The Role of VPNs in Safeguarding Internet of Things (IoT) Devices

Introduction

The introduction of ‘Internet of Things’ (IoT) into the mainstream consumer market is a giant leap forward in how people interact with machines and its use in everyday life. IoT devices are sophisticated pieces of technology capable of connecting and sharing data across multiple platforms. With the increased reliance on these devices and the inherent data that comes with them, it’s important to consider ways to protect this information from potential malicious attacks. One such way to protect this sensitive data is to employ virtual private networks (VPNs). VPNs are encryption-based technologies that offer a secure connection between two or more private networks over an untrusted public network and relay the communications back and forth in an encrypted format.

What are the Benefits of a Private Network?

One of the biggest benefits of using a private network is the added layer of security it provides. When an IoT device is connected to a VPN, it’s virtually undetectable to outside observers. This is because the data that is sent and received is ‘hidden’ within an encrypted format which is almost impossible for anyone to crack. By using a private network, the data that is being shared is not just protected from malicious attacks but also from spying and surveillance by government agencies as well as companies wishing to collect information about their customers.

Furthermore, a VPN can help users reduce the load on a single router, by allowing them to connect multiple devices to the same network, thus creating a more robust network and allowing for efficient data transfer. This in turn, helps improve the performance of the devices and reduces the bandwidth needed to transfer data.

How Does a VPN Protect IoT Devices?

The security of any IoT system is heavily dependent on the security of the data transmissions and communications within its network. If a malicious actor is able to gain access to the private network containing IoT devices are connected to, the whole system can be put at risk. By utilizing a VPN, the data transmission within the network is protected by strong encryption which is almost impossible to break. Furthermore, a VPN can provide an additional layer of authentication in the form of a two-factor authentication which requires the user to enter a unique secret code when accessing the system.

Also, since VPNs are capable of obfuscating a user’s web traffic, they provide an effective way to hide an user’s IP address. This makes it harder for malicious actors to track down the location of a device, thus increasing the overall security of the system.

What are the Challenges of Using a VPN?

Although VPNs are incredibly effective at providing a secure connection, they are not without their challenges. One of the biggest drawbacks of a VPN is that it can sometimes be slow. This is because of the added steps in the encryption process which can slow down the connection. That said, there are steps which can be taken to minimize the performance impact of a VPN.

For instance, using specialized hardware such as the Assemble T6X – a system specifically designed for high performance VPNs – can help improve the speed and performance of the connection. Additionally, providers such as NordVPN are now offering specialized servers specifically designed for streaming and other high-bandwidth activities, which can also help improve the performance of the connection.

What Additional Security Measures are Necessary for IoT Devices?

Aside from VPNs, there are several other security measures that can be taken to further secure IoT devices. It’s important that users only connect devices to networks they trust, and have adequate firewalls in place to protect against unauthorized access. Additionally, its important to keep all the devices connected to the network up to date, as attackers are always on the lookout for vulnerabilities in outdated systems.

Furthermore, it’s essential that users regularly change passwords on devices, as well as set up strong authentication such as two-factor authentication. Finally, users should consider using a content filtering system to control which websites and applications the devices have access to.

How Can Enterprises Utilize VPNs for Business?

For enterprises wishing to extend the security of their private networks into the public IoT space, VPNs can provide an effective tool. For instance, a VPN can be used to reliably and securely connect an office’s private network with its connected devices, including those on the public IoT. For enterprise networks, VPNs can provide an additional layer of security by encrypting all the data that is transmitted on the private network, as well as providing dual factor authentication protections.

Furthermore, enterprises can deploy multiple VPNs for different use cases, thus providing an additional layer of security. For instance, an organization can deploy a VPN to provide secure access to its corporate data, such as customer records, and a separate VPN for secure connections to its private IoT devices.

Best Practices For Securing IoT Devices

When it comes to securing IoT devices, there are some best practices that organizations should consider adopting. Firstly, it is essential for organizations to create and enforce an internal policy that outlines the use of IoT devices on the network. This policy should include guidelines on access permissions and security measures, such as the use of two-factor authentication.

Secondly, organizations should regularly update and patch the software on all connected devices to ensure that any vulnerabilities in the system are addressed. Additionally, organizations should use a content filter for all their IoT devices to ensure that these devices are not accessing any malicious websites. Finally, organizations should also consider investing in a VPN service to provide an added layer of security and encryption for all their data transmissions.

Conclusion

In conclusion, virtual private networks are an effective tool to secure the data transmissions from IoT devices. By employing a VPN, organizations can ensure that their data is protected from malicious actors, while still maintaining the privacy of its customers. With the number of IoT devices being connected to public networks steadily increasing, it’s important for organizations to take all the necessary steps to protect their data and their customers.
