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.

Clicking on the Network tab will take you to an overview of the network data that is provided by the endpoints sending data into our Elastic Stack.

Similar to the Hosts section, there are protocol sections to allow you to review the more common network protocols, such as DNS, HTTP, and TLS. Flows are display data that doesn't fall into a parsed protocol, but is still recorded by Packetbeat.

Also, like the Hosts tab, you'll notice an External alerts section. This is where third-party network security solutions would report observations, such as Zeek or Suricata:

In this section, we introduced you to the Network section of the Security solution. Next, we'll explore Timelines, which is a powerful searching feature from within the Security solution.
