Computer Forensics Essential Training
Video duration: 0s 1h 57m Intermediate


Computer forensics is used to find legal evidence in computers or storage devices. Although this course won't teach you how to become a digital forensics detective, it will cover the basics of this growing (and exciting) technical field. Author Jungwoo Ryoo reviews the basics: the goals of computer forensics, the types of investigations it's used for, a forensic investigator's typical toolset, and the legal implications of this type of work. Then he'll show how to prepare for an investigation; acquire data "live" while the system is running, statically from a hard drive, or from a remote machine; make sure data is kept in its original state with software and hardware write blockers; analyze the data; and create a report of your findings. Jungwoo uses a combination of open-source and commercial software, so you'll be able to uncover the information you need with the tools that are in your budget.

Topics include:
  • Understanding computer forensics
  • Understanding partitioning
  • Using a hex editor
  • Preparing a target drive
  • Acquiring data
  • Ensuring data integrity with hashing
  • Indexing and searching
  • Generating a report


Hi, my name is Jungwoo Ryoo and welcome to Computer Forensics Essential Training. This course provides an introduction to computer forensics by Going over all the major aspects of computer forensics. By the end of this course, you will have a good understanding of what computer forensics is all about. We'll start with preparing for computer forensics investigations. In this chapter, we'll be using softer and harder write blockers to protect your evidence.

In the next chapter, we'll be using hashing tools, such as md five sum, to verify the validity of your evidence. Next, we'll learn how to acquire data using a commercial data acquisition software such as FDK Imager. Finally, we'll be analyzing the acquired data using open source computer forensics software suite called Autopsy. Now let's get started with Computer Forensics Essential Training.

Q: Which operating systems support built-in write blocking?
A: Microsoft introduced the registry concept into its OS with the release of Windows 95. As a result, registry-based write blocking has been available since then. In this course, we tested registry-based write blocking on both Windows 7 and Windows 8.
If for whatever reason your OS doesn’t support registry-based write blocking, you can enable software-based write blocking via a forensics software suite such as EnCase. Finally, If all fails, you can always use hardware write blockers.
Q: Are there other ways to access deleted files in the usbimage.001 file?
A:  When opening the usbimage.001 file in Autopsy and trying to recover the deleted file (i.e. dreamCar.jpg), as shown the chapter 5 movie “Searching,” if you don’t see the deleted file in the Data Sources tree, you can still view and extract the deleted file in the Views tree as shown below.
