Impact of Debian 10 EOL on Security and Compliance

December 28, 2023 - TuxCare expert team

  • Debian 10 will reach the end of life on June 30, 2023
  • Vulnerabilities found after the end of life will remain unpatched
  • TuxCare’s ELS for Debian 10 extends the lifecycle by 4 years

Debian 10, known as “Buster,” was first released on July 6, 2019, featuring numerous updates and improvements. Since then, Debian 10 has been a reliable Linux distribution for many enterprises and individual users. However, the security support for this version of Debian is coming to an end, with Debian 10 reaching its End of Life (EOL) soon.

This article will explore how Debian 10 EOL affects security and compliance, while providing strategies to mitigate potential risks.  


Understanding Debian 10 End of Life (EOL)


Debian Security Support for Debian 10 ended on September 10, 2022. However, it benefits from Debian Long Term Support (LTS), which extends the lifecycle of all Debian stable releases to a minimum of 5 years. Therefore, the EOL date for Debian 10 is June 30, 2023. 

The Debian LTS project is handled by a different group of volunteers and companies rather than Debian itself. After the Debian Security team, the Debian LTS team takes responsibility for the ongoing security maintenance of the different releases. This LTS coverage is only applicable to the i386, amd64, armhf, and arm64 architectures.


Security Challenges


The end of support for Debian 10 poses serious security risks for businesses and organizations. Without security updates, vulnerabilities found after the end of life will remain unpatched, making systems more susceptible to exploitation. As security threats evolve, using an outdated operating system is a recipe for disaster, potentially leading to data breaches and jeopardizing system integrity. 


Compliance Concerns


For businesses and organizations, complying with industry standards and regulations is crucial. Compliance frameworks often mandate the use of systems with the latest patches applied in order to ensure data security and protect consumers. Failing to comply may result in legal penalties and reputational harm to organizations. 


Mitigating Risks of Debian 10 EOL


Although there are challenges associated with the Debian 10 lifecycle ending, there are methods to prevent potential risks:


Upgrade to Debian 11


With Debian 10, your only possible upgrade is Debian 11 (Bullseye), which is supported until June 30 2026. After that, you can also upgrade to the latest release, Debian 12 (Bookworm). Both versions offer the latest security updates, bug fixes, and improved features, contributing to a secure and seamless computing environment.


Extended Lifecycle Support


Upgrading can be painful for businesses and organizations, as it can break the system and cause other sorts of disruptions. So, migrating to a new Debian release should be done with comprehensive planning and testing. If you still have not planned a migration, then it is already time to think about your roadmap, as the Debian 10 EOL date is approaching.  

In the meantime, you can opt for TuxCare’s Extended Lifecycle Support (ELS) for Debian 10, which offers a cost-effective option to extend the security lifecycle of Debian 10 for an additional 4 years. It gives you enough time to plan a migration to Debian 11 or newer versions while also receiving the vulnerability patches that cease after the end of life. Signing up for ELS for Debian 10 will ensure your systems remain protected from high and critical vulnerabilities and comply with regulatory requirements with timely patches.

Switching to TuxCare for Debian 10 support is straightforward. Connect to the TuxCare Debian 10 ELS repository using a simple script, and the system will start receiving security patches – which will continue automatically until June 2028. No reboot is required!


Final Thoughts


As Debian LTS bids farewell to Debian 10, organizations need to prepare for the security and compliance implications of Debian 10 EOL. Organizations can implement Extended Lifecycle Support (ELS) from TuxCare to strengthen security and stay compliant even after the EOL, buying years of time to safely migrate their systems.
