6.9 Ensure FTP Server is not enabled (Not Scored)

Profile Applicability

• Level 1

Description

The File Transfer Protocol (FTP) provides networked computers with the ability to transfer files.

Rationale

FTP does not protect the confidentiality of data or authentication credentials. It is recommended sftp be used if file transfer is required. Unless there is a need to run the system as a FTP server (for example, to allow anonymous downloads), it is recommended that the package be deleted to reduce the potential attack surface.

Audit Procedure

Using Command Line

Ensure no start conditions listed for vsftpd:

initctl show-config vsftpd vsftpd

Expected Result

No start conditions should be listed for vsftpd.

Remediation

Using Command Line

Remove or comment out start lines in /etc/init/vsftpd.conf:

sed -i 's/^start/#start/' /etc/init/vsftpd.conf

Default Value

Not installed by default on Ubuntu 12.04 LTS Server.
