Here, we are at the level of networks on the ground in the workshop. We find connected objects (sensors on equipment to enable them to dialogue with each other and dialogue with the product). It is necessary to have data transmission supports between these devices and here, cybersecurity is at the heart of the challenges of protection against acts of malice, in these new layers which appear. It is absolutely essential to protect oneself from malicious acts which, from a simple smart phone, could directly attack the management parameters of one’s production and affect the quality or the security of the products. These are technologies which allow products to be connected to each other, to machines and even machines which are connected to each other, all thanks to secure infrastructures.
We find for example autonomous, communicating sensors (RFID), acquisition cards to collect physical data such as noise, temperature, spindle power, torque…The industrial networks make it possible to transport information collected « in the field » so as to make it available at higher levels. This feeds the big data.
