In AWS Elastic Beanstalk, the server header is controlled by the underlying web server, which, in the case of a typical Node.js, Python, Ruby, or Go application, is usually Nginx. To remove the server header from Nginx responses in Elastic Beanstalk, you can use the
Here's how you can achieve it:
Create a new folder named
.ebextensionsin the root directory of your Elastic Beanstalk application if it doesn't already exist.
.ebextensionsfolder, create a new file (e.g.,
nginx.config) with the following content:yaml
files: "/etc/nginx/conf.d/my_custom_config.conf": mode: "000644" owner: root group: root content: | server_tokens off;
In the above configuration, we're creating a custom Nginx configuration file
/etc/nginx/conf.d/directory with the
server_tokensdirective set to
off. This directive will remove the server header from Nginx responses.
Deploy your application to Elastic Beanstalk with the new
After the deployment, Nginx will be configured with the
server_tokens off; directive, and the server header will be removed from the responses.
Please note that modifying the Nginx configuration can affect the behavior of your web server, so ensure that you understand the implications of removing the server header in your specific use case.
Additionally, remember to apply security best practices when exposing your applications to the internet. Removing the server header is one measure to reduce the information exposed, but there are other security considerations that should be addressed to enhance the security of your application.
