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.

Introducing threat hunting

As the computing age was blossoming, we started creating more data and that data became ever more valuable than the data before it. As data became more valuable, there were others who were not meant to have access to data who wanted it. This created the first information security teams – groups that identify unauthorized access to systems, chase down aggressors, and evict them from the contested network. Threat hunting was "a thing" before it had a name.

The problem with this early approach to information security/security operations was that it was very reactionary and as our data continued its climb in value, adversaries became more incentivized to pilfer this data. We, as defenders, needed to get in front of the compromises and identify the threats and capabilities of adversaries and adapt our security countermeasures to proactively defend our environment. In the event a compromise occurred, we needed to understand the extent of the...
