- GCHQ’s National Cyber Security Centre shares guide to help owners and operators of operational technology (OT) demand improved security in products
- Common weaknesses in OT components present opportunities for threat actors, who can replicate attacks across multiple victims, international cyber experts warn
- Operators of critical services are strongly advised to integrate security into procurement processes now to limit cyber risks
CRITICAL infrastructure organisations are being helped to secure their operational technology (OT) systems from growing cyber threats with new guidance agreed by cyber experts internationally.
The National Cyber Security Centre (NCSC) – a part of GCHQ – alongside agencies from the Five Eyes intelligence and security alliance and European partners have issued new advice today (Monday) which sets out key security considerations for organisations when purchasing OT products.
The guide aims to help OT owners and operators choose products and manufacturers that follow secure-by-design principles, so that their systems have a cyber resilient foundation from the point of purchase, minimising the risks posed by a successful cyber attack.
Operational technology systems are used widely in critical sectors globally but many components are not developed with security as a priority, presenting weaknesses which are being successfully exploited by cyber attackers.
Threat actors often target specific OT products, rather than specific organisations, because they can easily replicate attacks across multiple victims and sectors.
Organisations that own and operate OT systems are strongly encouraged to integrate the 12 security considerations outlined in the guide into their procurement processes to help defend against threats and to send a clear signal to manufacturers about the level of security they expect from products.
Jonathon Ellison, NCSC Director of National Resilience and Future Technology, said:
“As cyber attackers increasingly target operational technology around the world, it has never been more vital for critical infrastructure operators to ensure security is baked into the systems they use.
“This new guide gives organisations practical advice on how to prioritise OT products that are secure by design when making purchasing decisions, helping to mitigate the very real cyber threats they face.
“I strongly advise UK operators of OT systems to follow this guidance to help set a strong foundation for their cyber resilience and to send a signal to manufacturers that security is more than just an extra feature for products but a requirement in demand.”
Vendors and manufacturers have a key role to play in fixing foundational insecurities and taking responsibility for cyber security outcomes.
The 12 security considerations that organisations should consider when buying an OT product include: whether the product allows for security and safety logging, has strong authentication controls, protects data, is configured in a secure way by default, and is supported by established vulnerability management processes by the manufacturer.
The NCSC has previously outlined the importance of implementing secure-by-design principles within technology products at source so as to improve overall resilience and develop a safer cyberspace.
This work aligns with the objectives of the government’s forthcoming Cyber Security and Resilience Bill.
