How Do I Secure My Raspberry Pi Web Server?

Setting up a Raspberry Pi web server is an exciting project, but it’s essential to prioritize security to protect your data and ensure the server remains secure from unauthorized access. In this tutorial, we will guide you through the steps to secure your Raspberry Pi web server.

1. Change the Default Password

The first and most crucial step is to change the default password for your Raspberry Pi. Leaving the default password unchanged makes it vulnerable to unauthorized access. To change the password:

  1. Open a terminal on your Raspberry Pi or connect remotely using SSH.
  2. Typepasswd” and press Enter.
  3. Enter your current password, followed by a new, strong password. Remember to choose a combination of uppercase and lowercase letters, numbers, and special characters.
  4. Confirm your new password.
  5. You have successfully changed the default password for your Raspberry Pi!

2. Update Your Raspberry Pi

To keep your Raspberry Pi secure, it’s important to regularly update the operating system and software packages:

  1. Open a terminal.
  2. Typesudo apt update && sudo apt upgrade -y” and press Enter.
  3. This command will update all installed packages on your Raspberry Pi.

3. Enable Firewall Protection

A firewall acts as a barrier between your web server and potential threats from external networks. To enable firewall protection on your Raspberry Pi:

  1. Open a terminal.
  2. Typesudo ufw enable” and press Enter.
  3. The firewall is now enabled and will start automatically on boot.

4. Disable Root SSH Access

By default, the root user is enabled on the Raspberry Pi, allowing potential attackers to Target it directly. Disabling root SSH access adds an extra layer of security:

  1. Open a terminal.
  2. Typesudo nano /etc/ssh/sshd_config” and press Enter.
  3. In the file editor, locate the line that says “#PermitRootLogin yes“. Remove the “#” at the beginning of the line.
  4. Change “yes” to “no“. The line should now read “PermitRootLogin no“.
  5. Save the changes by pressing Ctrl + X, followed by Y, and then Enter.
  6. Typesudo service ssh restart” to restart the SSH service.
  7. You have successfully disabled root SSH access.

5. Secure Web Applications

If you are running web applications on your Raspberry Pi, it’s crucial to secure them too:

  • Create separate user accounts for each application to limit their privileges.

    • To create a user account, open a terminal and type “sudo adduser <username>“.

  • Regularly update your web applications to ensure they are running the latest secure versions.

    • Check the official documentation of each application for update instructions.

  • Implement secure HTTPS connections for your web applications using SSL/TLS certificates.

    • You can obtain free SSL certificates from Let’s Encrypt or use commercial providers.


In this tutorial, we covered essential steps to secure your Raspberry Pi web server. By changing the default password, updating your Raspberry Pi, enabling firewall protection, disabling root SSH access, and securing web applications, you have significantly enhanced the security of your Raspberry Pi web server. Remember to stay vigilant and keep up with security best practices to protect your server from potential threats.

Happy and secure Raspberry Pi web serving!
