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.

Configuring Winlogbeat and Packetbeat

As stated in Chapter 3, Introduction to the Elastic Stack, Winlogbeat is a data shipper for Windows events and Packetbeat is a data shipper for application-type network events. Both provide a tremendous amount of information by tracking endpoint and network data when threat hunting.

Installing Beats

Let's download Winlogbeat and Packetbeat, apply some configuration, and run them as services. First, we need to collect the binaries, so from the Windows VM, do the following:

  • Download Winlogbeat (the x64 ZIP file, not the MSI version):
  • Download Packetbeat (the x64 ZIP file, not the MSI version):
  • Download Npcap (Npcap, not Nmap):

Find the winlogbeat-{version} file that was downloaded, right-click it, and extract it to the c:\Program Files directory.

Next, we need to create a Java KeyStore so our Beat can authenticate to Elasticsearch. Just like when we did this for Kibana, you'll need to use the...
