Maintaining a website requires a secure way to move files between your local machine and the live web server. The two primary methods used by administrators are FTP (File Transfer Protocol) and SSH (Secure Shell).
Plain FTP sends data, including your passwords, in unencrypted text, making it highly vulnerable to interception. Security-conscious businesses use SFTP or SSH instead. SSH creates a completely encrypted tunnel between your computer and the server. This not only allows you to upload files securely but also gives you a secure command-line interface to run backend cleanup scripts, manage system updates, and monitor server health in real-time. Protecting these entry points is the first line of defense in modern cybersecurity.
