Seven essential security features for Linux based edge devices

Securing Linux OS in IoT devices is crucial against hacking and data breach but what are the main security features we must consider, well there are seven which we recommend..

Despite the delays caused by the COVID-19 pandemic, edge computing is expecting exponential growth over the next few decades because of developments in 5G and Internet of Things (IoT) technology. According to Statista, the number of IoT-connected devices is forecast to reach 25 billion in 2030, a more than threefold increase from 2019. Moreover, the worldwide edge computing market is projected to reach 250.6 billion USD by 2024.

The sheer number of IoT devices is mind-blowing, this means the security issues surrounding edge computers are numerous and complex. The hacking of a good spectrum of smart devices like smart fridges, baby monitors, vehicle infotainment systems is indicative of a security trauma caused hacking attacks.

Millions of IoT devices on the field requires a different set of security approach compared to traditional methods. Anyone can steal, copy, or hack if no proper security approach is implemented. It inherently becomes harder to secure edge devices with their challenging environmental condition.

Edge computing devices with operating systems are vulnerable to security threats that are different from traditional IT security environments like servers, laptops, desktop computers, and mobile devices. For example, transit operators are using Linux and Android-based smart devices on the field. In buses and railways, it is difficult to manage when the numbers scale above 1000 devices.

Here are the 7 pointers that every designer needs to consider while developing a network-based edge computing device.


Why and how to choose System on Module or Computer on Module?

“System on Module (SoM) is widely used in embedded product development. Why computing module will gain more popularity and how design teams can find the right fit.”

Robotics and Industrial automation are transforming the manufacturing industry by creating smart machines that are more efficient and productive. Manufacturers around the globe are implementing smart factory or Industry 4.0 systems to improve production output and reduce costs.

This surge in requirement of smart machines led to higher demand for embedded systems that have higher computing power with plug and play features, which created the demand for compact and powerful SoMs or CoMs. It allows for faster development and deployment of products in a cost-effective manner. SoM helps to launch the new product in the market sooner as compared to conventional methods. Moreover, using SoM enables the application of advanced technologies such as AI and ML to further improve productivity.

So, what is a SoM?
Going by the definition on Wikipedia, “System on Module (SoM) or Computer on Module (CoM) is a board-level circuit that integrates a system function in a single module. It may integrate digital and analog functions on a single board. A typical application is in embedded systems.”
