[[authentication-security-settings]]
|
|
==== Authentication security settings
|
|
|
|
You configure authentication settings in the `xpack.security.authc` namespace in `kibana.yml`.
|
|
|
|
For example:
|
|
|
|
[source,yaml]
|
|
----------------------------------------
|
|
xpack.security.authc:
|
|
providers:
|
|
basic.basic1: <1>
|
|
order: 0 <2>
|
|
...
|
|
|
|
saml.saml1: <3>
|
|
order: 1
|
|
...
|
|
|
|
saml.saml2: <4>
|
|
order: 2
|
|
...
|
|
|
|
pki.realm3:
|
|
order: 3
|
|
...
|
|
...
|
|
----------------------------------------
|
|
<1> Specifies the type of authentication provider (for example, `basic`, `token`, `saml`, `oidc`, `kerberos`, `pki`) and the provider name. This setting is mandatory.
|
|
<2> Specifies the order of the provider in the authentication chain and on the Login Selector UI. This setting is mandatory.
|
|
<3> Specifies the settings for the SAML authentication provider with a `saml1` name.
|
|
<4> Specifies the settings for the SAML authentication provider with a `saml2` name.
|
|
|
|
The valid settings in the `xpack.security.authc.providers` namespace vary depending on the authentication provider type. For more information, refer to <<kibana-authentication>>.

The link specified in `RelayState` should be a relative, URL-encoded {kib} URL.

You can configure the following settings in the `kibana.yml` file.
|
|
|
|
[cols="2*<"]
|
|
|===
|
|
| `xpack.security.cookieName`
|
|
| Sets the name of the cookie used for the session. The default value is `"sid"`.
|
|
|
|
|[[xpack-security-encryptionKey]] `xpack.security.encryptionKey`
|
|
| An arbitrary string of 32 characters or more that is used to encrypt session information. Do **not** expose this key to users of {kib}. By
|
|
default, a value is automatically generated in memory. If you use that default
|
|
behavior, all sessions are invalidated when {kib} restarts.
|
|
In addition, high-availability deployments of {kib} will behave unexpectedly
|
|
if this setting isn't the same for all instances of {kib}.
|
|
|
|
|[[xpack-security-secureCookies]] `xpack.security.secureCookies`
|
|
| Sets the `secure` flag of the session cookie. The default value is `false`. It
|
|
is automatically set to `true` if <<server-ssl-enabled, `server.ssl.enabled`>> is set to `true`. Set
|
|
this to `true` if SSL is configured outside of {kib} (for example, you are
|
|
routing requests through a load balancer or proxy).
|
|
|
|
| [[xpack-security-sameSiteCookies]] `xpack.security.sameSiteCookies` {ess-icon}
|
|
| Sets the `SameSite` attribute of the session cookie. This allows you to declare whether your cookie should be restricted to a first-party or same-site context.
|
|
Valid values are `Strict`, `Lax`, `None`.
|
|
This is *not set* by default, which modern browsers will treat as `Lax`. If you use Kibana embedded in an iframe in modern browsers, you might need to set it to `None`. Setting this value to `None` requires cookies to be sent over a secure connection by setting <<xpack-security-secureCookies, `xpack.security.secureCookies`>>: true`. Some old versions of IE11 do not support `SameSite: None`.
|
|
|
|
|[[xpack-session-idleTimeout]] `xpack.security.session.idleTimeout` {ess-icon}
|
|
| Ensures that user sessions will expire after a period of inactivity. This and <<xpack-session-lifespan,`xpack.security.session.lifespan`>> are both
|
|
highly recommended. You can also specify this setting for <<xpack-security-provider-session-idleTimeout, every provider separately>>. If this is _not_ set or set to `0`, then sessions will never expire due to inactivity. By default, this setting is not set.

[TIP]

[IMPORTANT]
|
|
============
|

In high-availability deployments, make sure you use the same encryption and decryption keys for all instances of {kib}. Although the keys can be specified in clear text in `kibana.yml`, it's recommended to store them securely in the <<secure-settings,{kib} Keystore>>.

`encryptionKey`
|
|
| An arbitrary string of at least 32 characters that is used to encrypt sensitive properties of saved objects before they're stored in {es}. If not set, {kib} will generate a random key on startup, but certain features won't be available until you set the encryption key explicitly.
