GEN000410 - The FTPS/FTP service on the system must be configured with the DoD login banner - '/etc/herald contains banner'

Information

Failure to display the login banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources. NOTE: SFTP and FTPS are encrypted alternatives to FTP and should be used in place of FTP. SFTP is implemented by the SSH service and uses its banner configuration.

Solution

Configure the system to display one of the DoD login banners (based on the character limitations imposed by the system) prior to any FTP login attempt.
Add a banner file to the system with the DoD login banner.
#vi /etc/herald
<Add DoD banner to file>
#chmod 644 /etc/herald
#chown root:system /etc/herald
Add a herald line to the /etc/ftpaccess.ctl file.
#vi /etc/ftpaccess.ctl
<add/update line in /etc/ftpaccess.ctl> herald: /etc/herald
#chown root:system /etc/ftpaccess.ctl
#chmod 640 /etc/ftpaccess.ctl
