GC security zones and dongle effectiveness: D97-1/2-2017E-PDF

"Mobile devices are important business tools that help government employees communicate and perform their duties in an effective and timely manner. Mobile devices use a microphone for voice communication, recording and voice commands. When the microphone is on, the information being discussed could be at risk. Threat actors can install malicious software (malware) which enables them to turn on the microphone remotely. Once the microphone is on, a threat actor could capture conversations from up to 20 meters away and transmit the information obtained to their counterparts without your knowledge. To counter this threat, a headset simulator plug (HSP), also known as a dongle, was designed to imitate a headset. In older versions of mobile devices, inserting the dongle into the headset plug physically disconnected the internal speaker and microphone"-- P. [1].
