Vulnerability 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

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.
