HTTP Strict Transport Security (HSTS) is a security feature that forces clients to communicate with a web server only over HTTPS, even if they try to access it via HTTP. This helps protect against man-in-the-middle attacks and other security threats. Here’s how to set up HSTS with the Lighttpd web server:
- Enable HTTPS on your Lighttpd server: Before you can use HSTS, you need to have a working HTTPS configuration. You can learn more about setting up HTTPS with Lighttpd in their official documentation.
- Edit your Lighttpd configuration file: The configuration file for Lighttpd is typically located at
/etc/lighttpd/lighttpd.conf
. You can edit this file with a text editor, such asnano
. - Add the following line to your configuration file to enable HSTS:
$HTTP["scheme"] == "https" {
header.add("Strict-Transport-Security" => "max-age=31536000; includeSubdomains")
}
The max-age
directive sets the number of seconds that the HSTS policy will be in effect. The includeSubdomains
directive applies the HSTS policy to all subdomains as well.
- Save the changes: Save the changes to the configuration file and close the text editor.
- Restart the Lighttpd server: To apply the changes, you’ll need to restart the Lighttpd server. You can do this by running the following command:
sudo service lighttpd restart
- Test the HSTS implementation: You can test your HSTS implementation by visiting your website using a browser that supports HSTS and checking if the “Strict-Transport-Security” header is present in the response. You can also use an online HSTS checker to verify the implementation. (https://hummingbirddental.ca)
By following these steps, you should be able to set up HSTS with the Lighttpd web server.
