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.

The Administration tab allows us to review the status of all of the endpoints that are reporting to our Elastic Stack.

Additionally, we can add trusted applications that we don't want to generate alerts from. Great examples could be legacy anti-virus, asset management tools, or vulnerability scanners:

Figure 8.58 – Adding trusted applications

We can name the application, select the appropriate operating system, and define a path, filename, or hash value. We can select multiple fields, so if there is a file that is trusted but could also be abused, we could define the name, hash, and location:

Figure 8.59 – Adding trusted applications

We can monitor all of our trusted applications and see some information about them.

In this section, we discussed the administration of the Elastic Security solution, specifically the endpoints and the trusted applications.
