The first version of FTP was drafted in the 1970s for scientific and research use within the U.S. See More: What Is Network Traffic Analysis? Definition, Importance, Implementation, and Best Practices What Is File Transfer Protocol Secure (FTPS)?įile transfer protocol secure, or FTPS for short, adds a layer of security to the legacy network communication protocol and file transfer protocol (FTP), through additional support for the Transport Layer Security (TLS).įTPS Uses Two Links and the Encryption Tunnel or Layer is Separate, nor InherentįTP is one of the oldest network communication protocols available today, and it predates the global internet.

It is a relatively modern network protocol and builds on the highly flexible SSH communication mechanism.

Supports server-to-server file transfers with control over file permissions.

Suitable for Linux and Unix-based network servers.

Communication is binary without inherent human readability.

Needs only one connection to send and receive data.

Some of the critical features of SFTP include:

Several stakeholders have worked on SFTP development between the 1990s and the late 2010s, but the later work by IETF formed the foundation of SFTP as we know it today. The IETF worked on SFTP for several years and came out with the updated SFTP version 4 in 2013. However, FTP was simple, convenient, and affordable without any guardrails for security. Before the development of SFTP, file transfer protocol (FTP) was the most commonly used method for sending and receiving files via remote connections. The Internet Engineering Task Force (IETF) that came up with SSH-2 also wanted to extend its functionalities to file transfers. SFTP is an improvement upon SSH version 2.

In 2006, SSH version 2 replaced SSH 1 as the global standard in secure connectivity, as it promised greater safety and more features. SSH is a vital pillar of the global internet and is operated through both open source and proprietary software. It uses a public key cryptography technique to authenticate remote connections and drive secure user access to data. SSH version 1 was developed in the 1990s to overcome security gaps in network infrastructures. SFTP Uses a Single Connection and is Inherently Encrypted

It also includes access, and management over a reliable data stream, building on version 2.0 of the secure shell protocol (SSH). Secure shell file transfer protocol, also known as SSH FTP or SFTP, is a network protocol that enables file secure file transfer using two distinct communication mechanisms.
