SFTP: Secure File Transfer Protocol – A Complete Guide

What is SFTP?


SFTP, or Secure File Transfer Protocol, is a network protocol that facilitates the secure transfer of files between systems over a reliable data stream. Unlike traditional FTP, which transmits data in plaintext, SFTP encrypts both commands and data, ensuring confidentiality and integrity during transmission. 


How Does SFTP Work?


SFTP operates over the SSH (Secure Shell) protocol, typically using port 22. When a connection is initiated, the client and server establish an encrypted session, allowing for secure file operations such as upload, download, deletion, and permission changes. This encryption safeguards against eavesdropping and man-in-the-middle attacks. 


Benefits of Using SFTP

  • Enhanced Security: SFTP encrypts both data and commands, providing a secure channel for file transfers.

  • Authentication Mechanisms: Supports various authentication methods, including password and public key authentication, ensuring only authorized access.

  • Firewall-Friendly: Utilizes a single port (22), simplifying firewall configurations and reducing potential vulnerabilities.

  • Data Integrity: Ensures that files are transferred completely and without corruption, maintaining data integrity.

  • Platform Independence: SFTP is platform-independent, allowing for seamless integration across different operating systems.


SFTP vs. FTP and FTPS


While FTP transmits data in plaintext, making it susceptible to interception, SFTP provides encryption for both commands and data, enhancing security. FTPS adds SSL/TLS encryption to FTP but requires multiple ports, complicating firewall configurations. In contrast, SFTP’s single-port design simplifies setup and is generally considered more secure.


Use Cases for SFTP

  • Healthcare: Transferring sensitive patient records while complying with HIPAA regulations.

  • Finance: Securely exchanging financial data and reports.

  • Legal: Sharing confidential legal documents between parties.

  • Manufacturing: Distributing proprietary designs and specifications securely.
