In this article, we will demonstrate how to configure a Secure FTP server (vsftpd) using SSL/TLS encryption. Traditional FTP services are not very secure and vulnerable because the credentials are transmitted in clear text, which is prone to crackdowns and many types of attacks like brute force. The majority of applications these days come with a security feature that can be used to set up a secure FTP server. Consider encrypting data between the Server and Client with FTPS (FTP Secure) in conjunction with SSL/TLS. SFTP (SSH File Transfer Protocol) is another way of securing data transmission. SFTP was developed as an extension of SSH, and it can also be used with other security protocols.
This tutorial will teach you how to setup an encrypted FTP server using SSL/TLS on Rocky Linux 8.5. You can use the same guide on RHEL, CentOS, Fedora, Ubuntu, Debian, and Ubuntu with a few minor modifications.
