Networked devices increase cyber risks for building systems

Companies face an increasing but under-recognised threat from cyberattacks on building systems, and facilities managers need to act now with IT professionals to address the issue, independent research and advisory firm Verdantix is warning.

It highlights how a sharp rise in the number of connected devices across building systems mean that the operational technology (OT) used to run facilities creates a growing risk of cyberattack. Connected OT networks are converging with their IT counterparts, blurring traditional lines of responsibility for cybersecurity, just as ageing building systems require replacement and the number of attacks rises.

Without sufficient security controls, Verdantix warns that these systems are introducing significant new risks and more entry points for cybercriminals to exploit. The past five years have seen a massive explosion of Internet of Things (IoT) sensors and smart devices deployed, with firms frequently selecting these smart devices based on cost and functionality, resulting in facilities having many devices with poor built-in cybersecurity controls.

Verdantix’s ‘Best Practices: Enhancing Your Smart Building Cyber Security Programme’ found that firms are not aware of the full extent of their risk exposure from their OT, as they often do not keep registers of connected devices, or the level of cybersecurity protection provided.

Compiled after interviews with experts from the cybersecurity, IT and building technology sectors, the report shows how companies can adapt. Its publication comes as more connected devices via the IoT transform the landscape, but just 32% of firms evaluate IoT security risks as part of the onboarding process for third parties, and just 54% run penetration tests on their IoT devices.

Rodolphe D’Arjuzon, global head of research at Verdantix, said: “The first step for rebooting a smart building cybersecurity strategy is defining clear responsibilities and embedding cyber management into facilities operations across procurement, technology management and staff training.

“Facilities managers should not develop a siloed cyber programme on their own, but rather partner with their IT and security peers to integrate cybersecurity into different building management processes.”
