Safety of IoT systems

Connected objects, known as IoT, are everywhere – even in critical applications – and they need to be controlled.

Connected objects have taken over our day-to-day life, and are also widely used in many industrial applications. Initially reluctant sectors such as the rail and nuclear industries are now turning to these new technologies more and more. We know that they enable the introduction of new features, help consolidate information to ensure effective predictive maintenance, or help improve the safety of a system.

The proliferation of these objects means that special care needs to be taken when developing critical systems that use these technologies. At the same time, they have ushered in significant changes in the risks of attacks and vulnerabilities that can affect the safety and security of people.

For safety applications, IoT system designers need to focus on incorporating specific development requirements, in order to integrate the constraints of the standards applicable to each sector as soon as possible (from the concept or specification phases).

SERMA Safety & Security, through its wide-ranging expertise, assists manufacturers in the control of their design with a combined Safety/Security approach. Potential vulnerabilities can allow attackers to read unencrypted data stored on the memory of electronic boards, retrieve intellectual property-protected information on microprocessors/microcontrollers, capture keys that are sent between components, or even use that information to degrade the dependability of a system.

Safe IoT systems in any type of application

 Our added value is to provide support that is tailored to the risk level, the application and the constraints of our customers.
