Description
Failure to display the DoD logon banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources. The SSH service must be configured to display the DoD logon warning banner through the SSH daemon configuration. The SSH daemon may also be used to provide SFTP service. The warning banner configuration for SSH will apply to SFTP.

Check Text ( C-39123r1_chk )
Verify the SSH daemon is configured for logon warning banners. # grep -i banner /etc/ssh/sshd_config \| grep -v '^#' # cat [banner file] Verify the Banner configuration line is present and the file it references contains a login warning banner. If the SSH daemon is not configured to display a logon warning banner, this is a finding.
