Securing Ubuntu Deployments for IoT and edge devices

Steps to maximise the security of Ubuntu-based devices

From manufacturing to agriculture, healthcare, logistics, and beyond, IoT devices are becoming increasingly common and critical in driving value across various industries. However, despite their widespread adoption, ensuring the secure use of IoT and edge systems remains a major challenge.

There is no silver bullet when it comes to security. Instead, the best approach is defense in depth (DiD), combining multiple layers of protection.

This whitepaper will address an essential security layer, whose key role is easily overlooked: your device’s underlying operating system (OS). We’ll discuss the easy steps you can take to secure your Ubuntu-based device.

This whitepaper details practical steps for securing devices on Ubuntu, including:

How to minimise the attack surface by disabling USB, IPv6, core dump, and other functionalities that are not in use.
Exploring unattended-upgrades to keep automatically up-to-date with the latest security vulnerability patches.
Mitigating brute force attacks through SSH hardening and firewall configuration.
