The emergence and recent advancements of IoT technologies keep moving far, creating smarter ways for operating and optimizing devices.

IoT is one of such technologies helping to build a reliable network of data transference across multiple devices.

As IoT keeps making smart connections over a wide range of distances, there is an increasing need for IoT device security. 

Are you wondering if it’s really important to give your IoT devices some protection?

Or you conclude such device security is not just your thing?

I’m sure don’t want to have unwelcomed guests into your home appliances before you eventually consider a quick protection.

That popular sense of security accompanying smart devices is only an unverified assumption. You don’t want to leave your IoT devices to such unfounded conclusion.  

Why Must You Protect Your IoT Devices?

Experts in cybersecurity conclude that all IoT devices can be hacked.

That’s an ‘all’ with the exclusion of none!

Also, according to Tulane University’s Information Technology Programs Coordinator, a slight vulnerability on an IoT device is just sufficient pathway to allow hackers in.

If such vulnerability can cost that much loss, no efforts on how to protect your IoT devices from hackers can be regarded as unnecessary. 

While IoT devices are inter-linked to serve big picture purposes, their ultimate goal is meeting human needs.

So, its’s good to say humans are directly at the center of these IoT devices in some way.

This thought clearly explains the importance of protecting your IoT devices – to significantly reduce human associated risks. 

There are many ways through which hackers can get into your devices.

Most common of these include (but not restricted to) data breaches, surveillance camera access or some, identity thefts and hacked digital privacies.

However, a pre-planned smart security strategy can be trusted to keep hackers barred from all your IoT devices.

9 Safety Tips to Protect Your IoT Devices from Hackers


Here, you will learn the easiest ways on how to protect your IoT devices from hackers. We have shared 9 tips on how to do that.

1. Ensure A Proper Wi-Fi Router Set-Up

Purchasing your router and successfully setting it up are the first two primary steps for smart IoT device security. This is because your router is at the heart of all your connected device operations.

Network set up involves creating a name which does not have to link with your personal information. That name should often be a designation via which hackers will find it difficult to spot on your location. This is exactly where the security mentality comes in.

While making your router set up, it is also important to adjust your network settings to ‘out of view’ so you can get off a hacker’s radar. 

Apart from network settings, your router password is next in line. Here, you’ll need a blend of characters including letters, symbols and numbers to create a strong password. Lastly, a fully secured Wi-Fi encryption is a way to complete your router set up.

You can find the summary of guidelines for a suitable router set below.

  • Customize your secure router name by changing default router details
  • Create a highly unique router password
  • Upgrade router encryption 

2. Create Individual Passwords for Your IoT Devices

Each IoT product you purchase has its default account details directly from manufacturers. You need to create special passwords for them too.

Interestingly, this is something easy you can do by yourself with no hassles.

If you have many such devices, a smart password manager will be perfect to remember each device’s password. 

3. Update Registration of New IoT Devices 

Registration of each IoT device is a good way to protect them.

Even though this seems unnecessary after you have made a purchase, it is still highly recommended regardless.

Registered products receive frequent updates on software, which consequently helps to reduce risks associated with device security.

That is the advantage registration affords you against hackers. 

4. Avoid Access to Unused IoT Devices

One easy and quick way to ensure security is disconnecting all unused devices at the times their functions are not presently required.

Unplugging unused devices makes them undiscoverable to hackers while it also reduces your energy billings. 

5. Disable IoT Unused Device Features

Just like you don’t always have to use all smart home devices, there are also some features that are not always particularly useful to you every time.

Disabling some of the features when they are not needed really helps to protect your device. 

6. Protect Your Device Using the Multi-Factor Authentication

If you are still wondering exactly how to protect your IoT devices from hackers, I have some other tip for you.

There is an added security awareness that you experience using the two-factor authentication.

How does this work?

It protects your device by requesting for multiple levels of access details. It does this by requesting intending user to provide added information as evidence of their identity.

This is such a great way to knock off hackers. 

You can ensure this function using special verification codes just like in the case of your mobile banking.

This is really a trusted step because such verification code gets delivered via your phone or email.

That way you can be aware of any form of access into your IoT devices. 

7. Avoid Public Wi-Fi Connections

It is always a good idea to avoid public Wi-Fi networks especially when they can’t be trusted.

Your best alternative when you are in public and need to connect your IoT devices is using a VPN to ensure security. 

8. Upgrade Device Firewall

You sure need an upgrade of old firewall protection to protect your IoT devices from hackers. This upgrade to Next-Generation Firewall (NGFW) is very important so as to ensure better protection. 

9. Ensure Proper Device Disposal or Transfer

Lastly, you may have forgotten to do proper data reset or removal before giving off your device or even disposing them.

That might automatically give a hacker easy access to your information.

So, make sure to remove all your information on the device before releasing it. 


While it is true that IoT devices have varying levels of vulnerability, it is still very important to consider giving each one of them a high level of protection.

Going the extra mile on how to protect your IoT devices from hackers is a rewardable resolve.
