I have not encountered a Mac class this in-depth that covers the file structure so well.
Solid background for investigations new to Mac.
Digital forensic and incident response investigators have traditionally dealt with Windows machines, but what if they find themselves in front of a new Apple Mac or iDevice? The increasing popularity of Apple devices can be seen everywhere, from coffee shops to corporate boardrooms. Dealing with these devices as an investigator is no longer a niche skill - every analyst must have the core skills necessary to investigate the Apple devices they encounter.
The constantly updated FOR518: Mac and iOS Forensic Analysis and Incident Response course provides the techniques and skills necessary to take on any Mac or iOS case without hesitation. The intense hands-on forensic analysis and incident response skills taught in the course will enable analysts to broaden their capabilities and gain the confidence and knowledge to comfortably analyze any Mac or iOS device. In addition to traditional investigations, the course presents intrusion and incident response scenarios to help analysts learn ways to identify and hunt down attackers that have compromised Apple devices.
Forensicate Differently!
FOR518: Mac and iOS Forensic Analysis and Incident Response will teach you:
- Mac and iOS Fundamentals: How to analyze and parse the Hierarchical File System (HFS+) and Apple File System (APFS) by hand and recognize the specific domains of the logical file system and Mac-specific file types.
- User Activity: How to understand and profile users through their data files and preference configurations.
- Advanced Intrusion Analysis and Correlation: How to determine how a system has been used or compromised by using the system and user data files in correlation with system log files.
- Apple Technologies: How to understand and analyze many Mac and iOS-specific technologies, including Time Machine, Spotlight, iCloud, Document Versions, FileVault, Continuity, and FaceTime.
FOR518: Mac and iOS Forensic Analysis and Incident Response aims to train a well-rounded investigator by diving deep into forensic and intrusion analysis of Mac and iOS. The course focuses on topics such as the HFS+ and APFS file systems, Mac-specific data files, tracking of user activity, system configuration, analysis and correlation of Mac logs, Mac applications, and Mac-exclusive technologies. A computer forensic analyst who completes this course will have the skills needed to take on a Mac or iOS forensics case.

The building blocks of Mac and iOS forensics start with a thorough understanding of the HFS+. Utilizing a hex editor, students will learn the basic principles of the primary file system implemented on MacOS systems. Students will then use that information to look at a variety of great artifacts that use the file system and that are different from other operating systems students have seen in the past. Rounding out the day, students will review Mac and iOS triage data.

FOR518.3: User Data, System Configuration, and Log Analysis
Staff
Wed Jun 24th, 2020
9:00 AM - 5:00 PM
Overview
This section contains a wide array of information that can be used to profile and understand how individuals use their computers. The logical Mac file system is made up of four domains: User, Local, System, and Network. The User Domain contains most of the user-related items of forensic interest. This domain consists of user preferences and configurations.
The Local and System Domains contain system-specific information such as application installation, system settings and preferences, and system logs. This section details basic system information, GUI preferences, and system application data. A basic analysis of system logs can provide a good understanding of how a system was used or abused. The Network domain is more ethereal and we can find this in many places throughout the course as well as in the logs.
Timeline analysis tells the story of how the system was used. Each entry in a log file has a specific meaning and may be able to tell how the user interacted with the computer. The log entries can be correlated with other data found on the system to create an in-depth timeline that can be used to solve cases quickly and efficiently. Analysis tools and techniques will be used to correlate the data and help the student put the story back together in a coherent and meaningful way.

Author Statement
"This course is designed to enable an analyst comfortable in Windows-based forensics to perform just as well on a Mac. The Mac and iOS market share is ever-increasing, and the Apple is now a popular platform for many companies and government entities. I believe a well-rounded forensic analyst is an extremely well-prepared and employable individual in a Windows forensics world. Windows analysis is the base education in the competitive field of digital forensics, but any additional skills you can acquire can set you apart from the crowd, whether it is Mac, mobile, memory, or malware analysis.
Mac and iOS forensics is truly a passion of mine that I genuinely want to share with the forensics community. While you may not work on a Mac or iOS investigation every day, the tools and techniques you learn in this course will help you with other investigations including Windows, Linux, and mobile." - Sarah Edwards
