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.

Elastic solutions

Elastic uses the concept of solutions to organize ways that the stack can be used to solve use cases. The three solutions are as follows:

  • Search: Enterprise Search
  • Observe: Health and performance logging and metrics
  • Security: Threat detection and response

We're going to be focused on the Security solution. That said, now that you have Kibana running, you can explore the Enterprise Search and Observability solutions. They are all available and have no cost. The very basic data that we have sent into the stack so far won't populate much, if any, of those solutions; so beyond being able to see the interface, there isn't much else to do.

As the Security solution has access to endpoint data, complete visibility into the collections apparatus and capabilities, and the ability to modify the protective posture of the environment, Elastic has required extensive configuration to ensure that the data is secure. We're going to go over that...
