Open Distro for Elasticsearch Security

Open Distro for Elasticsearch Security is an Elasticsearch plugin that offers encryption, authentication, and authorization. When combined with Open Distro for Elasticsearch Security-Advanced Modules, it supports authentication via Active Directory, LDAP, Kerberos, JSON web tokens, SAML, OpenID and more. It includes fine grained role-based access control to indices, documents and fields. It also provides multi-tenancy support in Kibana.

Basic features provided by Security

  • Full data in transit encryption
  • Node-to-node encryption
  • Certificate revocation lists
  • Role-based cluster level access control
  • Role-based index level access control
  • User-, role- and permission management
  • Internal user database
  • HTTP basic authentication
  • PKI authentication
  • Proxy authentication
  • User Impersonation

Advance features included in Security Advanced Modules:

  • Active Directory / LDAP
  • Kerberos / SPNEGO
  • JSON web token (JWT)
  • OpenID Connect (OIDC)
  • SAML
  • Document-level security
  • Field-level security
  • Audit logging
  • Compliance logging for GDPR, HIPAA, PCI, SOX and ISO compliance
  • True Kibana multi-tenancy
  • REST management API

Documentation

Please refer to the technical documentation for detailed information on installing and configuring opendistro-elasticsearch-security plugin.

Quick Start

  • Install Elasticsearch

  • Install the opendistro-elasticsearch-security plugin for your Elasticsearch version 6.5.4, e.g.:

<ES directory>/bin/elasticsearch-plugin install \
  -b com.amazon.opendistroforelasticsearch:opendistro_security:0.8.0.0

  • cd into <ES directory>/plugins/opendistro_security/tools

  • Execute ./install_demo_configuration.sh, chmod the script first if necessary. This will generate all required TLS certificates and add the Security Plugin Configuration to your elasticsearch.yml file.

  • Start Elasticsearch

  • Test the installation by visiting https://localhost:9200. When prompted, use admin/admin as username and password. This user has full access to the cluster.

  • Display information about the currently logged in user by visiting https://localhost:9200/_opendistro/_security/authinfo.

Config hot reloading

The Security Plugin Configuration is stored in a dedicated index in Elasticsearch itself. Changes to the configuration are pushed to this index via the command line tool. This will trigger a reload of the configuration on all nodes automatically. This has several advantages over configuration via elasticsearch.yml:

  • Configuration is stored in a central place
  • No configuration files on the nodes necessary
  • Configuration changes do not require a restart
  • Configuration changes take effect immediately
