This chapter covers the analysis of the data contained on an iPhone. It starts out by introducing the reader to several different analysis techniques. Some basic methods, such as mounting a disk image and viewing its file contents, as well as more advanced techniques, including analyzing an image within a hex editor, are discussed. Practical scenarios are applied for each technique in order to show an examiner all the steps needed to duplicate the command. Following the analysis techniques, the file system layout is discussed. In this section, the reader will gain an understanding of where each type of data can be found. The chapter is concluded with a mobile app reference section. Here, examiners can look through a list of specific applications and learn where the data for each is stored.
