SV-45876r1_rule Unencrypted FTP must not be used on the system.

Vulnerability discussion

: FTP is typically unencrypted and 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

Perform the following to determine if unencrypted FTP or Telnet are enabled: # chkconfig --list pure-ftpd # chkconfig --list telnet # chkconfig --list gssftp # chkconfig --list vsftpd If any of these services are found, ask the SA if these services are encrypted. If they are not, this is a finding.

Fix text

Disable the Telnet and FTP daemons. Procedure: # chkconfig pure-ftpd off # chkconfig telnet off # chkconfig gssftp off # chkconfig vsftpd off

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
