METHOD FOR MONITORING AN ELECTRONIC SYSTEM USING LOW-LEVEL PERFORMANCE COUNTERS AND COMPRISING AT LEAST ONE SET OF UNCONTROLLED SOFTWARE APPLICATIONS THAT ARE EXECUTED ON A PROCESSOR, AND A MONITORING DEVICE

Method that monitors the operation of a system executing, on a processor, applications following user actions and that computes HPC values, comprising the following steps: - predicting, using an algorithmic model, next HPC values depending on current HPC values and on the actions; said model being the result of a machine learning process based on input training data comprising successive HPC values and actions; - verifying the conformity of operation of the system using an electronic monitoring module (17) depending on one or more characteristics of a computed first deviation between computed HPC values and HPC values predicted by the first algorithmic model; and triggering an alarm using said electronic monitoring module on detection of a non-conformity.
