Title

RHEL 10 must, for all networked systems, have and implement Secure Shell (SSH) to protect the confidentiality and integrity of transmitted and received information.

Control

Verify RHEL 10 "sshd" is active with the following command: $ systemctl is-active sshd active If the "sshd" service is not active, this is a finding.

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 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.

Configure RHEL 10 to enable the sshd service by running the following command: $ systemctl enable --now sshd
