If we look at the use of technology in corporate affairs, there are very few technologies that have penetrated as deeply as the Internet of Things (IoT). From finance to marketing to operations to security, almost everything has been affected by this new technology, and IoT devices exist in the market to help companies with all these functions.

Therefore, it’s not surprising that many companies have adopted those devices to streamline various business operations. Research firm Global Data has forecast that by 2023 the global IoT enterprise market will be worth $318 billion from the current $130 billion recorded in December 2018. So, if your company is also adopting IoT, you’re among those entrepreneurs who are racing ahead with changing times.

However, using IoT devices also has a few challenges. When you deploy IoT devices at a large scale in your company, it also becomes crucial to pay some special attention to the security of those devices.

And we’re here to help you out with that. We’re going to tell you about seven simple steps that you can take to boost the security of your IoT devices. Here we go:

Setup IoT Security Analytics

A few security threats can be kept away if you set up security analytics for the IoT devices operating in your company. Once implemented, IoT security analytics allows security service providers to collect and examine data from various devices that are part of your company’s network.

This analysis of data then helps in identifying and fixing potential security threats before they can create any big trouble for your company. Therefore, implementing reliable IoT security analytics is one of the first steps that you can (and should) take to increase the security of your company’s IoT devices.

Check Credentials Being Used

Use of generic login credentials (i.e., usernames, passwords, etc.) is a recipe for disaster in cybersecurity. Whenever botnets start looking for vulnerabilities in a corporate network, exploiting generic login credentials is the first thing they do.

So, check the credentials of all IoT devices deployed in your company’s network, and ensure that none of them are using generic login credentials.

Use Trusted Platform Modules (TPMs)

Impersonating or cloning is a popular method used by hackers to steal almost anything in the world of computers. From web servers to mobile numbers to users’ identities – everything can be cloned, and once they’ve been cloned, it becomes easy for a criminal to steal sensitive information from them. IoT devices are no different.

They can also be cloned, and that’s why you should use a TPM. TPMs are special microprocessors that assign a unique identifier to every IoT device for its identification and encrypt that identifier with cryptographic keys to ensure that it’s not spoofed. That way, a TPM helps in preventing the cloning of IoT devices.

Updates

Software updates are essential for network security, and IoT devices are also not exempt from this basic rule. Keep software of all your IoT devices as up to date as possible, because it helps in ensuring that security vulnerabilities are fixed in time.

If there is an update by an IoT device vendor, ensure that it’s installed as soon as possible. Tell your IT department to put this thing in their priorities.

Use Encryption And Public Key Infrastructure (PKI)

Encryption is essential for both end transfer (browser to the server) as well as storage of sensitive data. If IoT devices in your company deal with data of confidential nature, then encryption is necessary for them as well.

If they source sensitive data from your website, ensure that your site is secured with an SSL Certificate. Also put in place a proper Public Key Infrastructure – or PKI, as it’s popularly known.

PKI refers to a set of policies, hardware, software, and procedures that are used for the management of digital certificates. It ensures the security of data being transmitted by IoT devices by utilizing both symmetric and asymmetric methods.

In symmetric encryption, both encryption and decryption of data are done with the same key. While in asymmetric encryption, different keys are used for encryption and decryption (encryption with public key and decryption with private key). PKI ensures that the right type of encryption mechanism is used in the right place, and no data is leaked to any 3rd parties.

Assess The Devices

It’s essential to assess all devices that are involved in the company’s network timely. Just as company accounts are audited quarterly to ensure that everything is going on in the right manner, all devices in the network of a company – including IoT devices – should also be assessed.

It ensures that they’re working without posing any risk to your company. If you have an IT department, ensure that they’re doing this. Otherwise, you can hire someone who can do it for you.

Put Telecommuting Policy In Place

If your company allows telecommuting, putting a proper telecommute policy in place is also crucial for the security of your IoT devices. That is because many times the mistakes of your employees can be suicidal for the protection of your company.

For instance, they may use a public Wi-Fi network to work on your official assignments, and your crucial data may get stolen by someone on that network.

Similarly, they may also use their personal computers for accessing some of your work-related files from the company server, and if their computer has some malware, then data downloaded on it from the server of your company will also be at risk.

Such mistakes can be costly for your company because once any virus has infected any device in your company’s network, it can also expand its reach very quickly to other devices through IoT devices.

Don’t allow it to happen and put a proper telecommuting policy in place that ensures the security of your work environment. You can take the help of cybersecurity professionals to draft that policy.

Conclusion

So, these were seven simple steps that can help you in ensuring the security of your IoT devices. Viruses and malware spread very rapidly in work environments that have IoT, so it’s necessary that we pay special attention to the security of our IoT devices. And now you can do that job very well by following these steps. All the best!
