SFTP provides all of the same functionality as FTP, but with the added security of SSH. SFTP is a completely different protocol from FTP, whereas FTPS is a secure version of FTP. SFTP is often confused with FTPS, but they are not the same thing. SFTP, or SSH File Transfer Protocol, is a secure version of FTP that uses SSH for encryption and authentication. To address this security issue, a secure version of FTP, called FTPS (FTP over SSL), was developed.
Passive mode is usually used when the client is behind a firewall or NAT device that blocks incoming connections.įTP does not provide any encryption for the data being transferred, which means that anyone with access to the network can intercept and read the data. In passive mode, the server opens a data connection and waits for the client to connect to it. In active mode, the client sends a command to the server to open a data connection, and the server sends data back over that connection. FTP is a client-server protocol, which means that one computer (the client) connects to another computer (the server) to transfer files.įTP can be used in two modes: active and passive. FTP was one of the first protocols developed for transferring files over a network and is still widely used today. FTP (File Transfer Protocol)įTP, or File Transfer Protocol, is a protocol used for transferring files between two computers. This can be useful for system administrators who need to manage multiple systems from a central location. In addition to remote login, SSH can also be used for remote command execution, which allows users to execute commands on a remote system without having to log in. Once the secure connection is established, the user can interact with the remote system as if they were physically sitting at the computer. The remote system then verifies the user's credentials and establishes a secure connection between the two systems.

When a user logs into a remote system using SSH, the user's username and password are encrypted and sent to the remote system. SSH uses encryption to protect the data being transmitted over the network. SSH was designed as a replacement for the less secure Telnet protocol, which transmitted data in plain text and was susceptible to eavesdropping. It is commonly used for remote login, remote command execution, and file transfer. SSH, or Secure Shell, is a protocol that provides secure, encrypted communication between two computers.
In this article, we will explore what these terms mean and the differences between them. Three such terms are SSH, FTP, and SFTP, which are all used for file transfer and remote access. In the world of information technology, there are many terms and acronyms that can be confusing and overwhelming, especially for those who are new to the field.
