Smart TV Security: Understand the Risks and Protect Yourself from Gaps

Smart TV is one of the main devices of the recent Internet of Things that has entered the home of users. While offering new features such as streaming applications, social networking, online games and Internet browsing, you must also take care of your security, as well as other devices connected to the network and used on a day to day basis.

According to experts from ESET security company, smart TV should be treated as a computer, since hackers do not have to access the equipment physically to attack. In addition to installing malicious and spying apps, intrusions can access files and even reach other devices on the network, such as notebooks.

Tests by Consumer Reports in the United States, with five branded smart TVs and different operating systems have revealed that current models are susceptible to attack. There are breakthroughs for intrusions from the most inoffensive ones - such as to change channels and increase the volume of the television - to the most dangerous, which install malicious applications and disconnect the device from the Wi-Fi remotely.

While there is no antivirus available in the market to shield smart TVs, check out six tips below that can help protect your data. Options include simple, routine tasks such as careful connecting to an unknown Wi-Fi and checking for external devices that will be connected to the TV.

1. Enable automatic updating of Smart TV

In the Smart TV settings, keep the automatic update selected

Most smart TVs offer, in the settings, the automatic firmware update option. The feature allows the device to receive, for example, security optimizations as soon as it is sent by the manufacturer to enhance the protection of the equipment and the operating system.

2. Avoid connecting to Smart TV on unknown Wi-Fi networks

Just like using smartphones and notebooks, it's important to be aware of the Wi-Fi that the smart TV is connecting to. In an area with many apartments or offices, for example, open networks can be identified by the television. The ideal is to use your own Wi-Fi, with a password, to prevent intrusion.

3. Ensure that the router has a security protocol

Wi-Fi router must have WPA2 security protocol to enhance protection

The Wi-Fi router in the home or office where the smart TV is also must be configured securely. For this, the use of a device with WPA2 protocol, available in current models is indicated. The feature offers enhanced protection, less susceptible than WEP encryption of old equipment.

4. Check the security of external drives and hard drives

As with other devices, before connecting a flash drive or external HDD to smart TV to open files, movies or music, it is important to check if the devices are free of viruses or any malicious documents. It is possible to carry out the process with anti-malware software on your computer, which should always have an antivirus installed to ensure protection at all times.

5. Avoid shopping through the device

Even if smart TV allows browsing the Internet, entering shopping sites and carrying out transactions, users should avoid paying bills on the television, as it is not yet a fully secure device - it does not have the SSL verification system, which checks if a web page is reliable. In case of requesting personal or bank data, prefer to use a notebook or PC with antivirus installed.

6. Avoid clicking suspicious links

Another rule that also works for smartphones and computers is not to access suspicious links that appear in emails, applications or websites. Before clicking any address make sure that the platform that made it available or who sent it is trustworthy. Otherwise, prefer to access by a more secure device.
