UK’s NCSC Releases SCADA Security Guidance to the Cloud


The National Cyber Security Centre (NCSC) of the United Kingdom has recently published a comprehensive set of guidelines designed to assist organizations in securely transitioning their Supervisory Control and Data Acquisition (SCADA) systems to cloud environments.

This move comes as industries increasingly leverage the cloud’s capabilities to enhance operational technology (OT) infrastructure.

SCADA systems are pivotal in managing and controlling critical national infrastructure (CNI) and other cyber-physical systems.

They enable the monitoring and manipulation of physical processes across various industries, including utilities, transportation, and manufacturing.

The Benefits and Challenges of Cloud-Hosted SCADA

The guidance provided by the NCSC outlines the potential advantages of cloud-hosted SCADA, such as improved data processing, scalability, and resource optimization.

However, it also addresses the unique challenges associated with cloud adoption, particularly in cybersecurity.

Organizations considering migrating SCADA systems to the cloud are encouraged to conduct a thorough risk-based assessment.

This includes understanding the cybersecurity implications and ensuring that the benefits outweigh the potential risks.

Cybersecurity at the Forefront

With infrastructure’s increasing connectivity, the threat landscape for SCADA and CNI has evolved.

The NCSC’s Annual Review 2023 indicates a significant rise in the cyber threat level to the UK’s CNI over the past year.

Moreover, a joint advisory with the United States Cybersecurity and Infrastructure Security Agency (CISA) has highlighted specific threats from state-sponsored actors, such as China, targeting UK CNI.

The guidance emphasizes the importance of cybersecurity in decision-making processes for CNI and broader cyber-physical systems.

It is crucial for organizations to recognize the challenges associated with a cloud shift and to apply the NCSC’s cloud security guidance, which shares commonalities with IT security in cloud-hosted SCADA systems.

As per the recent tweet by DeepBlue Security & Intelligence, if operational technology organizations plan to shift their SCADA solutions to the cloud, they must give utmost importance to cyber security.

Moving Forward with Informed Decisions

The NCSC’s guidance is not prescriptive but aims to equip organizations with the knowledge to make informed, risk-based decisions regarding implementing cloud-hosted SCADA.

It is a call to action for organizations to weigh the benefits against the unique challenges and to prioritize cybersecurity in their strategic planning.

As cloud-hosted SCADA becomes an increasingly mature and adopted technology, the NCSC’s guidance is a critical resource for organizations navigating this transition.

By adhering to these guidelines, UK organizations can fortify their defenses against evolving cyber threats while harnessing the power of the cloud to drive innovation and efficiency in their OT operations.
