Smart home devices — TVs, thermostats, doorbells, CCTV cameras, smart speakers — are increasingly targeted by cybercriminals. Unlike PCs, most IoT devices can’t run antivirus software. The best protection is router-level security and network segmentation.

Key Points
- Create a separate guest Wi-Fi network for all smart devices (most modern routers support this)
- This isolates smart devices from your main network where your PCs and phones operate
- Change default passwords on all smart devices immediately (many use ‘admin/password’ by default)
- Keep smart device firmware updated — check manufacturer apps for updates
- Disable remote access on smart devices unless you actively use it
- CCTV cameras with weak passwords are a common entry point for criminals
- McAfee VPN protects your phone/PC from threats on the main network even if smart devices are compromised
- McAfee Secure Home Platform (router firmware) provides IoT scanning for compatible routers
