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.

Introducing Logstash

Logstash is an Elastic product built on Java that can provide multiple pipelines to move data into Elasticsearch via input and output plugins. Logstash uses various inputs to collect data, send it into Elasticsearch, and even enrich it along the way.

Input plugins

Input plugins allow specific datasets to be consumed and processed by Logstash. There are a tremendous number of plugins available for Logstash, and they are available for free and have varying levels of complexity.

Some of the most common plugins are the Syslog plugin, which reads Syslog events over the network, the Kafka plugin, which reads events from a Kafka topic, and the SNMP plugin, which polls network devices using Simple Network Management Protocol (SNMP).

Check out the available input plugins here: https://www.elastic.co/guide/en/logstash/current/input-plugins.html.

Filter plugins

As we mentioned, Logstash has the ability to apply filters to data as it travels through the pipeline...
