These days, nearly any device can connect to the web. Smartphones, lights, cameras, thermostats, speakers, watches, doorbells, and appliances can communicate and be controlled remotely. All this interconnectivity creates vulnerability to cyber attacks, putting devices and shared info at risk. So, are smart home devices safe? Let's get to the root of these security risks and how to reduce them.

What Are Smart Home Devices?

Smart home technology uses a network of internet-connected devices that can be controlled and monitored remotely. Smart tech can help improve home security, enhance entertainment, or simply make daily tasks like writing grocery lists or turning on lights more convenient.

Connecting devices together requires a hub, which could be a network router or a smartphone. Smart homes collect, store, and share usage data through the hub, which may help homeowners save energy or automatically tune their devices to their specific needs and preferences.

Smart Home Security Risks and Vulnerabilities

Despite the convenience, all the data sharing and internet connectivity of a smart home network can also create a personal data security risk. Each device adds new privacy concerns.

Smart home safety comes down to the configuration of these individual devices as well as the security of the network they're on. For example, if the data in your network isn't secure, hackers may track your usage patterns to see when you're away. Unprotected smart homes are also vulnerable to the following threats, among others.

Personal Data and Identity Theft

Smart home devices often store sensitive data. Hackers can access personal details, email passwords, social media accounts, and even banking or credit card information.

Device Hijacking

When a cyber attacker gains control of a smart device, they can put you and your home at risk. They may see inside your home through security cameras, control what you see on your display, break into smart locks, and access smart speakers to speak to you directly.

Other Attacks

There are many other ways for hackers to disrupt smart devices. By intercepting communication between two devices, they may be able to send false requests, create false alarms, or even install malware. They could even render a device completely useless, meaning you'll have to pay to have it replaced.

Don’t let security threats prevent you from taking advantage of modern smart technology. Instead, take measures to set up your smart home so that it’s secure. This should be done in two ways: First, by securing your network, then by securing your individual smart devices.

Securing Your Home Network

Start by isolating your smart home network from other networks in your home. The simplest way to do this is to set up a guest network for your smart devices and appliances separate from the main network you use for personal phones and computers. This will prevent your personal devices from becoming infected if a smart device gets hacked.

Securing Your Smart Devices

With your network secured, move on to securing all of your individual devices. Before you buy any device, do research to ensure the manufacturer provides regular updates. These updates are designed in part to protect against the latest security threats. If your device doesn't update automatically, be sure to update it as often as possible.

Be wary of voice-activated devices that are constantly listening, such as smart speakers. If you don't intend to use voice controls on a device, turn the microphone off. If your device responds to a specific voice command, make it one that's unique to your family rather than the default.

Create a unique, strong password for every device with a difficult-to-guess string of lowercase and uppercase letters, numbers, and characters. You can keep track of passwords using a password manager, so you don't have to keep anything written down.

Are Smart Home Devices Worth It?

Smart home devices present some security challenges. However, if you're careful and take steps to protect yourself and your home, they also offer a number of advantages.

  • Smart lighting can be turned on no matter where you are in the world to make it look like someone is home.

  • Smart locks remove the need to hide a spare key under the doormat and help you manage access for house sitters and cleaners.

  • Door and window sensors can tell you when you've left an entry point unlocked.

  • Wi-Fi security cameras let you monitor your front door and track deliveries.

  • Smart appliances self-adjust to operate more efficiently and save you money on utilities.

These are just some of the benefits that smart devices have to offer. Keep in mind that you'll need to secure every new device you buy. Additionally, even after you've followed the measures to secure your network and devices, you'll need to stay diligent and monitor your system regularly to keep your home truly safe.
