Security settings in Kibanaedit

You do not need to configure any additional settings to use the security features in Kibana. They are enabled by default.

In high-availability deployments, make sure you use the same security settings for all instances of Kibana. Also consider storing sensitive security settings, such as encryption and decryption keys, securely in the Kibana Keystore, instead of keeping them in clear text in the kibana.yml file.

Authentication security settingsedit

You configure authentication settings in the xpack.security.authc namespace in kibana.yml.

For example:

xpack.security.authc:
    providers:
      basic.basic1: 
          order: 0 
          ...

      saml.saml1: 
          order: 1
          ...

      saml.saml2: 
          order: 2
          ...

      pki.realm3:
          order: 3
          ...
    ...

Specifies the type of authentication provider (for example, basic, token, saml, oidc, kerberos, pki) and the provider name. This setting is mandatory.

Specifies the order of the provider in the authentication chain and on the Login Selector UI. This setting is mandatory.

Specifies the settings for the SAML authentication provider with a saml1 name.

Specifies the settings for the SAML authentication provider with a saml2 name.

Valid settings for all authentication providersedit

The valid settings in the xpack.security.authc.providers namespace vary depending on the authentication provider type. For more information, refer to Authentication.

xpack.security.authc.providers.<provider-type>.<provider-name>.enabled logo cloud
Determines if the authentication provider should be enabled. By default, Kibana enables the provider as soon as you configure any of its properties.
xpack.security.authc.providers.<provider-type>.<provider-name>.order logo cloud
Order of the provider in the authentication chain and on the Login Selector UI.
xpack.security.authc.providers.<provider-type>.<provider-name>.description logo cloud
Custom description of the provider entry displayed on the Login Selector UI.
xpack.security.authc.providers.<provider-type>.<provider-name>.hint logo cloud
Custom hint for the provider entry displayed on the Login Selector UI.
xpack.security.authc.providers.<provider-type>.<provider-name>.icon logo cloud
Custom icon for the provider entry displayed on the Login Selector UI.
xpack.security.authc.providers.<provider-type>.<provider-name>.showInSelector logo cloud

Flag that indicates if the provider should have an entry on the Login Selector UI. Setting this to false doesn’t remove the provider from the authentication chain.

You are unable to set this setting to false for basic and token authentication providers.

xpack.security.authc.providers.<provider-type>.<provider-name>.accessAgreement.message logo cloud
Access agreement text in Markdown format. For more information, refer to Access agreement.
xpack.security.authc.providers.<provider-type>.<provider-name>.session.idleTimeout logo cloud

Ensures that user sessions will expire after a period of inactivity. Setting this to 0 will prevent sessions from expiring because of inactivity. By default, this setting is equal to xpack.security.session.idleTimeout.

Use a string of <count>[ms\|s\|m\|h\|d\|w\|M\|Y] (e.g. 20m, 24h, 7d, 1w).

xpack.security.authc.providers.<provider-type>.<provider-name>.session.lifespan logo cloud

Ensures that user sessions will expire after the defined time period. This behavior is also known as an "absolute timeout". If this is set to 0, user sessions could stay active indefinitely. By default, this setting is equal to xpack.security.session.lifespan.

Use a string of <count>[ms\|s\|m\|h\|d\|w\|M\|Y] (e.g. 20m, 24h, 7d, 1w).

SAML authentication provider settingsedit

In addition to the settings that are valid for all providers, you can specify the following settings:

xpack.security.authc.providers.saml.<provider-name>.realm logo cloud
SAML realm in Elasticsearch that provider should use.
xpack.security.authc.providers.saml.<provider-name>.useRelayStateDeepLink logo cloud
Determines if the provider should treat the RelayState parameter as a deep link in Kibana during Identity Provider initiated log in. By default, this setting is set to false. The link specified in RelayState should be a relative, URL-encoded Kibana URL. For example, the /app/dashboards#/list link in RelayState parameter would look like this: RelayState=%2Fapp%2Fdashboards%23%2Flist.

OpenID Connect authentication provider settingsedit

In addition to the settings that are valid for all providers, you can specify the following settings:

xpack.security.authc.providers.oidc.<provider-name>.realm logo cloud
OpenID Connect realm in Elasticsearch that the provider should use.

