Elasticsearch provides several security features to help protect clusters and the data they contain from unauthorized access and other security threats. Here are some of the different types of Elasticsearch security features:
1. Authentication: Elasticsearch supports various mechanisms for authentication, such as username and password, Kerberos, and LDAP. This ensures that only authorized users can access the Elasticsearch cluster.
2. Authorization: Elasticsearch provides role-based access control (RBAC) to control access to specific actions within the cluster, such as indexing, searching, and managing indices.
3. Encryption: Elasticsearch supports SSL/TLS encryption to ensure that network traffic between clients and the cluster is encrypted and secure.
4. Auditing: Elasticsearch provides auditing features to track user actions and system events within the cluster. This can help detect and investigate security incidents.
5. Security plugins: Elasticsearch provides several security plugins, such as the X-Pack Security plugin, which adds additional security features such as field-level security and audit logging.
6. Integrations with external security systems: Elasticsearch can integrate with external security systems, such as SAML and Apache Ranger, to provide additional security features such as single sign-on (SSO) and centralized management of user access.
Overall, Elasticsearch provides a range of security features to help protect clusters and the data they contain from security threats, and can be customized based on specific security requirements.
