Embedded systems and their use is growing day by day due to their usage in IoT and many other applications. Many people use VPNs to secure their data and information, but do VPNs work on embedded systems?
Do Embedded systems allow their usage just like windows VPN? This is a bit tricky question because embedded systems are something used by researchers, scientists, and engineers. Unlike regular computers, there may not be tons of open source guides related to such systems.
However, in this article, we will learn whether you can use a VPN on an embedded system such as a raspberry pi or not. And what will be the benefits of using a VPN on a raspberry pi? With that said, let’s not waste any more time and get into it!
What are Embedded Systems Used For Mostly?
Before we learn about the use of a VPN on an embedded system let’s have a brief discussion about these systems and their usage.
An embedded system is a computer system with a dedicated function within a larger electrical or mechanical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in everyday use today.
The program code for an embedded system is stored in read-only memory (ROM) or flash memory so it cannot be modified after manufacture.
Some examples of devices that use embedded systems are:
- Automobiles – engine control, anti-lock brakes, traction control, airbags, entertainment systems
- Appliances – washing machines, dishwashers, refrigerators, microwaves
- Avionics – aircraft control and navigation, air traffic control
- Biomedical – pacemakers, heart-rate monitors, glucose meters
- Communications – base stations for cellular networks, private branch exchanges (PBXs), Voice over IP (VoIP) phones
Can You Use a VPN in an Embedded System?
Now that we know what an embedded system is and some of its usage, let’s get back to our main question. The answer to this question is a bit tricky because it all depends on the type of embedded system you are using.
For example, if you are using a raspberry pi, then the answer is Yes! You can use a VPN on a raspberry pi because it is a full-fledged Linux system. So, you can install any type of software on it including a VPN client.
On the other hand, if you are using an embedded system that doesn’t have an operating system or only has a very basic one, then the answer is No! You cannot use a VPN on such systems because they cannot run any type of software.
However, even if you can use a VPN on an embedded system, some devices don’t allow VPN traffic. So, you need to make sure that your device supports VPN traffic before trying to use a VPN on it.
What Are the Benefits of Using a VPN on an Embedded System?
There are many benefits of using a VPN on an embedded system. Some of the most notable ones are:
- It increases the security of your data and information as it encrypts all the traffic passing through it.
- It allows you to access websites and services that may be blocked in your country.
- It allows you to remain anonymous online and prevents your ISP from tracking your online activities.
- It can help you bypass firewalls and network restrictions.
So, these were some of the benefits of using a VPN on an embedded system.
Last Minute Thoughts
The use of Embedded systems is growing day by day. And with the growth of these systems, the need for security is also increasing. A VPN is one of the best ways to secure your data and information when using an embedded system.
But before using a VPN on an embedded system, you need to make sure that your device supports VPN traffic. Otherwise, you won’t be able to use a VPN on it.
So, that was all about the use of a VPN on an embedded system. We hope this article cleared all your doubts and questions related to this topic. If you still have any queries or suggestions, feel free to contact us in the comments section below. Thanks for reading!
