Abstract
Methods, apparatus, systems and articles of manufacture for detecting a side channel attack using hardware performance counters are disclosed. An example apparatus includes a hardware performance counter data organizer to collect a first value of a hardware performance counter at a first time and a second value of the hardware performance counter at a second time. A machine learning model processor is to apply a machine learning model to predict a third value corresponding to the second time. An error vector generator is to generate an error vector representing a difference between the second value and the third value. An error vector analyzer is to determine a probability of the error vector indicating an anomaly. An anomaly detection orchestrator is to, in response to the probability satisfying a threshold, cause the performance of a responsive action to mitigate the side channel anomaly.
