SFTP stands for "Secure File Transfer Protocol." It is a network protocol used for secure file transfer between a client and a server. In contrast to traditional FTP (File Transfer Protocol), SFTP encrypts the entire data traffic, enhancing security.
Here are some key features of SFTP:
-
Encryption: SFTP encrypts both user authentication data and transmitted data, protecting them from unauthorized access.
-
Authentication: SFTP employs various authentication methods, including username/password, public-key authentication, and two-factor authentication.
-
Port: By default, SFTP uses port 22 for communication, though this can be customized in configurations.
-
Integrity: SFTP verifies the integrity of transmitted data, ensuring it is not manipulated during transfer.
-
File Management: SFTP allows for uploading and downloading files as well as managing files and directories on the server.
SFTP is commonly used by businesses and organizations to securely transfer sensitive information between different locations or users. It is particularly useful when secure file transfer is needed over insecure networks, such as the internet.
