowered Teams Make Faster Decisions: In a crisis, time is of the essence. Teams need to be empowered to make quick decisions and take decisive action without unnecessary bureaucracy. This requires clear roles and responsibilities, as well as a culture of trust and accountability.
- Understanding the Business is Vital: The team must understand the specific operational processes and priorities of the organization. Security measures should be tailored to minimize disruption and maximize uptime while still mitigating risks effectively. They need to be able to translate technical risks into business impacts that leadership can understand.
- Continuous Learning and Improvement: The threat landscape is constantly evolving. ICS/OT security teams need to stay up-to-date on the latest threats and vulnerabilities, as well as emerging security technologies. Regular training, workshops, and participation in industry forums are essential for continuous learning and improvement.
What Does This Mean for Organizations?
The NCSC’s message is a call to action for organizations that rely on ICS/OT systems. Here’s what they need to do:
- Invest in Training: Provide specialized training for security teams on ICS/OT security principles and best practices.
- Foster Collaboration: Create a culture of collaboration and communication between IT security, operations, and engineering teams.
- Empower Teams: Give teams the authority and resources they need to make informed decisions and take timely action.
- Develop a Comprehensive Security Program: Implement a robust security program that addresses all aspects of ICS/OT security, including risk assessment, vulnerability management, incident response, and security awareness training.
- Regularly Review and Update Policies: Ensure that security policies and procedures are regularly reviewed and updated to reflect the changing threat landscape and evolving business needs.
In Conclusion
The NCSC’s blog post is a valuable reminder that technology alone cannot guarantee ICS/OT security. A well-trained, collaborative, and empowered team is the foundation of a strong security posture. By investing in their people, organizations can significantly reduce their risk of cyberattacks and protect their critical infrastructure. It is also a reminder that, even with advanced automation, a skilled and informed team will still be the critical component for any system.
