What are the best practices for securing the ELK stack?

To secure the ELK stack, you should implement user authentication, enable TLS encryption, and restrict access to sensitive data.

How can I implement user authentication?

You can use X-Pack for user authentication, which provides features like role-based access control and user management.

What about data encryption?

You should enable TLS for data in transit and consider encrypting data at rest using tools like Elasticsearch's built-in encryption.

Are there any specific firewall rules I should set?

Yes, restrict access to the ELK stack ports (like 9200 for Elasticsearch) to only trusted IP addresses.
