FOR518 is the first non-vendor-based Mac and iOS incident response and forensics course that focuses students on the raw data, in-depth detailed analysis, and how to get the most out of their Mac and iOS cases. 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.
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.

What You Will Receive
This section introduces the student to Mac and iOS essentials such as acquisition, timestamps, logical file system, and disk structure. Acquisition fundamentals are the same with Mac and iOS devices, but there are a few tips and tricks that can be used to successfully and easily collect Mac and iOS systems for analysis. Students comfortable with Windows forensic analysis can easily learn the slight differences on a Mac system - the data are the same, only the format differs.
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.
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.
In addition to all the configuration and preference information found in the User Domain, the user can interact with a variety of native Apple applications, including the Internet, email, communication, photos, locational data, and others. These data can provide analysts with the who, what, where, why, and how for any investigation.
This section will explore the various databases and other files where data are being stored. The student will be able to parse this information by hand without the help of a commercial tool parser.
Mac systems implement some technologies that are available only to those with Mac and iOS devices. These include data backup with Time Machine, Document Versions, and iCloud, as well as disk encryption with FileVault. Other advanced topics include data hidden in encrypted containers, live response, Mac intrusion and malware analysis, and Mac memory analysis.
In this final course section, students will put their new Mac forensic skills to the test by running through a real-life scenario with team members.

Important! Bring your own system configured according to these instructions!
**************************IMPORTANT NOTE: MAC HARDWARE IS REQUIRED*************************************
A properly configured system is required to fully participate in this course. If you do not carefully read and follow these instructions, you will likely leave the class unsatisfied because you will not be able to participate in hands-on exercises that are essential to this course. Therefore, we strongly urge you to arrive with a system meeting all the requirements specified for the course.
It is critical that you follow the pre-class Mac System Setup Guide for your Mac. The guide is available at http://sans.org/security-resources/FOR518-laptop-setup-guide-v2.pdf. It is crucial that you read and follow the instructions in this pre-class Mac system setup guide before attending class the first day. The guide is a detailed step-by-step walk-through of a variety of downloads and configuration steps needed to prep your system for an in-depth and exciting week of Mac and iOS forensics. Please follow all of the steps correctly, otherwise your enjoyment of the class could be impacted. We recommend setting up your system at home, as hotel Internet might not be adequate to finalize the setup before class. Please do not wait until the night before class to go through the setup guide.
A properly configured Mac system is required for each student participating in this course. Before coming to class, carefully read and follow these instructions exactly.
MANDATORY FOR518 SYSTEM HARDWARE AND SOFTWARE REQUIREMENTS:
Your course media will now be delivered via download. The media files for class can be large, some in the 40 - 50 GB range. You need to allow plenty of time for the download to complete. Internet connections and speed vary greatly and are dependent on many different factors. Therefore, it is not possible to give an estimate of the length of time it will take to download your materials. Please start your course media downloads as you get the link. You will need your course media immediately on the first day of class. Waiting until the night before the class starts to begin your download has a high probability of failure.
SANS has begun providing printed materials in PDF form. Additionally, certain classes are using an electronic workbook in addition to the PDFs. The number of classes using eWorkbooks will grow quickly. In this new environment, we have found that a second monitor and/or a tablet device can be useful by keeping the class materials visible while the instructor is presenting or while you are working on lab exercises.
"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
"FOR518 is a great course for forensics people and organizations that use Mac within their environments, and the labs were really engaging. Sarah is an expert in this field and a great instructor, and she's really responsive to our comments and questions." - Ali Memarzia, Google
