Digital Forensics & Incident Response

Andrew Case & Jamie Levy | July 22-25



Overview

Digital forensics and incident response are two of the most critical fields in all of information security. The staggering number of reported breaches in the last several years has shown that the ability to rapidly respond to attacks is a vital capability for all organizations. Unfortunately, the standard IT staff member is simply unable to effectively respond to security incidents. Successful handling of these situations requires specific training in a number of deeply technical areas including file systems, operating system design, and knowledge of possible network and host attack vectors.

During this training, students will learn both the theory around digital forensics and incident response as well as gain valuable hands-on experience with the same types of evidence and situations they will see in real-world investigations. The class is structured so that a specific analysis technique is discussed and then the students immediately analyze staged evidence using their newly gained knowledge. Not only does this approach reinforce the material learned, but it also gives the investigator a number of new skills as the course proceeds.

This course, which has been offered to a wide range of students for several years, has been updated with new analysis techniques, completely revamped labs, and full coverage of Windows 8 and Windows 10 forensics. Upon completion of the training, students will be able to effectively preserve and analyze a large number of digital evidence sources, including both on-disk and in-memory data, using the latest and most effective forensics tools and techniques. These skills will be immediately usable in a number of investigative scenarios, and will greatly enhance even experienced investigators' skillset. Students will also leave with media that contains all the tools and resources used throughout the training.

Who Should Take this Course

Network and systems administrators, digital forensics staff, incident response handlers, SOC team members, and managers in the IT and IT security realm

Student Requirements

The course assumes previous forensics knowledge equivalent to that of a junior investigator. Systems administrators and other IT staff often have these skills even if they were never applied to forensics. The hands-on exercises are designed to provide a learning experience to investigators of all skill levels (there will be different objectives based on previous skill-set). Scripting experience (python, perl, ruby, etc.) will be helpful, but not required, to automate the analysis and reporting of results from the exercises.

What Students Should Bring

Hardware:

Laptop with the following minimum specifications:
  • 2.0 GHz, multi-core CPU
  • 4 GB of RAM
  • 20 GB of disk space
  • USB 2.0/3.0 ports
  • Wireless Network Interface Card if internet access is desired

Software:

Laptops must have access to a Windows installation either as a virtual machine or on the laptop directly. VMware Workstation, Player, or Fusion must be installed. A PDF reader is also required. If students wish to examine evidence from their own Windows installation, they must have a decompression tool that can handle a wide variety of formats (tar, gzip, bzip, RAR, etc) installed. 7zip and WinRar meet this criteria and are free.

What Students Will Be Provided With

A USB drive with:
  • A Linux VM setup with the needed Linux tools installed
  • All of the Windows forensics tools
  • All of the lab material
  • Select relevant reading material such as whitepapers and presentations
