Cybersecurity for Construction Applications

Data is becoming as fundamental to the construction industry as bricks or mortar. If companies have access to real-time information on their assets they can monitor, analyze, and optimize their performance. An increasing number of Internet of Things (IoT) devices are being deployed to provide that intelligence, but they can also expose firms to risks as not all these connected products have been designed with security in mind. With a growing risk of cyberattack, connected products must have security built-in.

To help industries benefit from IoT innovation without becoming an easy target for hackers, global technology, supply chain, and manufacturing solutions company, Flex, developed its iENBL low power, rapid development platform, using the ST Microelectronics STM32L4 (Arm Cortex-M4). Start-ups are using the platform to reduce the time and cost involved in developing and testing IoT devices that solve the construction sector’s challenges. MachineMax, for example, is a UK-based company that wanted to help customers track and manage their heavy machinery. It had realized that, in some cases, its customers’ off-highway vehicles were idling up to 50% of the time, at a cost of tens of thousands of dollars.


Flex helped MachineMax speed up the development of an IoT tracker that can improve the efficiency of a fleet, reduce maintenance and environmental costs, and increase productivity on site. Importantly for MachineMax and its customers, who need to be able to trust the device and the data it generates, Flex had built security into its platform from the outset.

Deploying security features into connected devices is tricky, so Flex used the PSA Certified security framework to help assure customers that their product is protected against the most common cyberattacks. Flex took proactive steps to achieve PSA Certified Level 1 certification, on their iENBL platform, which means its security is in line with industry best practices and meets major cybersecurity standards, requirements, and regulations.
