Discussion

Anonymous FTP is a public data service which is only permitted in a server capacity when located on the DMZ network.

Check Content

Use the command ftp to connect the system's FTP service. Attempt to log into this host with a user name of anonymous and a password of guest (also try the password of guest@mail.com). If the logon is not successful, this check is not applicable. Ask the SA if the system is located on a DMZ network. If the system is not located on a DMZ network, this is a finding.

Move the system to a DMZ network.
