A hacked smart home poses a severe threat to your safety and privacy. Intruders can unlock your doors, disable your security cameras, and even harm you remotely. Most importantly, they can steal sensitive data, such as passwords, bank information, and credit card details, leading to identity theft and financial loss.

Protecting your smart devices is essential to safeguarding your privacy and security. Some tips to keep in mind include:

  • Use strong, unique passwords for each device and change them regularly.
  • Keep your devices up-to-date with the latest software updates and security patches.
  • Disable any unnecessary features or services that could be used to gain access to your home network.
  • Consider using a virtual private network (VPN) to encrypt your internet traffic and protect your privacy.
  • Ensure your home Wi-Fi network is using WPA2 or WPA3 Encryption. Avoid WEP, as it is outdated and insecure.
  • Use all of the available built-in security features in all your smart devices and enable multi-factor authentication.

Securing Your Home Network

Securing your home network is of paramount importance. Modern routers offer multiple security features, such as WPA3 Encryption, which should be used over outdated and insecure protocols like WEP.

Using a unique password for your Wi-Fi network and regularly updating your router’s firmware are essential steps in securing your network.

Here are some tips that you can use to secure your network:

Choosing a Strong Password

Choosing strong passwords is one of the most important steps in securing your home Wi-Fi network. To prevent brute force attacks, choose a long and complex password. Include upper and lowercase letters, numbers, and special characters.

Also, avoid using common words and phrases – they’re easy to guess.

Finally, use a good password manager so you don’t have to remember your passwords or write them down, increasing your security risks.

Updating Your Router’s Firmware

Regularly updating your router’s firmware allows you to patch any known vulnerabilities and keep your router running smoothly. Router manufacturers often release firmware updates to fix security flaws, so it is important to keep your Wi-Fi router up-to-date.

You can usually check for updates through your router’s web interface.

Setting Up a Guest Network

Setting up a guest Wi-Fi network is a great way to provide your guests with internet access without allowing them access to your devices and data. This is particularly important if you have sensitive information on your devices that you do not want to share.

A guest network is also useful if you have children who have friends over, as it allows them to connect to the internet without accessing your personal network.

Using a Virtual Private Network (VPN)

Using a Virtual Private Network (VPN) is another way to secure your home network. A VPN encrypts your internet connection, keeping hackers from eavesdropping on your traffic.

Use a VPN when accessing sensitive information, such as bank accounts or credit card details. This is especially important if you are using public Wi-Fi, as these networks are often unsecured.

Strengthening Device Security


Here are some steps you can take to ensure the security of your devices:

Regularly Updating Device Software

Manufacturers often release software updates to address security vulnerabilities. These updates can help protect your device from potential threats. Be sure to update your devices as soon as updates are available. Keep in mind that many smart devices may not have automatic updates, so it is important to check for updates regularly.

In addition to updating your device software, it is also important to keep your router’s firmware up to date. The router is the gateway to your network, so keeping it secure is crucial.

Disabling Unnecessary Features

Many smart home devices come with unnecessary features that can leave your device and network vulnerable. If you don’t use them, you should disable remote access, voice control, and the camera.

If you’re not using these features, it is best to disable them. This will reduce the attack surface of your device and make it less vulnerable to potential threats.

Implementing Two-Factor Authentication

Two-Factor Authentication (2FA) adds an extra layer of security to your devices. It requires you to input a code sent to your phone or email before accessing your device. This makes it harder for hackers to gain access to your device, even if they have your password.

Most smart devices now offer two-factor authentication as an option, so be sure to enable it if it’s available.

Monitoring Device Activity

It is important to monitor your smart device activity regularly. If you notice any suspicious activity on your devices, such as devices turning on or off without your input, disconnect them from the internet, and contact the manufacturer or an IT specialist immediately. They can help you identify the problem and take the necessary measures to secure your device.

In addition to monitoring your device activity, it is also important to monitor your network activity. There are many tools available that can help you monitor your network traffic and detect any suspicious activity. PRTG is a free home network monitor that we can recommend.
