Vulnerability discussion

Microphones can capture audio of sensitive information. There is also a potential for remote access, and microphones must be turned off unless approved by local policy.

Check content

Verify microphones are turned off unless approved by the organization. View status in device manager. If built-in microphones are not approved by local policy or disabled, this is a finding. If the system does not have built-in microphones, this is not applicable.

Fix text

Disable microphones in device manager if not organizationally approved.
