Audit logs

edit

Audit logging is a subscription feature that you can enable to keep track of security-related events, such as authorization success and failures. Logging these events enables you to monitor Kibana for suspicious activity and provides evidence in the event of an attack.

Use the Kibana audit logs in conjunction with Elasticsearch audit logging to get a holistic view of all security related events. Kibana defers to the Elasticsearch security model for authentication, data index authorization, and features that are driven by cluster-wide privileges. For more information on enabling audit logging in Elasticsearch, refer to Auditing security events.

Audit logs are disabled by default. To enable this functionality, you must set xpack.security.audit.enabled to true in kibana.yml.

You can optionally configure audit logs location, file/rolling file appenders and ignore filters using Audit logging settings.

Audit events

edit

Refer to the table of events that can be logged for auditing purposes.

Each event is broken down into category, type, action and outcome fields to make it easy to filter, query and aggregate the resulting logs. The trace.id field can be used to correlate multiple events that originate from the same request.

Refer to Audit schema for a table of fields that get logged with audit event.

To ensure that a record of every operation is persisted even in case of an unexpected error, asynchronous write operations are logged immediately after all authorization checks have passed, but before the response from Elasticsearch is received. Refer to the corresponding Elasticsearch logs for potential write errors.

Correlating audit events

edit

Audit events can be correlated in two ways:

Multiple Kibana audit events that resulted from the same request can be correlated together.
If Elasticsearch audit logging is enabled, Kibana audit events from one request can be correlated with backend calls that create Elasticsearch audit events.

The examples below are simplified, many fields have been omitted and values have been shortened for clarity.

Example 1: correlating multiple Kibana audit events

edit

When "thom" creates a new alerting rule, five audit events are written:

{"event":{"action":"http_request","category":["web"],"outcome":"unknown"},"http":{"request":{"method":"post"}},"url":{"domain":"localhost","path":"/api/alerting/rule","port":5601,"scheme":"https"},"user":{"name":"thom","roles":["superuser"]},"kibana":{"space_id":"default","session_id":"3dHCZRB..."},"@timestamp":"2022-01-25T13:05:34.449-05:00","message":"User is requesting [/api/alerting/rule] endpoint","trace":{"id":"e300e06..."}}
{"event":{"action":"space_get","category":["database"],"type":["access"],"outcome":"success"},"kibana":{"space_id":"default","session_id":"3dHCZRB...","saved_object":{"type":"space","id":"default"}},"user":{"name":"thom","roles":["superuser"]},"@timestamp":"2022-01-25T13:05:34.454-05:00","message":"User has accessed space [id=default]","trace":{"id":"e300e06..."}}
{"event":{"action":"connector_get","category":["database"],"type":["access"],"outcome":"success"},"kibana":{"space_id":"default","session_id":"3dHCZRB...","saved_object":{"type":"action","id":"5e3b1ae..."}},"user":{"name":"thom","roles":["superuser"]},"@timestamp":"2022-01-25T13:05:34.948-05:00","message":"User has accessed connector [id=5e3b1ae...]","trace":{"id":"e300e06..."}}
{"event":{"action":"connector_get","category":["database"],"type":["access"],"outcome":"success"},"kibana":{"space_id":"default","session_id":"3dHCZRB...","saved_object":{"type":"action","id":"5e3b1ae..."}},"user":{"name":"thom","roles":["superuser"]},"@timestamp":"2022-01-25T13:05:34.956-05:00","message":"User has accessed connector [id=5e3b1ae...]","trace":{"id":"e300e06..."}}
{"event":{"action":"rule_create","category":["database"],"type":["creation"],"outcome":"unknown"},"kibana":{"space_id":"default","session_id":"3dHCZRB...","saved_object":{"type":"alert","id":"64517c3..."}},"user":{"name":"thom","roles":["superuser"]},"@timestamp":"2022-01-25T13:05:34.956-05:00","message":"User is creating rule [id=64517c3...]","trace":{"id":"e300e06..."}}

All of these audit events can be correlated together by the same trace.id value "e300e06...". The first event is the HTTP API call, the next audit events are checks to validate the space and the connectors, and the last audit event is the actual rule creation.

Example 2: correlating a Kibana audit event with Elasticsearch audit events

edit

When "thom" logs in, a "user_login" Kibana audit event is written:

{"event":{"action":"user_login","category":["authentication"],"outcome":"success"},"kibana":{"session_id":"ab93zdA..."},"user":{"name":"thom","roles":["superuser"]},"@timestamp":"2022-01-25T09:40:39.267-05:00","message":"User [thom] has logged in using basic provider [name=basic]","trace":{"id":"818cbf3..."}}

The trace.id value "818cbf3..." in the Kibana audit event can be correlated with the opaque_id value in these six Elasticsearch audit events:

{"type":"audit", "timestamp":"2022-01-25T09:40:38,604-0500", "event.action":"access_granted", "user.name":"thom", "user.roles":["superuser"], "request.id":"YCx8wxs...", "action":"cluster:admin/xpack/security/user/authenticate", "request.name":"AuthenticateRequest", "opaque_id":"818cbf3..."}
{"type":"audit", "timestamp":"2022-01-25T09:40:38,613-0500", "event.action":"access_granted", "user.name":"kibana_system", "user.roles":["kibana_system"], "request.id":"Ksx73Ad...", "action":"indices:data/write/index", "request.name":"IndexRequest", "indices":[".kibana_security_session_1"], "opaque_id":"818cbf3..."}
{"type":"audit", "timestamp":"2022-01-25T09:40:38,613-0500", "event.action":"access_granted", "user.name":"kibana_system", "user.roles":["kibana_system"], "request.id":"Ksx73Ad...", "action":"indices:data/write/bulk", "request.name":"BulkRequest", "opaque_id":"818cbf3..."}
{"type":"audit", "timestamp":"2022-01-25T09:40:38,613-0500", "event.action":"access_granted", "user.name":"kibana_system", "user.roles":["kibana_system"], "request.id":"Ksx73Ad...", "action":"indices:data/write/bulk[s]", "request.name":"BulkShardRequest", "indices":[".kibana_security_session_1"], "opaque_id":"818cbf3..."}
{"type":"audit", "timestamp":"2022-01-25T09:40:38,613-0500", "event.action":"access_granted", "user.name":"kibana_system", "user.roles":["kibana_system"], "request.id":"Ksx73Ad...", "action":"indices:data/write/index:op_type/create", "request.name":"BulkItemRequest", "indices":[".kibana_security_session_1"], "opaque_id":"818cbf3..."}
{"type":"audit", "timestamp":"2022-01-25T09:40:38,613-0500", "event.action":"access_granted", "user.name":"kibana_system", "user.roles":["kibana_system"], "request.id":"Ksx73Ad...", "action":"indices:data/write/bulk[s][p]", "request.name":"BulkShardRequest", "indices":[".kibana_security_session_1"], "opaque_id":"818cbf3..."}

The Elasticsearch audit events show that "thom" authenticated, then subsequently "kibana_system" created a session for that user.
