Security settings in Elasticsearch

Security settings in Elasticsearch

edit

By default, X-Pack security is disabled when you have a basic or trial license. To enable X-Pack security, use the xpack.security.enabled setting.

You configure xpack.security settings to enable anonymous access and perform message authentication, set up document and field level security, configure realms, encrypt communications with SSL, and 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 Elasticsearch keystore. For more information about creating and updating the Elasticsearch keystore, see Secure settings.

General security settings

edit

xpack.security.enabled

Set to true to enable X-Pack security on the node.

If set to false, which is the default value for basic and trial licenses, X-Pack security is disabled. It also affects all Kibana instances that connect to this Elasticsearch instance; you do not need to disable X-Pack security in those kibana.yml files. For more information about disabling X-Pack security in specific Kibana instances, see Kibana security settings.

If you have gold or higher licenses, the default value is true; we recommend that you explicitly add this setting to avoid confusion.

xpack.security.hide_settings

A comma-separated list of settings that are omitted from the results of the 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.

Default password security settings

edit

xpack.security.authc.accept_default_password: In elasticsearch.yml, set this to false to disable support for the default "changeme" password.

Anonymous access settings

edit

You can configure the following anonymous access settings in elasticsearch.yml. For more information, see 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.

Document and field level security settings

edit

You can set the following document and field level security settings in elasticsearch.yml. For more information, see Setting up field and document level security.

xpack.security.dls_fls.enabled: Set to false to prevent document and field level security from being configured. Defaults to true.

Token service settings

edit

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.passphrase(Secure): [6.0.0] Deprecated in 6.0.0. A secure passphrase that must be the same on each node and greater than 8 characters in length. This passphrase is used to derive a cryptographic key with which the tokens will be encrypted and authenticated. If this setting is not used, the cluster automatically generates a key, which is the recommended method.
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.

Realm settings

edit

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

xpack.security.authc.realms:

    realm1:
        type: native
        order: 0
        ...

    realm2:
        type: ldap
        order: 1
        ...

    realm3:
        type: active_directory
        order: 2
        ...
    ...

The valid settings vary depending on the realm type. For more information, see User authentication.

edit

If an encryption key is configured (that is, either encryption.key or encryption.keystore.path is set), then X-Pack security publishes an encryption certificate when generating metadata and attempts to decrypt incoming SAML content. Encryption can be configured using the following settings:

encryption.key: Specifies the path to the PEM encoded private key to use for SAML message decryption. encryption.key and encryption.keystore.path cannot be used at the same time.
encryption.secure_key_passphrase (Secure): Specifies the passphrase to decrypt the PEM encoded private key (encryption.key) if it is encrypted.
encryption.certificate: Specifies the path to the PEM encoded certificate (or certificate chain) that is associated with the encryption.key. This certificate must also be included in the Service Provider metadata or manually configured within the IdP to enable message encryption. This setting can be used only if encryption.key is set.
encryption.keystore.path: The path to the keystore that contains a private key and certificate. Must be either a Java Keystore (jks) or a PKCS#12 file. encryption.key and encryption.keystore.path cannot be used at the same time.
encryption.keystore.type: The type of the keystore (encryption.keystore.path). Must be either jks or PKCS12. If the keystore path ends in ".p12", ".pfx", or "pkcs12", this setting defaults to PKCS12. Otherwise, it defaults to jks.
encryption.keystore.alias: Specifies the alias of the key within the keystore (encryption.keystore.path) that should be used for SAML message decryption. If not specified, all compatible key pairs from the keystore are considered as candidate keys for decryption.
encryption.keystore.secure_password (Secure): The password to the keystore (encryption.keystore.path).
encryption.keystore.secure_key_password (Secure): The password for the key in the keystore (encryption.keystore.path). Only a single password is supported. If you are using multiple decryption keys, they cannot have individual passwords.

SAML realm SSL settings

edit

If you are loading the IdP metadata over SSL/TLS (that is, idp.metadata.path is a URL using the https protocol), the following settings can be used to configure SSL. If these are not specified, then the default SSL settings are used.

These settings are not used for any purpose other than loading metadata over https.

The password to the keystore (ssl.keystore.path). This setting cannot be used with ssl.keystore.secure_password.

ssl.keystore.secure_password (Secure)

The password to the keystore (ssl.keystore.path). This setting cannot be used with ssl.keystore.password.

ssl.keystore.key_password

The password for the key in the keystore (ssl.keystore.path). Defaults to the keystore password. This setting cannot be used with ssl.keystore.secure_key_password.

ssl.keystore.secure_key_password (Secure)

The password for the key in the keystore (ssl.keystore.path). Defaults to the keystore password. This setting cannot be used with ssl.keystore.key_password.

