Question
Your manager asks you to set up a secure network connection at a remote site to move over some backups.
Which protocol would you use?
Solution
To set up a secure network connection for transferring backups to a remote site, the recommended protocol would be Secure File Transfer Protocol (SFTP) or SSH File Transfer Protocol.
Explanation of the Protocol:
-
Security: SFTP operates over the SSH (Secure Shell) protocol, providing a secure channel for data transfer. It encrypts both the command and data channels, ensuring that the backups are transmitted securely without the risk of interception.
-
Authentication: SFTP supports various authentication methods, including password-based and key-based authentication, enhancing security.
-
Functionality: It allows not only file transfers but also file management functionalities, such as directory listing and file permission changes.
-
Firewall Friendly: SFTP operates over a single port (usually port 22), making it more firewall-friendly compared to other protocols that require multiple ports.
In summary, SFTP is an excellent choice for securely transferring backups to a remote location, thanks to its robust security features, ease of use, and compatibility with various firewall configurations.
