SV-63231r2_rule The system must not have the unnecessary ftp account.

Vulnerability discussion

Accounts that provide no operational purpose provide additional opportunities for system compromise. Unnecessary accounts include user accounts for individuals not requiring access to the system and application accounts for applications not installed on the system.

Check content

Check the system for the unnecessary "ftp" accounts. Procedure: # rpm -q krb5-workstation An ftp server is part of "krb5-workstation". If it is installed the "ftp" user is necessary and this is not a finding. # rpm -q vsftp If the "vsftp" ftp server is installed the "ftp" user is necessary and this is not a finding. # grep ^ftp /etc/passwd If this account exists and no ftp server is installed which requires it, this is a finding.

Fix text

Remove the "ftp" account from the /etc/passwd file before connecting a system to the network.

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.
