What is Port 5601?

Port 5601 is the default port for Kibana, the visualization and exploration tool for Elasticsearch data and the frontend component of the Elastic Stack (ELK — Elasticsearch, Logstash, Kibana). Kibana provides a browser-based interface for searching, viewing, and interacting with data stored in Elasticsearch indices. It offers dashboards, visualizations, machine learning integration, alerting, and the ability to create custom applications through Kibana's Canvas and Lens features. Kibana is widely used for log analysis, application performance monitoring (APM), security analytics (SIEM), and infrastructure observability. When you need to explore and visualize log data, metrics, or security events, Kibana is typically the interface you interact with.

Common Uses

  • Log analysis and visualization dashboards
  • Application performance monitoring (APM)
  • Security information and event management (SIEM)
  • Infrastructure and business metrics visualization

Security Considerations

!

Kibana should not be exposed to the internet without authentication. Enable Elastic Security features including role-based access control. Use TLS for the connection between Kibana and Elasticsearch. Put Kibana behind a reverse proxy with authentication. Restrict access to authorized users and audit Kibana activity. Keep the Elastic Stack updated for security patches.
