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.

Using threat hunting information to assist IR

While performing hunt operations, you'll likely identify events that will require an IR operation. Beyond the identification of potential intrusion events, threat hunters have an additional context that can assist in the response efforts.

As we discussed in Chapter 1, Introduction to Cyber Threat Intelligence, Analytical Models, and Frameworks, there are several models that we can use to inform response decisions by the IR team members.

Hunt and IR teams frequently work together during a response. It is important to remember to navigate this situation sensitively. While it may appear to the responders or traditional security teams that you've identified a defect in their defense in the network, you should always underscore that you are part of the team. You have helped to identify a potential intrusion against a large network that has many entry and exit points. The intrusion wasn't necessarily accomplished through a lack...
