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.

Summary

Incident response spans a wide range of disciplines, from legal to scientific. CSIRT members responsible for conducting digital forensics examinations should be very familiar with the legal and technical aspects of digital forensics. In addition, they should be familiar with a wide variety of tools and equipment necessary to acquire, examine, and present data discovered during an examination. The proper application of forensic techniques is critical to provide insight into the chain of events that led to the deployment of the CSIRT to investigate an incident. In this chapter, we initially delved into the various legal aspects of digital forensics, such as the rules of evidence and laws pertaining to cybercrime. Next, we discussed the science of digital forensics, providing an understanding of how techniques should be applied to investigations. To enhance this knowledge, we looked at how these techniques fit into a framework of digital investigations. We then conducted an overview...
