Title
Ubuntu 24.04 LTS must use SSH to protect the confidentiality and integrity of transmitted information. (Cat I impact)
Discussion
Without protection of the transmitted information, confidentiality and integrity may be compromised because unprotected communications can be intercepted and either read or altered. This requirement applies to both internal and external networks and all types of information system components from which information can be transmitted (e.g., servers, mobile devices, notebook computers, printers, copiers, scanners, and facsimile machines). Communication paths outside the physical protection of a controlled boundary are exposed to the possibility of interception and modification. Protecting the confidentiality and integrity of organizational information can be accomplished by physical means (e.g., employing physical distribution systems) or by logical means (e.g., employing cryptographic techniques). If physical means of protection are employed, then logical means (cryptography) do not have to be employed, and vice versa.

Check Content
Verify the "sshd.service" is enabled and active with the following commands: $ sudo systemctl is-enabled ssh enabled $ sudo systemctl is-active ssh active If "ssh.service" is not active or loaded, this is a finding.
Fix Text
Enable the "ssh" service to start automatically on reboot with the following command: $ sudo systemctl enable ssh.service ensure the "ssh" service is running $ sudo systemctl start ssh.service
