Getting Started with Elastic Stack 8.0

By: Asjad Athick

Overview of this book

The Elastic Stack helps you work with massive volumes of data to power use cases in the search, observability, and security solution areas. This three-part book starts with an introduction to the Elastic Stack with high-level commentary on the solutions the stack can be leveraged for. The second section focuses on each core component, giving you a detailed understanding of the component and the role it plays. You’ll start by working with Elasticsearch to ingest, search, analyze, and store data for your use cases. Next, you’ll look at Logstash, Beats, and Elastic Agent as components that can collect, transform, and load data. Later chapters help you use Kibana as an interface to consume Elastic solutions and interact with data on Elasticsearch. The last section explores the three main use cases offered on top of the Elastic Stack. You’ll start with a full-text search and look at real-world outcomes powered by search capabilities. Furthermore, you’ll learn how the stack can be used to monitor and observe large and complex IT environments. Finally, you’ll understand how to detect, prevent, and respond to security threats across your environment. The book ends by highlighting architecture best practices for successful Elastic Stack deployments. By the end of this book, you’ll be able to implement the Elastic Stack and derive value from it.

Building a SIEM for your SOC

We looked at some of the objectives of a modern security operations center to effectively protect your organization from security threats. This section describes the necessary technology or tooling investments required to achieve these objectives.

A SIEM solution can help security teams turn logs, metrics, and other sources of security telemetry from across your organization into actionable insight. This insight helps teams achieve a range of SOC objectives, including being able to detect and remediate threats, understand their security posture, investigate issues, and stay compliant with appropriate policies and standards.

Let's look at some important requirements when it comes to designing your SIEM platform, and how the Elastic Stack can be leveraged to implement some of the capabilities.
