2.2.9 Ensure FTP Server is not enabled (Scored)
Profile Applicability
- Level 1 - Server
- Level 1 - Workstation
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
Run the following commands to verify no start conditions listed for vsftpd:
initctl show-config vsftpd
Verify the output shows vsftpd with no start conditions.
Expected Result
The vsftpd service should have no start conditions listed.
Remediation
Remove or comment out start lines in /etc/init/vsftpd.conf:
Note: Additional FTP servers also exist and should be audited.
Default Value
FTP server is not enabled by default.
