Security settings

The Security plugin provides a number of YAML configuration files that are used to store the necessary settings that define the way the Security plugin manages users, roles, and activity within the cluster. For a full list of the Security plugin configuration files, see Modifying the YAML files.

The following sections describe security-related settings in opensearch.yml. You can find the opensearch.yml in the <OPENSEARCH_HOME>/config/opensearch.yml. To learn more about static and dynamic settings, see Configuring OpenSearch.

Common settings

The Security plugin supports the following common settings:

  • plugins.security.nodes_dn (Static): Specifies a list of distinguished names (DNs) that denote the other nodes in the cluster. This setting supports wildcards and regular expressions. The list of DNs are also read from the security index in addition to the YAML configuration when plugins.security.nodes_dn_dynamic_config_enabled is true. If this setting is not configured correctly, the cluster will fail to form as the nodes will not be able to trust each other and will result in the following error: Transport client authentication no longer supported.

  • plugins.security.nodes_dn_dynamic_config_enabled (Static): Relevant for cross_cluster use cases where there is a need to manage the allow listed nodes_dn without having to restart the nodes every time a new cross_cluster remote is configured. Setting nodes_dn_dynamic_config_enabled to true enables super-admin callable Distinguished Names APIs, which provide means to update or retrieve nodes_dn dynamically. This setting only has effect if plugins.security.cert.intercluster_request_evaluator_class is not set. Default is false.

  • plugins.security.authcz.admin_dn (Static): Defines the DNs of certificates to which admin privileges should be assigned. Required.

  • plugins.security.roles_mapping_resolution (Static): Defines how backend roles are mapped to Security roles.

    Valid values are:

    • MAPPING_ONLY(Default): Mappings must be configured explicitly in roles_mapping.yml.
    • BACKENDROLES_ONLY: Backend roles are mapped to security roles directly. Settings in roles_mapping.yml have no effect.
    • BOTH: Backend roles are mapped to security roles both directly and through roles_mapping.yml.

  • plugins.security.dls.mode (Static): Sets the document-level security (DLS) evaluation mode. Default is adaptive. See How to set the DLS evaluation mode.

  • plugins.security.compliance.salt (Static): The salt to use when generating the hash value for field masking. Must be at least 32 characters. Only ASCII characters are allowed. Optional.

  • plugins.security.compliance.immutable_indices (Static): Documents in indexes that are marked as immutable follow the write-once, read-many paradigm. Documents created in these indexes cannot be changed and are therefore immutable.

  • config.dynamic.http.anonymous_auth_enabled (Static): Enables anonymous authentication. This will cause all HTTP authenticators to not challenge. Default is false.

  • http.detailed_errors.enabled (Static): Enables a detailed error message for REST calls performed against the OpenSearch cluster. If set to true, provides the root_cause together with the error code. Default is true.

REST management API settings

The Security plugin supports the following REST management API settings:

  • plugins.security.restapi.roles_enabled (Static): Enables role-based access to the REST management API for listed roles. Roles are separated by a comma. Default is an empty list (no role is allowed to access the REST management API). See Access control for the API.

  • plugins.security.restapi.endpoints_disabled.<role>.<endpoint> (Static): Disables specific endpoints and their HTTP methods for roles. Values for this setting compose an array of HTTP methods. For example: plugins.security.restapi.endpoints_disabled.all_access.ACTIONGROUPS: ["PUT","POST","DELETE"]. By default, all endpoints and methods are allowed. Existing endpoints include ACTIONGROUPS, CACHE, CONFIG, ROLES, ROLESMAPPING, INTERNALUSERS, SYSTEMINFO, PERMISSIONSINFO, and LICENSE. See Access control for the API.

  • plugins.security.restapi.password_validation_regex (Static): Specifies a regular expression to set the criteria for the login password. For more information, see Password settings.

  • plugins.security.restapi.password_validation_error_message (Static): Specifies an error message that loads when a password doesn’t pass validation. This setting is used in conjunction with plugins.security.restapi.password_validation_regex.

  • plugins.security.restapi.password_min_length (Static): Sets the minimum number of characters for the password length when using the score-based password strength estimator. The default is 8. This is also the minimum. For more information, see Password settings.

  • plugins.security.restapi.password_score_based_validation_strength (Static): Sets a threshold to determine whether the password is strong or weak. Valid values are fair, good, strong, and very_strong. This setting is used in conjunction with plugins.security.restapi.password_min_length.

  • plugins.security.unsupported.restapi.allow_securityconfig_modification (Static): Enables the use of the PUT and PATCH methods for the configuration APIs.

Advanced settings

The Security plugin supports the following advanced settings:

  • plugins.security.authcz.impersonation_dn (Static): Enables transport layer impersonation. This allows DNs to impersonate as other users. See User impersonation.

  • plugins.security.authcz.rest_impersonation_user (Static): Enables REST layer impersonation. This allows users to impersonate as other users. See User impersonation.

  • plugins.security.allow_default_init_securityindex (Static): When set to true, OpenSearch Security will automatically initialize the configuration index with the files in the /config directory if the index does not exist.

