This chapter illustrated the features of interest for iOS devices during mobile forensic activities. In particular, it introduced the different models with guidance on recognition techniques based on the model number or hardware model number. It also contained an introduction to the iOS operating system with particular reference to the filesystem (HFSX), the partitions (system and data), and the main data structures (
property list files and SQLite databases). These topics are the basics for forensic activity on an iDevice and will be useful inorder to understand the content of the next chapter, where you will learn various tools and techniques that you can use when dealing with acquisition and analysis.
