How to secure IoT on home network? (Secure Smart Home!)

The use of IoTs expanding rapidly. This usage makes our lives and daily tasks much more productive, easy, and time-saving.

There are many lots available for different tasks. Each IoT has its own specified task. For example, a smart thermostat learns our interaction behavior and sets the temperature accordingly to save more energy annually.

But this over-demanding usage of these IoTs also raised some concerns. So, before jumping, why should we isolate IoTs from the home network; let us understand how these things work.


Internet is known as a worldwide connection between people.

Internet is a new global network system that helps in our daily activities. These activities are communications, research, jobs, video games, and much more.

The Internet looks for a wide area of our works and assignments. Many help services are available on the internet. Internet is an entire world in itself. Internet covers all of our activities; from our education to entertainment, from news to research.

Summary: the internet is an established global communication network that provides a vast variety of smart information and facilities.

The Internet has revolutionized the 21 century through its uses and benefits to human life. It helps in working statements of a person. These statements can be help services, smartphone applications, media streaming, and social media.

Internet helps to communicate and serve the purpose of making our life easier. The Internet makes things work fast and effectively. It is cheap and free of mistakes.

Many devices can be attached to the internet for our convenience. These devices help us in our daily activities. These devices are known as IoT devices or the internet of things.


Internet of things makes our life easier and faster. 

IoT is an advanced system of devices that connects or establishes a connection to the internet. It can be any computing technology or device that can be mechanical or digital machines. 

Internet of things or IoT is helpful for our houses and businesses. Internet of things has also advanced our agricultural society and organizations. 

IoTs have automated the processes of many businesses organizations and companies. They have reached advanced levels with the help of the internet of things—as it improves the quality of work services. These devices are less expensive and cause no malfunction.

Internet of things or IoT helps in transferring data that can be without human interaction.

To conclude this, we can say that the internet of things or IoT is an ecosystem that consists of those smart devices that help us in our daily activities. 

Internet of things can include devices and technologies such as sensors or any hardware device which can collect and send data over to the network and we can use it anytime.

How do IoTs work?

Every IoT device is programmed for a single task; for example, a smart camera can record, and you can live stream on your mobile phone.

 It needs stable Wi-Fi to do so.

We connect it with the internet and power. Then it can send data back to the mobile application and we can use the same application to communicate back with the camera.

So, the internet is the primary part of these devices.

Importance of IoT

Internet of things has restructured our businesses, industries, homes organizations and many other areas of human life. These small devices are not just ordinary devices, they have paved the path towards success and advancement in the future. 

  • These devices let us connect to our home all the time with our cell phones.
  • It is easy to connect IoTs to make a network of devices that are handling our daily tasks.
  • IoT is utilized to improve our business strategies and processes because it makes things work faster.
  • Internet of things improves customer services, and it makes no mistakes.
  • It helps to improve the quality of employee productivity through the use of IoT devices.
  • It helps in business decisions.
  • Our agricultural sector and other organizations receive significant benefits from the internet of things.

Establishing Different Networks For IOT Devices

Internet is one of the largest network systems in the world which is used for the convenience of human life. But the Wi-Fi network can sometimes result in a headache for us. 

Wi-Fi holds our security and privacy, and IoT devices are the way to our professional and personal lives. Our smart devices which are connected to the Wi-Fi internet connection hold our information that can be hacked. 

Internet may help people in everyday tasks but it can be vulnerable. 

Therefore, we must establish a separate Wi-Fi network for our IoT devices and smart home devices. These devices hold our private information, which has the chance to be cyber-attacked. 

If we have multiple IoT devices at our house and all of them are connected to one router or one Wi-Fi network, then we can say it has the chance to be hacked. The cyber attackers can get to our router from which our personal information or privacy can be invaded. 

To be on the safe side, we must separate our networks and devices into two parts. One network can be utilized to form a connection to all of our IoT devices and another network for our personal use.

FOR EXAMPLE: We should have a separate Wi-Fi network for our fridge and our laptop. This will protect us from any vulnerability and cyber-attacks.

What Happens If We Use The Same Wi-Fi Network?

Internet of things or IoT devices is increasing day by day because of their usage by popularity. The producers or the manufacturers of IoT devices are under a lot of pressure because of their increased usage. 

They are in a rush to produce IoT devices with little effort to make them secure from any sort of vulnerabilities. If we use the same find network connection for the IoT devices and other devices, we can be open to vulnerability.

FOR EXAMPLE: If a hacker gets access to our heating or lighting system, he can easily find out if we are away from home according to its usage. 

If you use Amazon echo with voice commands, the hacker can know or have access to our passwords or unexpected bank account because we share our information with the Amazon echo .

Why to isolate IoT devices from the home network?

Because every device connected to the internet is a potential target for hackers and reaching the device via the internet is a common practice.

Changing the WiFi network for these internet-connected devices is a smart practice. When any hacker wants to hack your smart devices, he will try to figure out your home network to reach to the device, but at the same time, you are using a different one than your IoTs.

In this way, the hackers will bumble to discover your IoT network .

Isolating IoT devices on the home network

There are many possibilities to save your IoT devices and other devices from hacking. All we require doing is to use both of the things on separate Wi-Fi networks. We can accomplish so by establishing the following steps:


We can set two different internet connections on a single router. This is the most reliable alternative.

We can use up to four networks on a single router. The best way is to set up different, multiple LANs to form a subnet and we can say that we can use VLAN on a personal network. 

For more accurate protection, you can buy internet connections at home; one for IoTs and the second for your usage.


Many routers allow us to create a guest network in one router. Log in to our router and access the settings in which we will find the guest network.

When the option of the guest network is selected, it opens a new network. Therefore, it can be used as a personal network. The name and password should be strong. 


We can buy two different routers which can be paired with one internet connection. For this, we have to require proper configuration and connections. This way is complicated and provides less security. This way is better than using only one network for these devices and other devices.

We can invest in a Wi-Fi management tool, which is an excellent practice to secure our smart devices and regular devices. We can use an internet management tool, which is Optim . It will do all the work of security for us. 

Optim is easy to use. If there is any problem with our Wi-Fi network optim can use machine learning algorithms. ML algorithms will be used to identify any problems and fix them automatically.

Should We Use IoT Devices On A Guest Network?

We can use IoT devices using guest network, but it will cause some issues for other smart devices later.

Many IoT devices have to be part of our home network to work properly. Many of them do not work correctly when part of a guest network. When we add our IoT devices to the guest network, it makes them invisible for our other devices to be used. 

Connecting IoT devices to the guest network means that we are disconnecting them from our local network. 

FOR EXAMPLE: If we connect our printer to the guest network, it will make it invisible to our other devices. When going for the print option, we cannot find the name of our printer that cannot print. 

Therefore, it is crucial that we only connect that internet of things or IoT devices to the other guest network that only needs the internet to work. They will work perfectly when we put them on an isolated guest network.


To the system, we can say that IoT devices help us in our daily activities. They are smart devices that make our life more comfortable and store data. 

These devices have helped in the development of many organizations, businesses, and agricultural advancements. 

Nevertheless, IoT devices also come with one disadvantage, and that is being hacked. You can ignore this disadvantage but take measures two separate power IoT devices and other devices. It will save our privacy and keep us out of any kind of vulnerability.
