From Reactive to Proactive: Practical Steps to Secure Your IoT and Smart Devices
The unpatched or unsecured Internet of Things (IoT) devices, from security cameras to smart thermostats, can serve as entry points for hackers because they are literally unlocked doors that should be secured. Here are some practical steps you can take to secure these devices in your home and business.
1. Start with Your Network (the foundation)
Change default equipment (e.g., modem, computer, router) passwords — Criminals often know the factory-set passwords. Use a long, unique one.
Update equipment firmware — Just like computers, routers need updates for security holes.
Use WPA3 (or at least WPA2) Wi-Fi encryption — Never use “open” Wi-Fi.
Separate your networks — Put smart devices (like cameras, thermostats, TVs) on a guest or IoT network, separate from computers and phones where sensitive business or personal data is stored.
2. Lock Down Each Device
Change default usernames and passwords immediately when setting up.
Turn on automatic updates so devices get security patches.
Disable unused features (like remote access, voice assistants, or Bluetooth) if you don’t need them.
Use multi-factor authentication (MFA) for apps linked to your smart devices, especially cameras and door locks.
3. Secure User and Device Access & Monitoring
Review device permissions — Check which apps, people, or accounts have access. Remove old users.
Enable logging or alerts where available — Many smart cameras and hubs can alert you to new logins or settings changes.
Monitor for unusual behavior — Devices suddenly slowing, crashing, or running at odd hours can indicate compromise.
Train staff — Employees should know not to connect personal IoT devices (like smart speakers or wearables) to business networks.
4. Protect Your Data
Read privacy settings in the app — Limit data sharing to only what’s needed.
Encrypt stored data if the device allows it.
Back up configurations so you can restore settings if a device must be reset.
Use firewalls or intrusion prevention systems (IPS) if possible.
5. Secure Physical Equipment and Spaces
Place smart cameras and locks where they’re not easily accessible.
Unplug unused devices when traveling or during downtime.
Keep routers, hubs, and IoT controllers in a locked room or cabinet to prevent tampering.
Implement and manage physical user access controls within buildings and spaces
6. Manage Vendor & Equipment Lifecycle
Inventory all connected devices — Know what’s on your network.
Buy from reputable brands with a history of issuing security updates.
Check support timelines — Some devices only receive updates for a few years.
Plan for replacement — Outdated, unsupported devices should be retired.
Every smart device is a potential doorway into your home or business. Securing them is not about fancy tools — it’s about changing defaults, keeping software updated, segmenting networks, and monitoring activity. Treat IoT devices like you would physical doors: lock them, check them regularly, and replace weak ones. Depending on your industry, you may require insurance and compliance with regulatory standards. Consult with legal counsel with information privacy and security expertise.
