# Hardened images / Extended lifetime support

Updating to the latest version of a base image can be a difficult task as it might required changes to your application. When updating to a newer base image is not a viable option, you can stay secure by using Aikido Extended Lifetime Support (i.e. hardened images).

Aikido maintains a registry of base images containing patched versions of libraries with reported **CRITICAL** or **HIGH** severity security issues. 

For example [CVE-2025-4373](https://security-tracker.debian.org/tracker/CVE-2025-4373) is fixed by Debian in Trixie and Sid but not in Bookworm. Our ELS `debian:bookworm` image contains a patched version of `glib2.0` that fixes this vulnerability. Using this image avoids breaking changes while maintaining a good security posture.

In Aikido, you can view which base images have supported ELS versions from the **AutoFix** > **Containers** page.
