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.

Leveraging Threat Intelligence

One area of incident response that has had a significant impact on an organization’s ability to respond to cyberattacks is the use of cyber threat intelligence or, simply, threat intelligence. The term Cyber Threat Intelligence covers a wide range of information, data points, and techniques that allow analysts to identify attack types in their network, adequately respond to them, and prepare for future attacks. To be able to properly leverage this capability, information security analysts should have a solid foundation in the various terminologies, methodologies, and tools that can be utilized in conjunction with threat intelligence. If analysts can utilize this data, they will be in a better position to take proactive security measures and, in the event of a security incident, be more efficient in their response.

In this chapter’s discussion of cyber threat intelligence, the following key topics will be discussed:

  • Threat intelligence...
