Chapter 29 Mac Memory Overview

This chapter introduces a wide range of topics related to Mac memory forensics, including process analysis, recovery of cached files from memory, finding historical artifacts, and locating and extracting loaded kernel extensions. This chapter also highlights the similarities between analyzing Mac and Linux systems. Because these systems are both based on UNIX, our goal with this chapter is to introduce Mac-specific data structures and constructs without repeating information found in the Linux chapters. This chapter concludes with utilities that you can use to conduct live forensics of Mac systems. If you are familiar with performing live analysis on Linux, there might be a bit of a learning curve because many of the normal tools and techniques are not directly applicable to Mac OS X.

Mac versus Linux Analysis

In Part III of the book, which discusses Linux forensics analysis, we cover a number of Volatility plugins, data structures, algorithms, rootkit techniques, detection capabilities, and other essential topics for when you perform memory forensics on Linux systems. As you will learn, Mac and Linux share many similarities, including adherence to the Portable Operating System Interface (POSIX) standard, which greatly influences operating system design, as well as the use of libc, bash, and other libraries and applications that are the foundation of the respective operating systems. Due to the great number of similarities and overlapping codebases, ...
