Kibana, an open-source analytics and visualization platform, allows users to explore and visualize data from Elasticsearch clusters, which require robust security measures to prevent unauthorized access. One security method involves configuring Kibana to authenticate users via SAML (Security Assertion Mark-up Language) using an external Identity Provider like Google, facilitated through OAuth2. This setup necessitates configuring both Elasticsearch and Kibana to support SAML single-sign-on by establishing realms within the elasticsearch.yml configuration file and defining SAML metadata. The integration enables users to log into Kibana using their Google accounts, allowing them to analyze data through visual representations such as graphs and maps. The process involves specific configuration adjustments depending on the version of the Kibana instance and can accommodate multiple Kibana instances with unique SAML realms, providing flexibility in authentication methods across different identity providers.
