Overview of this book

Professionals working in the mobile forensics industry will be able to put their knowledge to work with this practical guide to learning how to extract and analyze all available data from an iOS device. This book is a comprehensive, how-to guide that leads investigators through the process of collecting mobile devices and preserving, extracting, and analyzing data, as well as building a report. Complete with step-by-step explanations of essential concepts, practical examples, and self-assessment questions, this book starts by covering the fundamentals of mobile forensics and how to overcome challenges in extracting data from iOS devices. Once you've walked through the basics of iOS, you’ll learn how to use commercial tools to extract and process data and manually search for artifacts stored in database files. Next, you'll find out the correct workflows for handling iOS devices and understand how to extract valuable information to track device usage. You’ll also get to grips with analyzing key artifacts, such as browser history, the pattern of life data, location data, and social network forensics. By the end of this book, you'll be able to establish a proper workflow for handling iOS devices, extracting all available data, and analyzing it to gather precious insights that can be reported as prosecutable evidence.

Chapter 7: Analyzing Connectivity Data

In the previous chapter, we introduced location-related artifacts and learned how an investigation can leverage such data to obtain a general geographical location of where the device may have been. In this chapter, we will focus on connectivity data.

The modern mobile phone has evolved from being a simple handheld device that's used to communicate via voice into a mobile computing device that communicates with the internet. Almost every interaction between a device and the external world is logged by the operating system, so it shouldn't come as a surprise that connectivity data has become the single most important source of evidence in virtually every type of investigation: artifacts such as call logs and internet navigation history are invaluable for the modern investigator.

We'll start this chapter by looking at cellular-related artifacts, contacts, and phone calls, including FaceTime videocalls. Then, we'll learn...
