An unsafe smart home device becomes a point to easily penetrate your home network. From here, hackers can launch attacks and steal your data from within the network. The consequence is very catastrophic, but you can protect your smart home devices before they are infringed.
Change the username and default password of the manufacturer
Most smart home devices have a default password when you buy them. The default password is simple and easy to remember, allowing users to access the admin account when setting up the device. However, many of us forget to change these default passwords, making our networks easily attacked. It is important to change the default password to a strong, safe and unique password. When selecting a password, you can use tools like Omni Calculator to check the strength of the password.
Some threats, such as attacking Brute Force and Rainbow Table, can crack the password for a few seconds. Therefore, to increase a protective layer, you can set up multi -factors authentication (MFA) for your device. The best multi -factor authentication applications can help keep your device safe.
Use biometric authentication
Smart home devices such as smart home alarm system, smart lock (especially for limited areas of your home) or smart devices containing sensitive financial information will be enjoyed. benefits from biometric authentication.

Instead of a password that can be unlocked or forgotten, biometric authentication uses a biological characteristics of a person such as fingerprints, voice or facial recognition to control access. The biometric characteristics are difficult to counterfeit and are unique to each individual, so they are safer alternatives to traditional identity verification methods.
Use guest network for smart home devices and limit access to equipment
The separation of smart home devices can enhance network security by isolating them from the main network. If your smart home device is violated, segments can make it difficult for hackers to access other devices. This limits the damage in case of being invaded. PCs, laptops, phones and other important data storage can be safely connected to the main network. The network of guests can separate smart home devices with stronger security features.
You need to limit and control those who are allowed to access your smart devices. Using the minimum privilege principle (Polp), limiting access to a small number of people or controlling access to some people, such as limit what they can do to a minimum (or Only what they need), will reduce the surface of the network attack.
Turn off the equipment features that you do not use
Turn off features such as videos, audio, bluetooth, geographical navigation and other features that you do not usually use will limit the data that the device collects and stores. It also reduces the attack surface that hackers can exploit. For example, Bluetooth off will reduce the risk of targeting various Bluetooth attacks such as Bluesnarf, Bluesmack DOS or Blues Dump.
You should turn on the lock screen of the device to prevent unauthorized access to your device. Shorten the locking time to automatically lock when the device is not touched for a few minutes. Instead of passwords, use the lock, may be more unpredictable. To add another layer of security, reduce the number of tests allowed so that data thieves can only guess a few times.
Turn on software updates and automatic firmware
Devices are not designed with automatic updates that need to be checked manually. Patches and updates are designed to solve security holes and installing them as soon as available will help reduce the risk of targeting. Make sure you download updates or patches from the manufacturer's official websites. Illegal updates from unofficial websites can carry malware, spyware or advertising software.
