Yes, SFTP (Secure File Transfer Protocol) is a secure way to transfer files over the internet.
When a user initiates an SFTP connection, the client and server negotiate a secure communication channel using SSH (Secure Shell) protocol. This creates an encrypted tunnel between the client and server, which ensures the confidentiality, integrity, and authenticity of the transferred data.
The SFTP client sends requests to the server to perform various functions such as listing directories, uploading or downloading files, and deleting files. These requests are encrypted and authenticated using SSH keys to ensure data privacy and secure file transfer.
SFTP uses port 22 for communication, making it less vulnerable to network attacks as it is restricted to a single port. Additionally, it supports features like public key authentication, file access control, and server auditing to ensure complete security of the data transfer process.
Overall, SFTP is a secure and reliable method for transferring files over the internet.
