Overview of this book

Elastic Stack, previously known as the ELK stack, is a log analysis solution that helps users ingest, process, and analyze search data effectively. With the addition of machine learning, a key commercial feature, the Elastic Stack makes this process even more efficient. This updated second edition of Machine Learning with the Elastic Stack provides a comprehensive overview of Elastic Stack's machine learning features for both time series data analysis as well as for classification, regression, and outlier detection. The book starts by explaining machine learning concepts in an intuitive way. You'll then perform time series analysis on different types of data, such as log files, network flows, application metrics, and financial data. As you progress through the chapters, you'll deploy machine learning within Elastic Stack for logging, security, and metrics. Finally, you'll discover how data frame analysis opens up a whole new set of use cases that machine learning can help you with. By the end of this Elastic Stack book, you'll have hands-on machine learning and Elastic Stack experience, along with the knowledge you need to incorporate machine learning in your distributed search and data analysis platform.

Anomaly detection in the Elastic Security app

Elastic Security is truly the quintessence of a purpose-driven application in the Elastic Stack. Created from the ground up with the security analyst's workflow in mind, the comprehensiveness of the Elastic Security app could fill an entire book on its own. However, the heart of the Elastic Security app is the Detections feature in which user- and Elastic-created rules execute to create alerts when rules' conditions are met. As we'll see, Elastic ML plays a significant role in the Detections feature.

Prebuilt anomaly detection jobs

The majority of the detection rules in Elastic Security are static, but many are backed by prebuilt anomaly detection jobs that operate on the data collected from Elastic Agent or Beats, or equivalent data that conforms with the ECS fields that are applicable for each job type.
