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.

Enrichments within Elastic

The Elastic Security app currently has IP reputation links that can be used to gain additional information about threat detections. To use these, simply click on an IP address of interest from within a timeline to be sent to either VirusTotal or Talos Intelligence and automatically perform a search for the IP address. Additional indicator types will hopefully be added in the future:

Figure 11.11 – IP reputation checking from within Elastic

In the preceding screenshot, you can see the IP address 64.225.18.241 has been identified in a timeline. From here we can click on the IP address and the network details flyout pane has hyperlinks that we can click on for VirusTotal and Talos Intelligence that will provide us with additional enrichments on this IP address.

In this section, we saw how we can use the timeline feature of the Elastic Security app to perform enrichments for IP addresses.
