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 or telnet are enabled. Procedure: # grep ftp /etc/inetd.conf # grep telnet /etc/inetd.conf If either of these services are found, and are active, ask the SA if they encrypted. If they are not, this is a finding.

Fix Text

Edit /etc/inetd.conf and comment out or remove the ftp and telnet service lines. # vi /etc/inetd.conf Restart the inetd service. # refresh -s inetd
