1. A method comprising:
enabling a plurality of peripherals for a configuration of an electronic device, where each enabled peripheral is enabled from a group of peripherals corresponding to a peripheral type, where each group of peripherals is coupled to a host board;
monitoring, during an operation performed by the host board using at least one peripheral of the enabled plurality of peripherals, at least one signal that propagates between the host board and the at least one peripheral; and
generating a signal fingerprint for the operation performed by the host board using the at least one peripheral based on monitoring the at least one signal, the signal fingerprint representing at least one characteristic of the at least one signal corresponding to the operation.
