CONTENTS INTRODUCTION CHALLENGES WITH SMART SPEAKING DEVICES TIPS TO SECURE COMMAND OR MESSAGE SEND TWO-FACTOR AUTHENTICATION WAYS TO SECURE YOUR GOOGLE HOME DEVICES CONCLUSION REFERENCES
Challenges with Google Home and Alexa Smart speakers are always listening (to catch the wake up word ) Unwanted triggering of commands (through TV or radios) Data stored in the cloud ( Vulnerable to unauthorized access) Adversarial attacks
(malicious actor sending false commands)
**Voice assistants can be commanded from outside your
home, even by others. Attackers can even use ultrasound
frequencies to avoid human detection
Tips to secure ‘command’ or ‘message send’
For Google Home you can disable “personal results” from showing up.
Erase sensitive recordings from time to time
Change the wake word.
If you are not using the voice assistant, mute it (according to your
convenience)
Protect the service account linked to the device with a strong password and
2FA where possible.
Use a WPA2 encrypted Wi-Fi network and not an open hotspot at home.
Create a guest Wi-Fi network for guests and unsecure IoT devices.
Lock the voice assistant down to your personal voice pattern, when
available.
Don’t use the voice assistant to remember private information such as
passwords or credit card numbers.
Pay attention to notification emails, especially ones about new orders for
goods or services.
Consider enabling a beep sound at the beginning and end of command
recognition.
Do not turn off automatic update functions on the device.
TWO WAY AUTHENTICATION Fingerprint recognition
(Fingerprint Scanner on device)
Facial recognition (Authorized face can give command ) Security tokens
( one-time passwords that a user may
receive via SMS )
Voice recognition
(Only registered voice can give commands)
Ways to Secure Your Google Home Device Enable voice match Limit external devices Use two-factor authentication
Mute Google Home
Discard old voice recordings
