=== Security Settings in Elasticsearch
|
|
++++
|
|
<titleabbrev>Security Settings</titleabbrev>
|
|
++++
|
|
|
|
By default, {security} is disabled when you have a basic or trial license. To
|
|
enable {security}, use the `xpack.security.enabled` setting.
|
|
|
|
You configure `xpack.security` settings to
|
|
<<anonymous-access-settings, enable anonymous access>>
|
|
and perform message authentication,
|
|
<<field-document-security-settings, set up document and field level security>>,
|
|
<<realm-settings, configure realms>>,
|
|
<<ssl-tls-settings, encrypt communications with SSL>>, and
|
|
<<auditing-settings, audit security events>>.
|
|
|
|
All of these settings can be added to the `elasticsearch.yml` configuration file,
|
|
with the exception of the secure settings, which you add to the {es} keystore.
|
|
For more information about creating and updating the {es} keystore, see
|
|
<<secure-settings>>.

|
|
[[general-security-settings]]
|
|
==== General Security Settings
|
|
`xpack.security.enabled`::
|
|
Set to `true` to enable {security} on the node. +
|
|
+
|
|
If set to `false`, which is the default value for basic and trial licenses,
|
|
{security} is disabled. It also affects all {kib} instances that connect to this
|
|
{es} instance; you do not need to disable {security} in those `kibana.yml` files.
|
|
For more information about disabling {security} in specific {kib} instances, see {kibana-ref}/security-settings-kb.html[{kib} Security Settings].
|
|
|
|
`xpack.security.hide_settings`::
|
|
A comma-separated list of settings that are omitted from the results of the
|
|
<<cluster-nodes-info,cluster nodes info API>>. You can use wildcards to include
|
|
multiple settings in the list. For example, the following value hides all the
|
|
settings for the ad1 realm: `xpack.security.authc.realms.ad1.*`. The API already
|
|
omits all `ssl` settings, `bind_dn`, and `bind_password` due to the
|
|
sensitive nature of the information.
|
|
|
|
[float]
|
|
[[password-security-settings]]
|
|
==== Default Password Security Settings
|
|
`xpack.security.authc.accept_default_password`::
|
|
In `elasticsearch.yml`, set this to `false` to disable support for the default "changeme" password.
|
|
|
|
[float]
|
|
[[anonymous-access-settings]]
|
|
==== Anonymous Access Settings
|
|
You can configure the following anonymous access settings in
|
|
`elasticsearch.yml`. For more information, see {xpack-ref}/anonymous-access.html[
|
|
Enabling Anonymous Access].
|
|
|
|
`xpack.security.authc.anonymous.username`::
|
|
The username (principal) of the anonymous user. Defaults to `_es_anonymous_user`.
|
|
|
|
`xpack.security.authc.anonymous.roles`::
|
|
The roles to associate with the anonymous user. Required.
|
|
|
|
`xpack.security.authc.anonymous.authz_exception`::
|
|
When `true`, an HTTP 403 response is returned if the anonymous user
|
|
does not have the appropriate permissions for the requested action. The
|
|
user is not prompted to provide credentials to access the requested
|
|
resource. When set to `false`, a HTTP 401 is returned and the user
|
|
can provide credentials with the appropriate permissions to gain
|
|
access. Defaults to `true`.
|
|
|
|
[float]
|
|
[[field-document-security-settings]]
|
|
==== Document and Field Level Security Settings
|
|
|
|
You can set the following document and field level security
|
|
settings in `elasticsearch.yml`. For more information, see
|
|
{xpack-ref}/field-and-document-access-control.html[Setting Up Document and Field
|
|
Level Security].
|
|
|
|
`xpack.security.dls_fls.enabled`::
|
|
Set to `false` to prevent document and field level security
|
|
from being configured. Defaults to `true`.
|
|
|
|
[float]
|
|
[[token-service-settings]]
|
|
==== Token Service Settings
|
|
|
|
You can set the following token service settings in
|
|
`elasticsearch.yml`.
|
|
|
|
`xpack.security.authc.token.enabled`::
|
|
Set to `false` to disable the built-in token service. Defaults to `true` unless
|
|
`xpack.security.http.ssl.enabled` is `false` and `http.enabled` is `true`.
|
|
This prevents sniffing the token from a connection over plain http.
|
|
|
|
`xpack.security.authc.token.timeout`::
|
|
The length of time that a token is valid for. By default this value is `20m` or
|
|
20 minutes. The maximum value is 1 hour.
|
|
|
|
[float]
|
|
[[realm-settings]]
|

==== Realm Settings
|

You configure realm settings in the `xpack.security.authc.realms`
|
|
namespace in `elasticsearch.yml`. For example:
|
|
|
|

===== Default TLS/SSL Key and Trusted Certificate Settings
|
|
|
|
The following settings are used to specify a private key, certificate, and the
|
|
trusted certificates that should be used when communicating over an SSL/TLS connection.
|
|
If none of the settings below are specified, this will default to the <<ssl-tls-settings, {xpack}
|
|
defaults>>. If no trusted certificates are configured, the default certificates that are trusted by the JVM will be
|
|
trusted along with the certificate(s) from the <<tls-ssl-key-settings, key settings>>. The key and certificate must be in place
|
|
for connections that require client authentication or when acting as a SSL enabled server.

|
|
that will be presented to clients when they connect.
|
|
|
|
`xpack.ssl.certificate_authorities`::
|

|
===== Java Keystore Files
|
|

When using Java keystore files (JKS), which contain the private key, certificate
|
|

|
|
===== PKCS#12 Files
|
|
|
|
When using PKCS#12 container files (`.p12` or `.pfx`), which contain the
|
|
private key, certificate, and certificates that should be trusted, use
|
|
the following settings:
|
|
|
|
`xpack.ssl.keystore.path`::
|
|
Path to the PKCS#12 file that holds the private key and certificate.
|
|
|
|
`xpack.ssl.keystore.type`::
|
|
Set this to `PKCS12`.
|
|
|
|
`xpack.ssl.keystore.password`::
|
|
Password to the PKCS#12 file.
|
|
|
|
`xpack.ssl.keystore.secure_password` (<<secure-settings,Secure>>)::

|
Password to the PKCS#12 file.
|
|
|
|
`xpack.ssl.keystore.key_password`::
|
|
Password for the private key in the PKCS12 file.

|
Defaults to the same value as `xpack.ssl.keystore.password`.
|

|
|
|
|
`xpack.ssl.truststore.type`::
|
|
Set this to `PKCS12`.
|
|
|
|
`xpack.ssl.truststore.password`::
|
|
Password to the truststore.

===== Transport Profile TLS/SSL Settings
|
|
The same settings that are available for the <<transport-tls-ssl-settings, default transport>>
|
|
are also available for each transport profile. By default, the settings for a
|
|
transport profile will be the same as the default transport unless they
|
|
are specified.
|
|
|
|
As an example, lets look at the key setting. For the default transport
|
|
this is `xpack.security.transport.ssl.key`. In order to use this setting in a
|
|
transport profile, use the prefix `transport.profiles.$PROFILE.xpack.security.` and
|
|
append the portion of the setting after `xpack.security.transport.`. For the key
|
|
setting, this would be `transport.profiles.$PROFILE.xpack.security.ssl.key`.
