Why smart home devices are vulnerable?
Home routers and security cameras are the main internets of things targets of hackers. Why? Because - like most other connected devices - they have little built-in security.
There is another reason. Security is often not the top priority for IoT device manufacturers. Their poor safety practices may include:
Without system reinforcement.
There is no update mechanism to create a vulnerability.
The default password or hardcoded password that hackers can use.
Lack of system reinforcement.
No update mechanisms, creating vulnerability.
Use of default passwords or hardcoded passwords that hackers can use.
How to build a more secure smart home?
Start with your Wi-Fi router to build a safer smart home. This is the base project for connecting all connected devices and making them operational.
Tips for making your smart home safer
1. Give the router a name.
Do not insist on using the name provided by the manufacturer - it may identify the brand or model. Give it an unusual name, regardless of you or your street address. You do not want the router name to reveal any personal identifiers.
2. Use a strong encryption method for Wi-Fi.
In router settings, when setting Wi-Fi network access rights, it is best to use strong encryption methods such as WPA2. This will help to ensure the security of the network and communication.
3.Set up a visitor network.
Keep your Wi-Fi account private. Visitors, friends, and relatives can log in to a separate network that is not tied to your IoT device.
4. Change the default user name and password.
Cybercriminals probably already know the default passwords that come with many IoT products. That makes it easy for them to access your IoT devices and, potentially, the information on them. Are you considering a device that doesn’t allow you to change the default password? Then consider a different one.
Cybercriminals may already know the default passwords which makes it easy for them to access your IoT device and possibly the information in it. So, we need to change the default user name and password.
5. Use a unique strong password for Wi-Fi network and device accounts.
Avoid using common words or passwords, such as "password" or "123456". Instead, use unique, complex passwords that consist of letters, numbers, and symbols.
6. Check the setting for your devices.
Your IoT device may come with default privacy and security settings. You may need to consider changing them because some of the default settings may benefit manufacturers more than they do you.
7. Disable features you may not need.
Internet of things devices come with a variety of services, such as remote access, which is usually enabled by default. If you do not need it, make sure it is disabled.
8. Keep the software up to date.
When your smartphone manufacturer sends you a software update, do not delay installing it. It could be a patch for a security vulnerability.
9. Audit the IoT devices that already exist in the home network.
It's time to upgrade the old security camera. Take the time to check if the new model offers greater security.
10. Perform two steps.
We are talking about authentication. Two-factor authentication, such as a one-time code sent to a mobile phone, can keep bad people away from your account. If your smart device app provides dual authentication or 2fa, use it.
11. Avoid public Wi-Fi networks.
You may want to manage IoT devices through mobile devices in coffee shops all over the town. If you use public Wi-Fi (usually not a good idea), use a VPN.
12. Be careful of power failure.
Make sure the hardware interrupt does not cause the device to be unsafe.
There is no doubt that there will be more Internet of things devices, and they will occupy a place in your home. If they make your life more convenient - or even happier - then better. But don't forget to protect your increasingly intelligent home and Internet of things devices.
