Abstract
An apparatus comprising: a processing unit configured to execute a plurality of threads; a profiling unit configured to: profile the operation of the processing unit over a time period to generate an activity profile indicating when each of the plurality of threads is executed by the processing unit over the time period; analyse the generated activity profile to determine whether a signature of the processing unit's thread execution for the time period matches a signature indicating a baseline of thread execution for the processing unit; output an alert signal if the signature of the processing unit's thread execution for the time period does not match the signature indicating a baseline of thread execution for the processing unit.
