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.

Crafting a hypothesis

In a previous section, we explored the importance of crafting a specific and actionable threat hunting hypothesis. In addition, we looked at how threat intelligence can assist us with crafting a hypothesis. Another key dataset to leverage when crafting a hypothesis is the MITRE ATT&CK framework. In terms of crafting a specific hypothesis, this framework is excellent to drill down to a specific data point or points necessary to craft a solid hypothesis.

MITRE ATT&CK

In Chapter 17 there was an exploration of the MITRE ATT&CK framework, as it pertains to the incorporation of threat intelligence into incident response. The MITRE ATT&CK framework is also extremely useful in the initial planning and execution of a threat hunt. The MITRE ATT&CK framework is useful in a variety of areas in threat hunting, but for the purposes of this chapter, the focus will be on two specific use cases. First will be the use of the framework to craft a specific...
