Overview of this book

An understanding of how digital forensics integrates with the overall response to cybersecurity incidents is key to securing your organization's infrastructure from attacks. This updated second edition will help you perform cutting-edge digital forensic activities and incident response. After focusing on the fundamentals of incident response that are critical to any information security team, you’ll move on to exploring the incident response framework. From understanding its importance to creating a swift and effective response to security incidents, the book will guide you with the help of useful examples. You’ll later get up to speed with digital forensic techniques, from acquiring evidence and examining volatile memory through to hard drive examination and network-based evidence. As you progress, you’ll discover the role that threat intelligence plays in the incident response process.

Imaging tools

While there is no court or legal body that certifies digital forensics imaging tools, there are several methods and associated tools that represent best practices when acquiring disk evidence. Let's go over these now:

  • FTK Imager: FTK Imager is provided as a free software application by Access Data. This GUI-based application allows for the forensically sound acquisition of logical and physical volumes, memory, and other protected files and outputs those images in a variety of formats. In addition, FTK Imager Lite is a self-contained application that can be run on removable media for the acquisition of digital evidence from running systems (this will be covered in detail later in this chapter).
  • EnCase Imager: Provided by Guidance Software, EnCase Imager is another forensic application that allows responders to acquire digital evidence from a variety of systems...
