SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps diagnose and fix common security issues in Elasticsearch, such as authentication failures, authorization errors, TLS problems, and Kibana login issues, ensuring secure and uninterrupted access to your data.

Core Features & Use Cases

  • Diagnose Authentication Failures: Troubleshoot HTTP 401 errors and understand why users cannot authenticate.
  • Resolve Authorization Errors: Address HTTP 403 errors and ensure users have the correct permissions.
  • Fix TLS/SSL Issues: Identify and resolve certificate errors and handshake problems.
  • Troubleshoot API Keys: Investigate expired or invalid API keys and role mapping mismatches.
  • Kibana Login Issues: Resolve login failures, redirect loops, and CORS errors in Kibana.
  • License Expiry Recovery: Guide users through recovering from security lockouts due to expired licenses.
  • Use Case: A user reports they are receiving a "403 Forbidden" error when trying to access a specific index. This Skill can be used to determine if the user's roles are correctly mapped and if they possess the necessary privileges for that index.

Quick Start

Use the elasticsearch-security-troubleshooting skill to diagnose why a user is receiving a 401 authentication error when accessing the cluster.

Frequently Asked Questions about elasticsearch-security-troubleshooting

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I troubleshoot an Elasticsearch 401 authentication error?▼

Resolve Elasticsearch 401 authentication errors by using the `_security/_authenticate` API to verify credentials and diagnose why users cannot authenticate across self-managed, ECH, or Serverless deployments.

Why does my Elasticsearch user receive a 403 Forbidden error on a specific index?▼

An Elasticsearch 403 Forbidden error indicates an authorization failure where the user lacks necessary permissions. Use the `_security/user/_has_privileges` API to check if roles are correctly mapped and possess the required index privileges.

How do I fix TLS certificate handshake problems in Elasticsearch?▼

Fix Elasticsearch TLS certificate problems by diagnosing SSL handshake errors through the `_xpack` API, which helps identify misconfigured certificates and guides resolution steps based on your specific deployment type.

What is the best way to resolve Kibana login failures and redirect loops?▼

Resolve Kibana login failures and redirect loops by diagnosing security configurations, checking for CORS errors, and verifying that underlying Elasticsearch authentication and role mapping settings are correctly configured.

Does Elasticsearch security troubleshooting work for Serverless deployments?▼

Yes, Elasticsearch security troubleshooting supports self-managed, Elastic Cloud Hosted (ECH), and Serverless deployments, providing tailored resolution steps for API keys, authentication, and TLS issues across all environments.

How do I recover from an Elasticsearch security lockout due to an expired license?▼

Recover from an Elasticsearch security lockout caused by an expired license by following guided diagnostic steps to restore access, ensuring secure and uninterrupted data availability within your cluster.