Anonymous authentication provider settingsedit

In addition to the settings that are valid for all providers, you can specify the following settings:

You can configure only one anonymous provider per Kibana instance.

xpack.security.authc.providers.anonymous.<provider-name>.credentials logo cloud

Credentials that Kibana should use internally to authenticate anonymous requests to Elasticsearch.

For example:

xpack.security.authc.providers.anonymous.anonymous1:
  credentials:
    username: "anonymous_service_account"
    password: "anonymous_service_account_password"

For more information, refer to Anonymous authentication.

HTTP authentication settingsedit

There is a very limited set of cases when you’d want to change these settings. For more information, refer to HTTP authentication.

xpack.security.authc.http.enabled
Determines if HTTP authentication should be enabled. By default, this setting is set to true.
xpack.security.authc.http.autoSchemesEnabled
Determines if HTTP authentication schemes used by the enabled authentication providers should be automatically supported during HTTP authentication. By default, this setting is set to true.
xpack.security.authc.http.schemes[]
List of HTTP authentication schemes that Kibana HTTP authentication should support. By default, this setting is set to ['apikey', 'bearer'] to support HTTP authentication with the ApiKey and Bearer schemes.

Login user interface settingsedit

You can configure the following settings in the kibana.yml file.

xpack.security.loginAssistanceMessage logo cloud
Adds a message to the login UI. Useful for displaying information about maintenance windows, links to corporate sign up pages, and so on.
xpack.security.loginHelp logo cloud
Adds a message accessible at the login UI with additional help information for the login process.
xpack.security.authc.selector.enabled logo cloud
Determines if the login selector UI should be enabled. By default, this setting is set to true if more than one authentication provider is configured.

Configure a default access agreementedit

You can configure the following settings in the kibana.yml file.

xpack.security.accessAgreement.message logo cloud
This setting specifies the access agreement text in Markdown format that will be used as the default access agreement for all providers that do not specify a value for xpack.security.authc.providers.<provider-type>.<provider-name>.accessAgreement.message. For more information, refer to Access agreement.

Session and cookie security settingsedit

You can configure the following settings in the kibana.yml file.

xpack.security.cookieName
Sets the name of the cookie used for the session. The default value is "sid".
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 Kibana. By default, a value is automatically generated in memory. If you use that default behavior, all sessions are invalidated when Kibana restarts. In addition, high-availability deployments of Kibana will behave unexpectedly if this setting isn’t the same for all instances of Kibana.
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 is set to true. Set this to true if SSL is configured outside of Kibana (for example, you are routing requests through a load balancer or proxy).
xpack.security.sameSiteCookies logo cloud
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: true.
xpack.security.session.idleTimeout logo cloud

Ensures that user sessions will expire after a period of inactivity. This and xpack.security.session.lifespan are both highly recommended. You can also specify this setting for every provider separately. If this is set to 0, then sessions will never expire due to inactivity. By default, this value is 8 hours.

Use a string of <count>[ms\|s\|m\|h\|d\|w\|M\|Y] (e.g. 20m, 24h, 7d, 1w).

xpack.security.session.lifespan logo cloud

Ensures that user sessions will expire after the defined time period. This behavior is also known as an "absolute timeout". If this is set to 0, user sessions could stay active indefinitely. This and xpack.security.session.idleTimeout are both highly recommended. You can also specify this setting for every provider separately. By default, this value is 30 days.

Use a string of <count>[ms\|s\|m\|h\|d\|w\|M\|Y] (e.g. 20m, 24h, 7d, 1w).

xpack.security.session.cleanupInterval logo cloud

Sets the interval at which Kibana tries to remove expired and invalid sessions from the session index. By default, this value is 1 hour. The minimum value is 10 seconds.

Use a string of <count>[ms\|s\|m\|h\|d\|w\|M\|Y] (e.g. 20m, 24h, 7d, 1w).

xpack.security.session.concurrentSessions.maxSessions logo cloud
Set the maximum number of sessions each user is allowed to have active at any given time. By default, no limit is applied. If set, the value of this option should be an integer between 1 and 1000. When the limit is exceeded, the oldest session is automatically invalidated.

