Smart TVs and IoT (Internet of Things) devices have transformed modern homes, providing convenience, automation, and entertainment. However, their internet connectivity also makes them vulnerable to cyberattacks. Many users overlook security configurations, making these devices easy targets for hackers who can steal data, spy via cameras, or gain access to the home network. Securing these devices is essential for protecting privacy and ensuring a safe digital home environment.
Most devices come with factory-set credentials. Change these immediately to strong, unique passwords to prevent unauthorized access.
Regularly check for and install updates from the manufacturer. These patches fix known vulnerabilities that hackers may exploit.
Turn off features like voice recognition, remote access, or Bluetooth if not in use. This reduces the device’s attack surface.
If the device or its connected app supports 2FA, enable it for an added layer of security during login attempts.
Use strong encryption (WPA3 or at least WPA2), hide your SSID, and create a separate guest network for IoT devices.
Place IoT devices on a separate network from your main devices (like phones and laptops) using VLANs or a dedicated router.
Use a firewall to monitor network traffic or install compatible security software on devices that support it.
Powering down unused devices reduces exposure and energy consumption.
Only control your smart home devices through secure, private networks.
Limit data collection and sharing features, and monitor what information the device is accessing or transmitting.
Infected devices can be used in large-scale cyberattacks (e.g., Mirai botnet).
Smart cameras or voice assistants can be hijacked to spy on users.
Personal data, login credentials, or browsing history may be collected and misused.
Hackers can take full control of devices, locking users out or manipulating settings.
A user buys a smart TV and connects it to their home Wi-Fi. Over time, they begin noticing unusual pop-ups and sluggish performance. It turns out the device was compromised due to outdated firmware and a weak default password.
Installs the latest software update released by the TV manufacturer.
Replaces the default credentials with a strong, unique password.
Turns off voice control and automatic data sharing.
Sets up a separate guest Wi-Fi network for all IoT devices.
Uses the router’s built-in firewall to monitor traffic and block suspicious activity.
Uses the companion app with two-factor authentication for added protection.
