What is the difference between SSL and TLS in Elasticsearch?

What is the difference between SSL and TLS in Elasticsearch?

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are both protocols used to secure communications. TLS is the successor to SSL and is more secure. In Elasticsearch, TLS is recommended over SSL for encrypting data in transit.

Why should I use TLS instead of SSL?

Using TLS is important because it provides stronger encryption and better security features compared to SSL. SSL has known vulnerabilities that TLS addresses.

How do I enable TLS in my Elasticsearch setup?

To enable TLS in Elasticsearch, you need to configure the elasticsearch.yml file with the appropriate settings for your certificates and keys. You can also use the Elasticsearch Security features to manage user authentication.

Can I use both SSL and TLS together?

It's not recommended to use both SSL and TLS together. Instead, you should migrate to TLS for better security and performance.
