Backporting Definition

Definition

Backporting is applying specific updates or improvements introduced in a newer software version to an older version.

Its main objective is to increase security and expand functionality without compelling users to upgrade to the latest version.

Operating systems: Backporting is used to fix bugs and critical security patches in older operating systems. This happens even if the developer doesn’t support the older OS, as advanced exploits can compromise the developer’s reputation and impact sales of newer systems.
Web browsers: Some users may be unwilling to upgrade to new browser versions for various reasons. So, browser developers can backport essential security fixes to protect the browser’s market share and reputation.
Content management systems: Most websites run on older versions of CMS platforms like Drupal or WordPress. Thus, these CMS platforms backport the latest security fixes, ensuring that websites remain secure without upgrading their CMS platform (which might cause major changes in site functionality).

Detect the security vulnerability or bug in a software that requires an update or a patch.
Establish the patches, updates, and modifications needed to address the issue in later versions of similar software.
Revise the modification to ensure it works with the older code version.
Execute vigorous testing to ensure the proposed patch or update addresses the issue without compromising functionality and security.
Resolve any unintended outcomes that arise after implementing the patch.
Implement the backported patch.

Cost efficiency: Backporting only fixes the existing vulnerabilities, eliminating the need to redevelop or upgrade the entire system.
User satisfaction: Users can enjoy features of the latest software versions without disruptions from upgrading to a new version.
Security: Developers use backporting to fix security vulnerabilities and bugs on old systems using the security patches of new versions.
Sustainability: Backporting helps organizations maintain their systems without exposure to risks associated with major version upgrades.
