Linux RHEL-10-700010

Verify RHEL 10 is configured so that any SSH connection to the operating system displays the Standard Mandatory DoW Notice and Consent Banner before granting access to the system. Check for the location of the banner file currently being used with the following command: $ sudo /usr/sbin/sshd -dd 2>&1 | awk '/filename/ {print $4}' | tr -d '\r' | tr '\n' ' ' | xargs sudo grep -iH '^\s*banner' /etc/ssh/sshd_config.d/10-stig.conf:Banner /etc/issue If the line is commented out or the file is missing, this is a finding.

Configure RHEL 10 to display the Standard Mandatory DoW Notice and Consent Banner before granting access to the system via SSH. Edit a file in "/etc/ssh/sshd_config.d" to uncomment or add the banner keyword and configure it to point to a file that will contain the login banner (this file may be named differently or be in a different location if using a version of SSH that is provided by a third-party vendor). An example configuration line is: Banner /etc/issue
