Network Security Through Data Analysis

Part III. Analytics

In the previous two sections of the book, we’ve discussed the types of data you can collect, and tools for manipulating that data. In this section, we focus on taking that data and conducting analyses on that.

Each chapter in the following section focuses on a different family of mathematical and analytical techniques that can be used on data. The focus of each chapter is on providing information that is more security-relevant or floor-relevant. Chapter 10 focuses on the process of Exploratory Data Analysis (EDA), and should be read before anything else. Chapter 11, Chapter 12, Chapter 13, and Chapter 14 provide examples of behaviors, relate them to attacks, and discuss ways that these behaviors can be used to construct alarms or be used for forensics and investigation. Chapter 15 looks at the problem of mapping a network, applying the techniques in the previous chapters to provide situational awareness.
