Additional Security Features
Password Policies
Enforcing password policies ensures that users use strong passwords. This can be configured in the elasticsearch.yml file:
xpack.security.authc.password_hashing.algorithm: bcrypt
xpack.security.authc.password_min_length: 8
xpack.security.authc.password_complexity: high
IP Filtering
Restrict access to your Elasticsearch cluster based on IP addresses. This can be configured using the xpack.security.http.filter settings in the elasticsearch.yml file:
xpack.security.http.filter.allow: ["192.168.1.0/24"]
xpack.security.http.filter.deny: ["0.0.0.0/0"]
Auditing
Enabling auditing allows you to track security-related events. Configure auditing in the elasticsearch.yml file:
xpack.security.audit.enabled: true
xpack.security.audit.logfile.events.emit_request_body: true
Audit logs can help in monitoring and troubleshooting security-related incidents.
Elasticsearch Basic Authentication for Cluster
Elasticsearch is a powerful distributed search and analytics engine commonly used for logging, monitoring, and data analysis. Security is paramount when dealing with sensitive data, and basic authentication is one of the fundamental methods to ensure that only authorized users can access your Elasticsearch cluster.
This article provides a detailed guide on setting up basic authentication for an Elasticsearch cluster, complete with examples and outputs. The guide is designed to be easy to understand and beginner-friendly.