See xpack.ssl.verification_mode for a more detailed explanation of these values.

ssl.supported_protocols

Specifies the supported protocols for TLS/SSL.

ssl.cipher_suites

Specifies the cipher suites that should be supported.

Load balancing and failover

edit

The load_balance.type setting can have the following values:

failover: The URLs specified are used in the order that they are specified. The first server that can be connected to will be used for all subsequent connections. If a connection to that server fails then the next server that a connection can be established to will be used for subsequent connections.
dns_failover: In this mode of operation, only a single URL may be specified. This URL must contain a DNS name. The system will be queried for all IP addresses that correspond to this DNS name. Connections to the Active Directory or LDAP server will always be tried in the order in which they were retrieved. This differs from failover in that there is no reordering of the list and if a server has failed at the beginning of the list, it will still be tried for each subsequent connection.
round_robin: Connections will continuously iterate through the list of provided URLs. If a server is unavailable, iterating through the list of URLs will continue until a successful connection is made.
dns_round_robin: In this mode of operation, only a single URL may be specified. This URL must contain a DNS name. The system will be queried for all IP addresses that correspond to this DNS name. Connections will continuously iterate through the list of addresses. If a server is unavailable, iterating through the list of URLs will continue until a successful connection is made.

Default TLS/SSL settings

edit

You can configure the following TLS/SSL settings in elasticsearch.yml. For more information, see Encrypting communications. These settings will be used for all of X-Pack unless they have been overridden by more specific settings such as those for HTTP or Transport.

xpack.ssl.supported_protocols

Supported protocols with versions. Valid protocols: SSLv2Hello, SSLv3, TLSv1, TLSv1.1, TLSv1.2. Defaults to TLSv1.2, TLSv1.1, TLSv1.

xpack.ssl.client_authentication

Controls the server’s behavior in regard to requesting a certificate from client connections. Valid values are required, optional, and none. required forces a client to present a certificate, while optional requests a client certificate but the client is not required to present one. Defaults to required. This global setting is not applicable for HTTP, see HTTP TLS/SSL Settings.

xpack.ssl.verification_mode

Controls the verification of certificates. Valid values are:

full, which verifies that the provided certificate is signed by a trusted authority (CA) and also verifies that the server’s hostname (or IP address) matches the names identified within the certificate.
certificate, which verifies that the provided certificate is signed by a trusted authority (CA), but does not perform any hostname verification.
none, which performs no verification of the server’s certificate. This mode disables many of the security benefits of SSL/TLS and should only be used after very careful consideration. It is primarily intended as a temporary diagnostic mechanism when attempting to resolve TLS errors, and its use on production clusters is strongly discouraged.

The default value is full.

xpack.ssl.cipher_suites

Supported cipher suites can be found in Oracle’s Java Cryptography Architecture documentation. Defaults to TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA. If the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files has been installed, the default value also includes TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA.

Default TLS/SSL key and trusted certificate settings

edit

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 X-Pack 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 key settings. The key and certificate must be in place for connections that require client authentication or when acting as a SSL enabled server.

PEM encoded files

edit

When using PEM encoded files, use the following settings:

xpack.ssl.key: Path to the PEM encoded file containing the private key.
xpack.ssl.key_passphrase: The passphrase that is used to decrypt the private key. This value is optional as the key might not be encrypted.
xpack.ssl.secure_key_passphrase (Secure): The passphrase that is used to decrypt the private key. This value is optional as the key might not be encrypted.
xpack.ssl.certificate: Path to a PEM encoded file containing the certificate (or certificate chain) that will be presented to clients when they connect.

xpack.ssl.truststore.secure_password (Secure): Password to the truststore.

Storing trusted certificates in a PKCS#12 file, although supported, is uncommon in practice. The elasticsearch-certutil tool, as well as Java’s keytool, are designed to generate PKCS#12 files that can be used both as a keystore and as a truststore, but this may not be the case for container files that are created using other tools. Usually, PKCS#12 files only contain secret and private entries. To confirm that a PKCS#12 container includes trusted certificate ("anchor") entries look for 2.16.840.1.113894.746875.1.1: <Unsupported tag 6> in the openssl pkcs12 -info output, or trustedCertEntry in the keytool -list output.

HTTP TLS/SSL Settings
