Systems and methods for side-channel monitoring of a processor connected to a communication network

A system for monitoring at least one device processor connected to a communication network, the system comprising:

• at least one detector operable to generate a program trace signal from at least one side-channel of the at least one device processor;
• a communication component to provide access to the communication network;
• and
• at least one monitoring processor in communication with the communication component and the at least one detector, the at least one monitoring processor being operable to:
• transmit at least one communication of at least one test message to the at least one device processor via the communication network;
• for each communication, collect a program trace signal generated by the at least one device processor in response to the communication;
• compare the at least one program trace signal to an expected response of the at least one device processor for the at least one test message to determine whether the at least one program trace signal corresponds to the expected response;
• and
• in response to determining that the at least one program trace signal does not correspond to the expected response, generate an anomaly notification.
