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.

Leveraging endpoint detection and response in your SOC

An EDR solution is a host-based security control to detect, prevent, and respond to security threats on your endpoint and infrastructure hosts. EDR solutions detect threats by continuously collecting and monitoring rich endpoint telemetry from the host operating system. The telemetry is analyzed on the endpoint, as it is collected to detect potential security issues.

EDR tools often focus on more dynamic behavioral aspects of threats rather than relying on signatures like traditional anti-virus tools. They search for indicators of attack (IOA), rather than looking for known malicious files. This allows EDR tools to scale against the millions of newly emerging modern threats that are often polymorphic in nature. Detections have complete contextual information as EDR tools have good visibility of all activities on the endpoint.

Endpoints generally have the largest attack surface in any environment, given the nature of how users...
