So far Ubuntu 22.04 has not been accepted for compliance hardening.

we are trying the ubuntu 22.04 but we got a mail from Canonical | Ubuntu <email address hidden> saying that CIS hardening now available for Ubuntu 22.04 LTS!

Canonical has published the CIS benchmark hardening profile for the Ubuntu Security Guide on Jammy Jellyfish!

This release provides automated remediation and auditing at scale for Ubuntu Pro customers, bringing 22.04 LTS systems in line with the industry standard CIS hardening benchmarks. The USG tool is available for previous Ubuntu releases, and now extends to the latest Ubuntu LTS.

• What the CIS benchmarks are all about
• Ubuntu Security Guide tooling provides to Pro users,
• [Demo] How easy it is to install and run USG to create a hardened environment.
• And of course, we will include some tips and tricks to make the process easier!

Best regards,
Canonical Team
