Threat Hunting with Elastic Stack

5 (1)
By: Andrew Pease

Overview of this book

Threat Hunting with Elastic Stack will show you how to make the best use of Elastic Security to provide optimal protection against cyber threats. With this book, security practitioners working with Kibana will be able to put their knowledge to work and detect malicious adversary activity within their contested network. You'll take a hands-on approach to learning the implementation and methodologies that will have you up and running in no time. Starting with the foundational parts of the Elastic Stack, you'll explore analytical models and how they support security response and finally leverage Elastic technology to perform defensive cyber operations. You’ll then cover threat intelligence analytical models, threat hunting concepts and methodologies, and how to leverage them in cyber operations. After you’ve mastered the basics, you’ll apply the knowledge you've gained to build and configure your own Elastic Stack, upload data, and explore that data directly as well as by using the built-in tools in the Kibana app to hunt for nefarious activities. By the end of this book, you'll be able to build an Elastic Stack for self-training or to monitor your own network and/or assets and use Kibana to monitor and hunt for adversaries within your network.

Section 2: Leveraging the Elastic Stack for Collection and Analysis
Section 3: Operationalizing Threat Hunting

The Visualize app

Now that we've experimented with a few searches and received the resulting text, let's try to visualize it in a way that we can display the data so it can be consumed at a glance to understand the operational security picture as well as to facilitate actual threat hunting.

As before, start up both your Elastic and victim VMs and ensure that the event data is being reported into Elastic. Additionally, we'll be using the three saved searches you created during The Discover app section at the beginning of the chapter. If you don't have these searches saved, please refer to those sections.

All of the visualizations are extremely interactive, and they allow you to hover over them to get introspection into a specific data point or to click and apply filters directly to the visualization.

Click on the hamburger menu and then select the Visualize App.
