All of these settings can be added to the `elasticsearch.yml` configuration

file. For more information, see

[[general-audit-settings]]
|
|
==== General Auditing Settings
|
|
|
|
`xpack.security.audit.enabled`::
|
|
Set to `true` to enable auditing on the node. The default value is `false`.
|
|
|
|
`xpack.security.audit.outputs`::
|
|
Specifies where audit logs are output. For example: `[ index, logfile ]`. The
|
|
default value is `logfile`, which puts the auditing events in a dedicated
|
|
`<clustername>_access.log` file on the node. You can also specify `index`, which
|
|
puts the auditing events in an {es} index that is prefixed with
|
|
`.security_audit_log`. The index can reside on the same cluster or a separate
|
|
cluster.
|
|
+
|
|
--
|
|
TIP: If the index is unavailable, it is possible for auditing events to
|
|
be lost. The `index` output type should therefore be used in conjunction with
|
|
the `logfile` output type and the latter should be the official record of events.

|
==== Audited Event Settings
|
|
|
|
The events and some other information about what gets logged can be
|
|
controlled by using the following settings:
|
|
|
|
`xpack.security.audit.logfile.events.include`::
|
|
Specifies which events to include in the auditing output. The default value is:
|
|
`access_denied, access_granted, anonymous_access_denied, authentication_failed, connection_denied, tampered_request, run_as_denied, run_as_granted`.
|
|
|
|
`xpack.security.audit.logfile.events.exclude`::
|
|
Excludes the specified events from the output. By default, no events are
|
|
excluded.
|
|
|
|
`xpack.security.audit.logfile.events.emit_request_body`::
|
|
Specifies whether to include the request body from REST requests on certain
|
|
event types such as `authentication_failed`. The default value is `false`.
|
|
+
|
|
--
|
|
IMPORTANT: No filtering is performed when auditing, so sensitive data may be
|
|
audited in plain text when including the request body in audit events.

[[node-audit-settings]]
|
|
==== Local Node Info Settings
|
|
|
|
`xpack.security.audit.logfile.prefix.emit_node_name`::
|
|
Specifies whether to include the node's name in the local node info. The
|
|
default value is `true`.
|
|
|
|
`xpack.security.audit.logfile.prefix.emit_node_host_address`::
|
|
Specifies whether to include the node's IP address in the local node info. The
|
|
default value is `false`.
|
|
|
|
`xpack.security.audit.logfile.prefix.emit_node_host_name`::
|
|
Specifies whether to include the node's host name in the local node info. The
|
|
default value is `false`.
|
|
|
|
[[index-audit-settings]]
|
|
==== Audit Log Indexing Configuration Settings
|
|
|
|
`xpack.security.audit.index.bulk_size`::
|
|
Controls how many audit events are batched into a single write. The default
|
|
value is `1000`.
|
|
|
|
`xpack.security.audit.index.flush_interval`::
|
|
Controls how often buffered events are flushed to the index. The default value
|
|
is `1s`.
|
|
|
|
`xpack.security.audit.index.rollover`::
|
|
Controls how often to roll over to a new index: `hourly`, `daily`, `weekly`, or
|
|
`monthly`. The default value is `daily`.
|
|
|
|
`xpack.security.audit.index.events.include`::
|
|
Specifies the audit events to be indexed. The default value is
|
|
`anonymous_access_denied, authentication_failed, realm_authentication_failed, access_granted, access_denied, tampered_request, connection_granted, connection_denied, run_as_granted, run_as_denied`.
|
|
See {xpack-ref}/auditing.html#audit-event-types[Audit Entry Types] for the
|
|
complete list.
|
|
|
|
`xpack.security.audit.index.events.exclude`::
|
|
Excludes the specified auditing events from indexing. By default, no events are
|
|
excluded.
|
|
|
|
`xpack.security.audit.index.events.emit_request_body`::
|
|
Specifies whether to include the request body from REST requests on certain
|
|
event types such as `authentication_failed`. The default value is `false`.
|
|
|
|
`xpack.security.audit.index.settings`::
|
|
Specifies settings for the indices that the events are stored in. For example,
|
|
the following configuration sets the number of shards and replicas to 1 for the
|
|
audit indices:
|
|
+
|

xpack.security.audit.index.settings:

number_of_shards: 1

number_of_replicas: 1

[[remote-audit-settings]]
|
|
==== Remote Audit Log Indexing Configuration Settings
|
|
|
|
To index audit events to a remote {es} cluster, you configure the following
|
|
`xpack.security.audit.index.client` settings:
|
|
|
|
`xpack.security.audit.index.client.hosts`::
|
|
Specifies a comma-separated list of `host:port` pairs. These hosts should be
|
|
nodes in the remote cluster. If you are using default values for the
|
|
<<common-network-settings,`transport.tcp.port`>> setting, you can omit the
|
|
`port` value. Otherwise, it must match the `transport.tcp.port` setting.
|
|
|
|
`xpack.security.audit.index.client.cluster.name`::
|
|
Specifies the name of the remote cluster.
|
|
|
|
`xpack.security.audit.index.client.xpack.security.user`::
|
|
Specifies the `username:password` pair that is used to authenticate with the
|
|
remote cluster.
|
|
|
|
You can pass additional settings to the remote client by specifying them in the
|
|
`xpack.security.audit.index.client` namespace. For example, to allow the remote
|
|
client to discover all of the nodes in the remote cluster you can specify the
|
|
`client.transport.sniff` setting:
|
|
|
|
[source,yaml]
|
|
----------------------------
|
|
xpack.security.audit.index.client.transport.sniff: true
|
|
----------------------------
