Configuring Kibana for SSL/TLS

If you are using Kibana with Elasticsearch, you need to configure Kibana to communicate with Elasticsearch over HTTPS.

Step 1: Update Kibana Configuration

Open the kibana.yml configuration file and add the following settings:

elasticsearch.hosts: ["https://localhost:9200"]
elasticsearch.ssl.certificateAuthorities: ["/path/to/elastic-stack-ca.crt"]
elasticsearch.username: "kibana_system"
elasticsearch.password: "password"

server.ssl.enabled: true
server.ssl.certificate: /path/to/kibana.crt
server.ssl.key: /path/to/kibana.key

Step 2: Restart Kibana

Restart Kibana to apply the new configuration:

bin/kibana
