Assessment Title

Rule Text

Ubuntu 24.04 LTS must be a vendor-supported release.

Description

Discussion Text

An operating system release is considered "supported" if the vendor continues to provide security patches for the product. With an unsupported release, it will not be possible to resolve security issues discovered in the system software. The support status of the OS depends on its subscription status. End Of Life dates for Ubuntu 24.04 releases are as follows: Standard Support: April 2029 Extended Security Maintenance (ESM): April 2036 ESM is available via an Ubuntu Pro subscription.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

if [ -f /etc/lsb-release ]; then \
    grep -q "^DISTRIB_CODENAME=noble" /etc/lsb-release && echo "PASS" && exit 0 || echo "FAIL" && exit 1; \
else echo "PASS" && exit 0; fi
