By: Pranav Shukla, Sharath Kumar M N

Overview of this book

The Elastic Stack is a powerful combination of tools that help in performing distributed search, analytics, logging, and visualization of data. Elastic Stack 7.0 encompasses new features and capabilities that will enable you to find unique insights into analytics using these techniques. This book will give you a fundamental understanding of what the stack is all about, and guide you in using it efficiently to build powerful real-time data processing applications. The first few sections of the book will help you understand how to set up the stack by installing tools and exploring their basic configurations. You’ll then get up to speed with using Elasticsearch for distributed search and analytics, Logstash for logging, and Kibana for data visualization. As you work through the book, you will discover the technique of creating custom plugins using Kibana and Beats. This is followed by coverage of the Elastic X-Pack, a useful extension for effective security and monitoring. You’ll also find helpful tips on how to use Elastic Cloud and deploy Elastic Stack in production environments. By the end of this book, you’ll be well-versed with fundamental Elastic Stack functionalities and the role of each component in the stack to solve different data processing problems.

Securing Elasticsearch and Kibana

The components of Elastic Stack are unsecured, as it doesn't have inherent security built into it; this means it can be accessed by anyone. This poses a security risk when running Elastic Stack in production. In order to prevent unauthorized access in production, different mechanisms of imposing security, such as running Elastic Stack behind a firewall and securing via reverse proxies (such as nginx, HAProxy, and so on), are employed. offers a commercial product to secure Elastic Stack. This offering is part of X-Pack and the module is called Security.

The X-Pack security module provides the following ways to secure Elastic Stack:

  • User authentication and user authorization
  • Node/Client authentication and channel encryption
  • Auditing