    This will use well-known default passwords. Use only in a private network/environment.

  • plugins.security.allow_unsafe_democertificates (Static): When set to true, OpenSearch starts up with demo certificates. These certificates are issued only for demo purposes.

    These certificates are well known and therefore unsafe for production. Use only in a private network/environment.

  • plugins.security.system_indices.permission.enabled (Static): Enables the system index permissions feature. When set to true, the feature is enabled and users with permission to modify roles can create roles that include permissions that grant access to system indexes. When set to false, the permission is disabled and only admins with an admin certificate can make changes to system indexes. By default, the permission is set to false in a new cluster.

Expert-level settings

An expert-level setting should only be configured and deployed by an admin who understands the feature completely. Misunderstandings of a feature can lead to security risks, cause the Security plugin to not operate properly, or cause data loss.

The Security plugin supports the following expert-level settings:

  • plugins.security.config_index_name (Static): The name of the index where .opendistro_security stores its configuration.

  • plugins.security.cert.oid (Static): Defines the Object Identifier (OID) of server node certificates.

  • plugins.security.cert.intercluster_request_evaluator_class (Static): Specifies the implementation of org.opensearch.security.transport.InterClusterRequestEvaluator that is used to evaluate intercluster requests. Instances of org.opensearch.security.transport.InterClusterRequestEvaluator must implement a single-argument constructor that takes an org.opensearch.common.settings.Settings object.

  • plugins.security.enable_snapshot_restore_privilege (Static): When set to false, this setting disables snapshot restore for regular users. In this case, only snapshot restore requests signed by an admin TLS certificate are accepted. When set to true (default), regular users can restore snapshots if they have the cluster:admin/snapshot/restore, indices:admin/create, and indices:data/write/index privileges.

    A snapshot can only be restored when it does not contain global state and does not restore the .opendistro_security index.

  • plugins.security.check_snapshot_restore_write_privileges (Static): When set to false, additional index checks are omitted. When set to the default of true, attempts to restore snapshots are evaluated for indices:admin/create and "indices:data/write/index.

  • plugins.security.cache.ttl_minutes (Static): Determines how long it takes for authentication caching to time out. The authentication cache helps speed up authentication by temporarily storing user objects returned from the backend so that the Security plugin is not required to make repeated requests for them. Set the value in minutes. The default is 60. Disable caching by setting the value to 0.

  • plugins.security.disabled (Static): Disables OpenSearch Security.

    Disabling this plugin can expose your configuration (including passwords) to the public.

  • plugins.security.protected_indices.enabled (Static): If set to true, enables protected indexes. Protected indexes are even more secure than regular indexes. These indexes require a role to access like any other traditional index and require an additional role to be visible. This setting is used in conjunction with the plugins.security.protected_indices.roles and plugins.security.protected_indices.indices settings.

  • plugins.security.protected_indices.roles (Static): Specifies a list of roles to which a user must be mapped to access protected indexes.

  • plugins.security.protected_indices.indices (Static): Specifies a list of indexes to mark as protected. These indexes will only be visible to users mapped to the roles specified in plugins.security.protected_indices.roles. After this requirement is fulfilled, a user will still need to be mapped to the traditional role used to grant access permission to the index.

  • plugins.security.system_indices.enabled (Static): If set to true, enables system indexes. System indexes are similar to the security index, except that the contents are not encrypted. Indexes configured as system indexes can be accessed by either a super-admin or a user with a role that includes the system index permission. For more information about system indexes, see System indexes.

  • plugins.security.system_indices.indices (Static): A list of indexes to be used as system indexes. This setting is controlled by the plugins.security.system_indices.enabled setting.

  • plugins.security.allow_default_init_securityindex (Static): When set to true, sets the Security plugin to its default security settings if an attempt to create the security index fails when OpenSearch launches. Default security settings are stored in YAML files contained in the opensearch-project/security/config directory. Default is false.

  • plugins.security.cert.intercluster_request_evaluator_class (Static): A class to be used for evaluating intercluster communication.

  • plugins.security.enable_snapshot_restore_privilege (Static): Enables granting the snapshot restore privilege. Optional. Default is true.

  • plugins.security.check_snapshot_restore_write_privileges (Static): Enforces write privilege evaluation when creating snapshots. Default is true.

  • plugins.security.password.hashing.algorithm: (Static): Specifies the password hashing algorithm to use.

    Valid values are:

    • BCrypt (Default)
    • PBKDF2

  • plugins.security.password.hashing.bcrypt.rounds (Static): Specifies the number of rounds to use for password hashing with BCrypt. Valid values are between 4 and 31, inclusive. Default is 12.

    Valid values are:

    • A
    • B
    • Y (Default)

    Valid values are:

    • SHA1
    • SHA224
    • SHA256 (Default)
    • SHA384
    • SHA512

  • plugins.security.password.hashing.pbkdf2.iterations (Static): Specifies the number of times that the pseudo-random function is applied to the password. Default is 600,000.
