CloudLinux AlmaLinux OS 9 Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • AlmaLinux OS 9 must implement DOD-approved encryption ciphers to protect the confidentiality of SSH client connections.

    Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Remote access (e.g., RDP) is access to DOD nonpublic information systems by an auth...

  • AlmaLinux OS 9 IP tunnels must use FIPS 140-3 approved cryptographic algorithms.

    Overriding the system crypto policy makes the behavior of the Libreswan service violate expectations and makes the system configuration more fragmented.

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
