It is universal that modern-day gadgets and IoT devices make our home smarter. But it is all the more important to know how to secure our smart home. So in this article, we are going to see smart home security.
You may have smart home Internet of Things such as smart lock, smart door, ring doorbell 2, smart alarm, home security cameras, smart bulbs (Philips hue, Lutron), google home speaker, devices to control your TV (Logitech harmony, Google Chromecast, Amazon Fire Stick), Google nest, Vacuums, Plugs, Nest Thermostats etc.,
Google Nest is a brand of Google LLC used to market smart home products including smart speakers, smart displays, streaming devices, thermostats, smoke detectors, routers and security systems including smart doorbells, nest camera outdoor and smart locks.
These home security systems are very efficient and make our work easier during busy times. But IoT devices are like a double-edged sword. The price tag of IoT devices always notes high, and the possibility of harm is higher than good.
Like any other smart system, the IoT devices too make new entry points for the cybercriminals.
Internet Security Threat Report, 2017 published by Symantech says that IoT devices are being attacked once every two minutes(The Economic Times).
What are the different ways of attack in the Smart home security?
1. Man in the Middle Attack
The attacker spoofs communication between two devices. For example, the fake temperature data can be breached and sent to the cloud.
2. Identity Theft
The unsecured smart devices tend to provide sensitive data to the cyber criminals unknowingly.
3. Denial of Service attack
This makes the smart devices or network unavailable for the users. It floods the devices with unwanted data and makes the system unavailable. Unwanted or spam data are created by cyber attackers.
4. Device Hijacking
The attackers hijack and control the devices. Since they don’t change the basic setup of the device, it cannot be easily detected.
Ransom will be demanded by the hackers to unlock the devices. But there is no assurance that hackers will unlock the devices even if the ransom was paid.
Now, let’s see the cyber security challenges we may face in a smart home.
Cyber Security Challenges – Smart Home Security
Security cameras and routers are the main targets for cybercriminals as they don’t have high-security features.
If the software of the IoT devices is not updated, then they can be easily attacked by hackers.
The passwords of the system should be smart and intelligent. If default passwords are kept, the cybercriminals can hack the password easily.
Hence, we need to know the below mentioned basic security tips…
Tips to Smart Home Security
1. Mobile Security
As the smart home devices will definitely be connected with your mobiles, your mobile phones need to be secured.
You may get a lot of update notifications to download software for your connected devices. But you should act wisely during this time, and check the website of the updates and then download if necessary.
2. Router Name Secure our smart home
The name of the router needs to be changed. Don’t keep the router name which represents the make or model. Better to keep an unusual name for the router.
3. Keep strong passwords to protect all your devices.
Use strong and unique passwords that can’t be easily guessed by others. Do not keep the default or common passwords like, “abc”, “123”, DoB etc.,
4. Reconfigure the default device settings
Better change the default settings. Since most of the default settings are insecure, it is wise to reconfigure and use.
5. Disconnect the devices when they are not in use
Disconnect the devices or the whole network when you are away from home for a few days. You can connect them back whenever necessary.
6. Backup the data
If any device data is needed, then set up automatic backup or take manual backup.
7. Secure your WiFi
Implement a double encryption method on your WiFi. It will be helpful to secure your communication.
8. Enable the mandatory features
The IoT devices have a greater number of features. Disable the features which are not mandatory.
9. Don’t use public WiFi network
Don’t use the public WiFi network on your mobile when controlling your smart home devices. Cybercriminals may smartly hack all the data through public WiFi. Better use the Virtual Private Network (VPN).
10. Keep your software up to date
The version of your software should be updated as and when notified. This may avoid the attacker’s intrusion.
We have discussed smart home security and the cyber security challenges you may face. The tips provided may be helpful to secure your smart home and live happily.
