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 third edition will help you perform cutting-edge digital forensic activities and incident response with a new focus on responding to ransomware attacks. After covering the fundamentals of incident response that are critical to any information security team, you’ll explore incident response frameworks. From understanding their importance to creating a swift and effective response to security incidents, the book will guide you using examples. Later, you’ll cover digital forensic techniques, from acquiring evidence and examining volatile memory through to hard drive examination and network-based evidence. You’ll be able to apply these techniques to the current threat of ransomware. As you progress, you’ll discover the role that threat intelligence plays in the incident response process. You’ll also learn how to prepare an incident response report that documents the findings of your analysis. Finally, in addition to various incident response activities, the book will address malware analysis and demonstrate how you can proactively use your digital forensic skills in threat hunting. By the end of this book, you’ll be able to investigate and report unwanted security breaches and incidents in your organization.

Tools for imaging

As with much of the previous material we covered, there are several tools available to a responder for imaging drives. Understanding these tools provides responders with knowledge about which tool to apply to an incident.

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...
