Some embodiments described herein include an apparatus having a processor communicatively coupled to a memory. The processor is configured to monitor, at a characteristic controller, a first characteristic of an electronic device. The processor is then configured to receive side-channel signature analysis of the electronic device from a signature analyzer. The processor is configured to determine if the first characteristic of the electronic device has changed or will change in a predefined period of time based on the side-channel signature analysis. The processor is then configured to adjust a second characteristic of the electronic device and/or filtering characteristics such that the side-channel signature analysis reflects predefined side-channel behavior.
