Step by step
Enforce Multi-Factor Authentication
Open your camera manufacturer’s application and navigate to Account Settings. Enable Multi-Factor Authentication (MFA) using a dedicated authenticator app rather than SMS. This ensures that even if your password is compromised, the live feed remains inaccessible to unauthorized users.
Note: Use a hardware-backed authenticator like YubiKey if the service supports it.Update Firmware and Enable Auto-Updates
Access the Device Settings for every connected camera to confirm the firmware is on the latest version. Toggle the Auto-Update switch to the On position to ensure critical security patches are installed immediately upon release. Never delay a security update for hardware that monitors your physical space.
Create a Dedicated Guest Network
Log into your router’s web interface and create a secondary Wi-Fi network specifically for IoT devices. Assign all smart cameras to this Guest Network to isolate them from your primary devices, such as laptops and NAS drives. This prevents a compromised camera from serving as an entry point to your main computer network.
Note: Ensure 'Guest Isolation' is enabled in your router settings to prevent inter-device communication.Disable Universal Plug and Play
In your router settings, locate the UPnP (Universal Plug and Play) configuration. Disable this protocol entirely to prevent cameras from automatically opening ports on your firewall. Manual port forwarding is safer and more secure, but should be avoided in favor of manufacturer-provided cloud relay services.
Note: If you are not using UPnP for gaming or specific services, keep it permanently disabled.Remove Unused Linked Accounts
Review the 'Connected Apps' or 'Third-Party Access' list within your camera account settings. Revoke access for any platforms, voice assistants, or apps that you no longer actively use to stream your camera footage. Minimizing the number of integration points reduces your total attack surface.
