Individual use cases may call for one before the rest, but in most situations, SFTP will be the best of the bunch. In a nutshell, each protocol is quite different from the next, but seeks to achieve the same goals of secure authentication and encryption. It has the distinct advantage of being faster than other options, but lacks the ability to list directories, remove files or make any changes to the remote directory structure.Īs a complete overhaul of the FTP protocol, it supports the same powerful set of features while utilizing SSH to handle secure authentication and data encryption. Strictly designed for file transfers within a secure shell, it is a safe, albeit limited protocol. Rather than change the method of authentication and file transfer, it’s enclosed FTP within a safe pathway that protects the internal data being transmitted. Since these naming conventions can be redundant and cause confusion, what are the primary differences between these 3?Īn extension of the same old FTP protocol, it encapsulates data within a secure SSL layer between the client and server. We also have FTPS (FTP over SSL) and SCP (Secure Copy Protocol) as viable alternatives. Comparing Secure ProtocolsĪlthough it’s one of the most robust options available, SFTP isn’t the only secure protocol on the block. This void in security is the very problem that spawned other protocols such as SFTP out of sheer necessity. Released back in 1985, this flawed design was more than sufficient for the early days of the internet, but presents a massive risk for networks in the modern digital age. Transmitting data in plain text over an insecure connection, malicious parties can easily sniff the packets and obtain a user’s credentials. The most notable drawback of FTP is the inherent lack of security it provides. It resembles the same core functionality as FTP in many regards, but the underlying architecture is an entirely different means of transport, reliant on a secure shell (SSH) to operate.
The Secure File Transfer Protocol ( SFTP) is a popular choice for file access, transfers and management on a remote server.
