About protecting an audio stream coming from sound recording devices

Available only in Kaspersky Standard, Kaspersky Plus, and Kaspersky Premium.

Intruders may attempt to receive the audio stream from sound recording devices by means of special software. Sound recording devices are microphones that are connected to or built into the computer and capable of transmitting an audio stream through the sound card interface (input signal). The Kaspersky application monitors which applications receive an audio stream from sound recording devices and protects the audio stream from unauthorized intercepts.

By default applications from Untrusted and High Restricted trust groups are not allowed to receive the audio signal coming from sound recording devices connected to the computer. You can manually allow applications to receive the audio stream from sound recording devices.

If an application from the Low Restricted trust group is requesting access to a sound recording device, Kaspersky displays a notification and prompts you to choose whether or not to allow this application to receive the audio stream from a sound recording device. If the Kaspersky application is unable to display this notification (for example, when the graphical interface of the Kaspersky application has not yet loaded), the application from the Low Restricted trust group is allowed to receive the audio stream from a sound recording device.

All applications in the Trusted group are allowed to receive an audio stream from sound recording devices by default.

Audio stream protection has the following special features:

• The Intrusion Prevention component has to be enabled for this functionality to work.
• After the settings of application access to sound recording devices have been changed (for example, the application has been prohibited from receiving the audio stream in the Intrusion Prevention settings window), this application has to be restarted to stop it from receiving the audio stream.
• Control of access to the audio stream from sound recording devices does not depend on an application's webcam access settings.
• The Kaspersky application protects access to built-in microphones and external microphones only. Other audio streaming devices are not supported.
• The Kaspersky application allows an application to receive an audio stream and does not show any notifications if the application began to receive the audio stream before the Kaspersky application was started, or if you placed the application into the Untrusted or High Restricted group after the application began to receive the audio stream.

The Kaspersky application does not guarantee protection of the audio stream from such devices as DSLR cameras, camcorders, and action cameras.
