What is a primary component of an effective eavesdropping countermeasure?

An effective eavesdropping countermeasure must incorporate both physical and electronic searches to thoroughly protect sensitive information. Physical searches involve scrutinizing a space for hidden microphones, cameras, or other unauthorized recording devices. This can include checking furniture, walls, and electronic equipment to detect any tampering or clandestine installations.

On the other hand, electronic searches utilize specialized equipment, such as spectrum analyzers or RF detectors, to identify active transmissions and signal sources that could be used for eavesdropping. By employing both methods together, security professionals can ensure a more comprehensive approach to countering potential eavesdropping threats.

Therefore, integrating both physical and electronic search techniques creates a robust defense against eavesdropping, making the combined approach the most effective countermeasure.
