NTT Docomo Business began preparing to develop an IoT security system with Tess Engineering to combat growing cyberattacks on devices by addressing threats at the network level.

The pair intend to develop ways to boost the security of communications infrastructure used for remote monitoring at solar power generation plants using an existing IoT-oriented Docomo network-as-a-service (NaaS) platform.

Docomo stated the IoT devices used to remotely monitor solar facilities typically lack the performance to implement effective security measures. There are also specific difficulties associated with the operating environment.

It explained Tess Engineering is a specialist in designing and operating solar power facilities and had already reported problems involving attacks on the communication systems used to transmit operational data to remote monitoring units.

The existing threat detection and blocking functions in Docomo’s NaaS platform are expected to help tackle the threats by providing notifications and blocking capabilities.

Tess Engineering is piloting the system at some of its solar sites and the companies plan to explore further measures to provide remote monitoring systems protections in a one-stop shop model.
