It was developed over 40 years ago when the networks it was designed to run on were simpler – and safer. The original FTP protocol offers no security and transmits commands and data in an open, easily eavesdropped connection. Now that you understand the background of the different file transfer protocols, it’s helpful to discuss how they compare across a few criteria. Secure file transfer systems based on HTTPS overcome those two issues because nearly every system today has a web browser installed, and most users are familiar with the basics of using a web browser.
#SFTP FILE TRANSFER HOW TO#
One of the challenges with FTPS and SFTP is that a customer has to have a file transfer client installed that supports those protocols, and the customer has to be trained on how to use that client. Web browsers that use the HTTP protocol are ubiquitous today, and we can take advantage of that fact to offer a secure file transfer system based around HTTPS. We can leverage this same protocol to provide secure file transfer services to clients. We rely on HTTPS today to securely browse websites and safely make pu rchases online. It runs the HTTP protocol over a secure TLS connection. However, it can be safely secured by tunneling over TLS – in much the same way as FTPS makes FTP secure by tunneling it over TLS. Like its file transfer-focused cousin, FTP, the HTTP protocol is unencrypted and inherently unsafe as a secure file transfer protocol. The HTTP protocol has been around since the beginning of the Wo rld Wide Web, and is one of the foundational technologies underpinning the modern Internet. HyperText TransferProtocol (HTTP and HTTPS) Many of these capabilities have been added on to FTP over the years, but they aren’t all well standardized, or widely supported.

There are well-defined and supported SFTP commands for file and directory access, file integrity checking, and file transfer res ume capabilities. SFTP also has a more robust set of file transfer capabilities than FTP. SFTP is also considerably more firewall friendly than FTP because it only requires one port to establish a connection and carry out file operations. Unlike traditional FTP, SFTP runs over an SSH channel that provides security and integrity by default.

SFTP is a popular secure file transfer choice these days because of its robust security model and easier setup than FTP and FTPS. SSH2 File Transfer Protocol (SFTP)ĭespite the name, SFTP is a completely different protocol from traditional FTP. However, FTP and FTPS have been around for a long time, and ther e are still many devices and clients that only support FTP or FTPS. The requirement to set up forwarding for these ports is a security concern in many environments and can make troubleshooting problems difficult. This necessitates a large numb er of open ports for a file transfer system. Both FTP and FTPS require multiple ports (one port to issue commands and a separate port for each and every directory listing or file transfer) to perform file transfer operation. While FTPS is a significant security improvement over FTP, both protocols have limitations. FTPS was introduced to solve these problems by adding secure TLS encryption and authentication to the FTP protocol. This can allow eavesdropping on passwords and data, as well as connection hijacking by malicious servers. It also provides no way for a server to prove to a client that the server is who it claims to be. Unfortunately, FTP is by default an insecure protocol, transferring commands and data over an unencrypted connection. Overview of Secure File Transfer ProtocolsįTP is the original File Transfer Protocol and enjoys wide support from a variety o f clients and devices. We will go into each protocol in more detail in the following sections. Hosting a file transfer server that provides several secure file transfer protocols options hel ps ensure your users will be able to securely exchange data. For example, some networks may lock down SSH SFTP access, while leaving HTTPS available. Supporting the most common file transfer protocols provides your users with the ability to pick the option that works best for their environment. You w ant to avoid allowing plain, unencrypted FTP if security is a primary concern (and isn’t it always?) but SFTP, FTPS, and HTTPS are all considered secure file transfer protocols.

The short answer is to use a file transfer server that supports all three of the secure versions of those protocols.
#SFTP FILE TRANSFER INSTALL#
If you’re planning to install a secure file server to allow your clients or employees to securely share files, but you’re not sure which protocols to support, you have a lot of options:
