Title

Unencrypted FTP must not be used on the system. (Cat II impact)

Discussion

FTP is typically unencrypted and, therefore, presents confidentiality and integrity risks. FTP may be protected by encryption in certain cases, such as when used in a Kerberos environment. SFTP and FTPS are encrypted alternatives to FTP.

Check Content

Determine if unencrypted FTP is enabled. # cat /etc/inetd.conf | sed -e 's/^[ \t]*//' | tr '\011' ' ' | tr -s ' ' | grep -v "^#" | grep -c -i "^ftp" If the service is found (i.e., the command returns a non-zero value), and not commented, ask the SA if this service is encrypted. If not, this is a finding.

Fix Text

Edit /etc/inetd.conf and comment out or remove the ftp service. Refresh the inet daemon. inetd -c
