Threat Hunting with Elastic Stack

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.

Cases

The Elastic cases feature is used to manage basic workflow and processes for observed events. This is not a full-blown case management solution; it is basic, with the intention that third-party connections are used for a proper case-management solution.

Cases can be created from the Alerts section by clicking on the folder icon, from a timeline, or from the Cases tab:

Figure 8.54 – Create cases from the Alerts page

Cases can also have templates added to them that aid in the investigation of events:

Clicking on the timeline icon will open a window that will allow you to select any available timeline:

Figure 8.56 – Adding a timeline to a case

We can add the timeline we created for the previously observed Agent Tesla infection. This adds the timeline as a Markdown hyperlink.

Once the case is created, we can make basic annotations and notes during our investigation. All of the comments render Markdown...
