FTP is an insecure protocol that transfers files and credentials in clear text, and can be replaced by using SFTP. However, if FTP is permitted for use in the environment, it is important to ensure that the default "system" accounts are not permitted to transfer files via FTP, especially the root role. Consider also adding the names of other privileged or shared accounts that may exist on the system such as user "oracle" and the account which the web server process runs under.
The root role is required. Determine if the FTP server package is installed: # pkg list service/network/ftp If the output of this command is: pkg list: no packages matching 'service/network/ftp' installed no further action is required. If the FTP server is installed, determine if FTP access is restricted. # for user in `logins -s | awk '{ print $1 }'` \ aiuser noaccess nobody nobody4; do grep -w "${user}" /etc/ftpd/ftpusers >/dev/null 2>&1 if [ $? != 0 ]; then echo "User '${user}' not in /etc/ftpd/ftpusers." fi done If output is returned, this is a finding.

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.
