+#!/bin/bash
+
+# This script is designed to configure the SSH server on a Linux system according to Mozilla's security best practices.
+# Its main purpose is to enhance the security of SSH connections by enforcing modern encryption standards, disabling insecure protocols, and reducing potential attack vectors.
+# The script backs up the original SSH configuration file, applies a new set of secure settings, and then restarts the SSH service to apply the changes.
+# These settings include disabling password authentication, limiting access to strong ciphers and key exchange methods, and enhancing brute-force protection.
+# These recommendations are based on Mozilla's guidelines, which can be found here: https://infosec.mozilla.org/guidelines/openssh
+
+# Usage:
+# To run this script, save it as "secure_ssh.sh" and make it executable by running the command: `chmod +x secure_ssh.sh`.
+# After that, execute it with root privileges using: `sudo ./secure_ssh.sh`.
+# The script will automatically apply the recommended configuration changes and restart the SSH service.