Encrypted saved objects settingsedit

These settings control the encryption of saved objects with sensitive data. For more details, refer to Secure saved objects.

xpack.encryptedSavedObjects.encryptionKey
An arbitrary string of at least 32 characters that is used to encrypt sensitive properties of saved objects before they’re stored in Elasticsearch. If not set, Kibana will generate a random key on startup, but certain features won’t be available until you set the encryption key explicitly.
xpack.encryptedSavedObjects.keyRotation.decryptionOnlyKeys
An optional list of previously used encryption keys. Like xpack.encryptedSavedObjects.encryptionKey, these must be at least 32 characters in length. Kibana doesn’t use these keys for encryption, but may still require them to decrypt some existing saved objects. Use this setting if you wish to change your encryption key, but don’t want to lose access to saved objects that were previously encrypted with a different key.

Audit logging settingsedit

You can enable audit logging to support compliance, accountability, and security. When enabled, Kibana will capture:

  • Who performed an action
  • What action was performed
  • When the action occurred

For more details and a reference of audit events, refer to Audit logs.

xpack.security.audit.enabled logo cloud

Set to true to enable audit logging`. Default: false

For example:

xpack.security.audit.enabled: true
xpack.security.audit.appender: 
  type: rolling-file
  fileName: ./logs/audit.log
  policy:
    type: time-interval
    interval: 24h 
  strategy:
    type: numeric
    max: 10 
  layout:
    type: json

This appender is the default and will be used if no appender.* config options are specified.

Rotates log files every 24 hours.

Keeps maximum of 10 log files before deleting older ones.
xpack.security.audit.appender
Optional. Specifies where audit logs should be written to and how they should be formatted. If no appender is specified, a default appender will be used (see above).
xpack.security.audit.appender.type

Required. Specifies where audit logs should be written to. Allowed values are console, file, or rolling-file.

Refer to file appender and rolling file appender for appender specific settings.

xpack.security.audit.appender.layout.type

Required. Specifies how audit logs should be formatted. Allowed values are json or pattern.

Refer to pattern layout for layout specific settings.

We recommend using json format to allow ingesting Kibana audit logs into Elasticsearch using Filebeat.

File appenderedit

The file appender writes to a file and can be configured using the following settings:

xpack.security.audit.appender.fileName
Required. Full file path the log file should be written to.

Rolling file appenderedit

The rolling-file appender writes to a file and rotates it using a rolling strategy, when a particular policy is triggered:

xpack.security.audit.appender.fileName
Required. Full file path the log file should be written to.
xpack.security.audit.appender.policy.type

Specifies when a rollover should occur. Allowed values are size-limit and time-interval. Default: time-interval.

Refer to size limit policy and time interval policy for policy specific settings.

xpack.security.audit.appender.strategy.type

Specifies how the rollover should occur. Only allowed value is currently numeric. Default: numeric

Refer to numeric strategy for strategy specific settings.

Size limit triggering policyedit

The size-limit triggering policy will rotate the file when it reaches a certain size:

xpack.security.audit.appender.policy.size
Maximum size the log file should reach before a rollover should be performed. Default: 100mb

Time interval triggering policyedit

The time-interval triggering policy will rotate the file every given interval of time:

xpack.security.audit.appender.policy.interval
How often a rollover should occur. Default: 24h
xpack.security.audit.appender.policy.modulate
Whether the interval should be adjusted to cause the next rollover to occur on the interval boundary. Default: true

Numeric rolling strategyedit

The numeric rolling strategy will suffix the log file with a given pattern when rolling over, and will retain a fixed number of rolled files:

xpack.security.audit.appender.strategy.pattern
Suffix to append to the file name when rolling over. Must include %i. Default: -%i
xpack.security.audit.appender.strategy.max
Maximum number of files to keep. Once this number is reached, oldest files will be deleted. Default: 7

Pattern layoutedit

The pattern layout outputs a string, formatted using a pattern with special placeholders, which will be replaced with data from the actual log message:

xpack.security.audit.appender.layout.pattern
Optional. Specifies how the log line should be formatted. Default: [%date][%level][%logger]%meta %message
xpack.security.audit.appender.layout.highlight
Optional. Set to true to enable highlighting log messages with colors.

Ignore filtersedit

xpack.security.audit.ignore_filters[] logo cloud

List of filters that determine which events should be excluded from the audit log. An event will get filtered out if at least one of the provided filters matches.

For example:

xpack.security.audit.ignore_filters:
- actions: [http_request] 
- categories: [database]
  types: [creation, change, deletion]

Filters out HTTP request events
