NSA's TEMPEST specificаtiоn аddresses side chаnnels that can be created when an attacker is clоse tо a computer processing sensitive data and is able to record signals emanating from the system (e.g., emitted electromagnetic signals can be captured with an antenna). One kind of signal is the sound that is made by the fan to cool the chips when it runs various types of code.
