Method and device for identifying risks of cyberattacks

Résumé

The present description concerns a method of identification of risks of cyberattacks on a programmable logic controller, the method comprising: the generation of a digital representation of a minimized finite-state transducer based on a specification of a controller logic of the programmable logic controller, the minimized finite-state transducer comprising a set of source states, a set of destination states, and a set of transitions from a source state to a destination state based on an input data value; the generation of a second computer file, based on a first computer file identifying a subset of sensitive states, the second file comprising a list of critical transitions associated with the sensitive states, and for each transition, a list of the input data; and the generation of a fourth computer file indicating input data to be protected which are both associated with critical transitions and with a corruption risk.
