Smart Home Security: Protecting IoT Devices
Each smart device in your home is a potential entry point for hackers. Ring cameras have been hijacked to spy on families. Smart TVs have been compromised for cryptocurrency mining. This guide shows you how to secure your connected home.
The Reality of IoT Threats
- • Smart devices average 10 attack attempts per day
- • 75% of IoT infections target routers
- • Most devices ship with security disabled by default
The 5 Rules of Smart Home Security
1Change Default Passwords on Everything
Every smart device has an admin interface with default credentials. Attackers know them all. Change passwords on cameras, routers, smart hubs, and any device with an app.
2Enable Two-Factor Authentication
Enable 2FA on your Ring, Nest, Wyze, and other smart home accounts. This prevents hackers from accessing your cameras even if they get your password.
3Put IoT Devices on a Separate Network
Use your router's guest network or create a dedicated IoT network. This isolates smart devices from your computers and phones. If a device gets compromised, it can't access your personal data.
4Keep Firmware Updated
Enable automatic updates on all devices. Check monthly for devices that don't auto-update. Consider replacing devices that no longer receive security updates.
5Think Before You Buy
Before adding a device: Does it need internet access? Choose reputable brands with security track records. Check if they provide ongoing security updates.
Device-Specific Security
Security Cameras (Ring, Nest, Wyze)
- • Enable 2FA on your account
- • Use strong, unique password
- • Review shared user access regularly
- • Consider: Do you need interior cameras?
Voice Assistants (Alexa, Google Home)
- • Review and delete voice recordings periodically
- • Disable voice purchasing or add PIN
- • Mute when having sensitive conversations
- • Review connected skills/apps
Smart TVs
- • Disable ACR (Automatic Content Recognition) for privacy
- • Update firmware regularly
- • Don't enter sensitive data via TV apps
- • Consider: Cover built-in camera if you don't use it
Advanced: Network Segmentation
For maximum security, create separate network segments (VLANs) for different device categories. This requires a more advanced router or firewall.
Example Network Setup:
- • Main Network: Computers, phones, tablets
- • IoT Network: Smart TVs, thermostats, lights
- • Security Network: Cameras, locks, alarm
- • Guest Network: Visitors' devices
