Protocol Deep Dive: FTP and Its Variants
Transferring files within a business is a critical capability that has become a basic operating necessity. This course explores both FTP active and passive modes, plus FTPS, SFTP, TFTP, all of which can operate using IPv4 and IPv6.
What you'll learn
Whether you are a business administrator or engineer of any flavor, you'll certainly require the ability to quickly, easily, and securely transfer files. In this course, Protocol Deep Dive: FTP and Its Variants, you will learn foundational knowledge required to deploy and operate a variety of file transfer services. First, you will learn about the classic FTP operating modes, active and passive, along with all the technical details surrounding their operation. Next, you will discover how to overcome security flaws with the original FTP specification by deploying FTP Secure via SSL (FTPS) or SSH-based FTP (SFTP). Finally, you will explore how to preserve your enterprise's file transfer capabilities during an IPv6 migration, which includes protocol messaging and security updates. When you're finished with this course, you will have the skills and knowledge needed to select the right file transfer method given a specific business goal or outcome. This includes expert-level troubleshooting, fault isolation, and detailed packet flow analysis.
