Verifying the SSL/TLS Configuration
To verify that SSL/TLS is correctly configured, you can use curl to make an HTTPS request to your Elasticsearch cluster.
Example Request
curl --cacert /path/to/elastic-stack-ca.crt -u elastic:password https://localhost:9200
If SSL/TLS is configured correctly, you should see a response from Elasticsearch similar to the following:
{
"name" : "node-1",
"cluster_name" : "my-cluster",
"cluster_uuid" : "abcd1234",
"version" : {
"number" : "7.10.0",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "abcdefg",
"build_date" : "2020-11-10T22:14:56.825533Z",
"build_snapshot" : false,
"lucene_version" : "8.7.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
Securing Elasticsearch with Advanced SSL/TLS Encryption Configuration
Securing Elasticsearch is crucial for protecting your data and ensuring secure communication within your Elasticsearch cluster and between clients. One of the most effective ways to achieve this is by configuring SSL/TLS encryption. This guide provides a detailed, beginner-friendly explanation of advanced SSL/TLS encryption configuration in Elasticsearch, complete with examples and outputs.
