cyberstrikeus 2.2.8 Ensure FTP Server is not installed (Automated)
Profile
- 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
Command Line
Run the following command to verify vsftpd is not installed:
# dpkg-query -s vsftpd &>/dev/null && echo "vsftpd is installed"
Nothing should be returned.
Expected Result
No output (empty result).
Remediation
Command Line
Run the following command to remove vsftpd:
# apt purge vsftpd
