Technical Details

what runs on :5601

Kibana commonly listens on TCP 5601 and serves a browser-based web application over HTTP by default; TLS can be enabled in Kibana or provided by a reverse proxy. The interface and its API use HTTP requests and responses, including JSON, to interact with Elasticsearch. UDP 5601 is not a normal Kibana listener. This common use differs from IANA's assignment of the port to Enterprise Security Agent, registered to Kimberly Gibbs.

security overview

An internet-accessible Kibana instance can expose dashboards, searches, and potentially sensitive Elasticsearch data; available access depends on the Elastic version and its authentication and authorization configuration. Do not expose it directly to the public internet unless necessary: restrict access with network controls and authentication, and use HTTPS. Older or misconfigured deployments may lack adequate access controls.
