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.
