It started with a Ring doorbell, like it does for so many families. Then came the smart thermostat, followed by the outdoor cameras when we realized the raccoons were having nightly raves on our deck. Now? I can control half the house from my phone. But with all this convenience comes a new set of worries: connected home security tips.

The peace of mind from knowing my kids got home from school safe is great. The lower energy bill thanks to automated temperature settings is even better. But I’ve learned the hard way that a smart home isn’t automatically a secure home. You have to be proactive. It’s easy to overlook crucial steps. I’ve made plenty of mistakes along the way. Hopefully, I can help you avoid them.

> * Don’t rely solely on default settings—customize everything.

> Two-factor authentication is your best friend. Use it on everything*.

> * Keep your software updated. Seriously, set a reminder.

> * Secure your router. It’s the gateway to your whole smart home.

> * Educate everyone in your household about security best practices. Even the kids.

Neglecting Router Security: The Front Door to Hackers

Your router is the central hub of your entire smart home. If it’s compromised, everything else is vulnerable. The default username and password? Hackers know them. I’m always shocked how many people leave these as-is. Change them immediately.

Here’s what to do:

• Strong Password: Use a complex password (at least 12 characters, mixed case, numbers, symbols).
• Update Firmware: Keep your router’s firmware updated. Most routers have an automatic update feature—enable it.
• Disable Remote Access: Unless you absolutely need it, disable remote access to your router’s settings.
• Enable WPA3: Use WPA3 encryption for your Wi-Fi network. It’s the most secure option currently available.

I ran a speed test on my internet recently and discovered my ancient router was throttling my bandwidth by almost 40%. Upgrading it was a double win—faster internet and better security.

Skipping Two-Factor Authentication (2FA)

If I could only give one piece of connected home security tips, this would be it. Enabling two-factor authentication (2FA) adds an extra layer of security to your accounts. It requires a second verification method (like a code sent to your phone) in addition to your password.

Honestly, I resisted 2FA for a long time because I thought it was a hassle. But after a friend’s email account was hacked, I realized the extra 30 seconds was worth it. Now, I have 2FA enabled on every account that offers it—email, social media, banking, and (of course) all my smart home devices.

Forgetting to Update Device Firmware

Smart home devices regularly receive firmware updates that patch security vulnerabilities and improve performance. Neglecting these updates is like leaving your doors unlocked.

The one thing that frustrates me about firmware updates is that they often seem to come at the most inconvenient times. But I’ve learned to schedule them for overnight, so they don’t interrupt my family’s routines. Many devices can update automatically—make sure that feature is turned on.

Using Weak or Reused Passwords

This is a basic security mistake that extends beyond smart homes, but it’s especially crucial here. Using weak passwords (like “password123” or your pet’s name) or reusing the same password across multiple accounts makes it easy for hackers to gain access to your entire smart home ecosystem.

Use a password manager like LastPass or 1Password to generate and store strong, unique passwords for all your accounts. They even have built-in security alerts to warn you about compromised sites.

Ignoring Privacy Settings on Smart Devices

Smart devices often collect a lot of data about your usage habits. While some of this data is used to improve device performance, it can also be shared with third parties for marketing purposes.

Take some time to review the privacy settings on each of your smart devices and adjust them to your liking. Disable features you don’t need, and opt-out of data sharing whenever possible. Read the privacy policies carefully. It’s tedious, I know, but it’s worth it.

Overlooking the Security of Connected Cameras

Connected cameras are great for keeping an eye on your home, but they can also be a major security risk if not properly secured. Make sure to change the default password, enable two-factor authentication, and keep the firmware updated.

I’ve also seen stories about hackers gaining access to cameras and using them to spy on families. To prevent this, cover your camera lenses when you’re not using them. A simple piece of tape will do the trick. I also make sure my kids know not to mess with the cameras. Child-safety is paramount.

Failing to Segment Your Network

If you have a lot of smart home devices, consider segmenting your network. This involves creating a separate Wi-Fi network specifically for your smart devices. This way, if one of your smart devices is compromised, the hacker won’t be able to access your computers, phones, and other sensitive devices on your main network.

Many modern routers offer a “guest network” feature that can be used for this purpose. This is a relatively easy way to create a separate network for your smart devices without having to buy a second router.

Not Educating Your Family About Smart Home Security

Smart home security isn’t just about technology—it’s also about people. Make sure everyone in your household understands the importance of security best practices.

Teach your kids not to click on suspicious links or open attachments from unknown senders. Explain to them why it’s important to keep their passwords secret and to be careful about what they share online. This is especially important for teens who are active on social media.

Relying Solely on Default Security Settings

Smart home devices often come with default security settings that are not very secure. These settings are designed to be easy to use, but they often sacrifice security for convenience. For example, many smart devices use default passwords that are easy to guess.

Take the time to customize the security settings on each of your smart devices. Change the default password, enable two-factor authentication, and adjust the privacy settings to your liking. Don’t just assume that the default settings are good enough.

Ignoring Physical Security Measures

Smart home security isn’t just about protecting your devices from hackers. It’s also about protecting your home from physical intrusion. Don’t forget to take basic physical security measures, such as locking your doors and windows, installing a security system, and trimming bushes around your property.

A smart lock is a great addition, but it’s not a replacement for a sturdy deadbolt. Think of connected home security tips as a layered approach. The more layers you have, the more secure your home will be.

What I’d Tell a Friend

Look, building a smart home is cool. It makes life easier. I can’t deny that. But don’t get so caught up in the convenience that you forget about security. It’s not a one-time setup. It’s an ongoing process.

Take the time to understand the risks, implement the necessary security measures, and stay vigilant. Your family’s safety and privacy are worth it. And if you’re feeling overwhelmed, start small. Focus on securing your router and your most critical devices first. You can always add more security layers later.
