Linux maintenance: Best practices for embedded systems
Embedded Linux evolves at a rapid pace and keeping up with this development can be challenging for software development and maintenance teams. The maintenance of a Linux platform requires a significant investment of time from developers, which can limit company’s resources to innovate and bring new products to market. This article explores the critical aspects of Linux maintenance from embedded systems perspective and how manufacturers can effectively manage software updates, security vulnerabilities, and compliance with regulatory requirements.
The need for up-to-date software components
All hardware manufacturers should ensure that their embedded devices utilize up-to-date and secure platform software components. The lifecycle of these software components can be as short as a single quarter, necessitating daily follow-up of updates from developer community and manufacturers. These updates are often derived from upstream projects, bringing fixes and new features that enhance functionality and security. The “End of Life” situations for these components further intensify the need for regular updates, which manufacturers must proactively manage.
Responsibilities of manufacturers
For manufacturers utilizing embedded Linux, it is essential to maintain the software platform and implement updates effectively. This includes:
- Compatibility testing: Ensuring that all hardware components function seamlessly with the updated platform components.
- Vulnerability management: Assessing and mitigating the impact of publicly known exploitable vulnerabilities.
- Lifecycle management: Strategically planning of product lifecycle, including software updates and security patches.
The rate of change in platform components and the predictability of a product's lifecycle are increasingly critical. Given that most devices have data interfaces and may handle sensitive personal and financial information, compliance with regulations such as the NIS2 Directive, Radio Equipment Directive, and Cyber Resilience Act is paramount. Manufacturers are responsible for maintaining the security of their devices throughout their entire lifecycle and reporting vulnerabilities and security incidents to authorities.
The importance of security in critical sectors
The need for robust security maintenance is important especially when devices are used by essential and important entities that operate in critical sectors such as energy, transportation, healthcare, IT and telecom, and manufacturing of chemicals and electrical equipment. In these areas, the stakes are high, and any lapse in security can lead to incidents with significant consequences.
