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

This chapter discussed two major topic areas of memory analysis. First, we covered the available data points and the methodology that can be followed. In addition, several tools, such as Volatility, Volatility Workbench, and Strings, have been explored. In addition to an overview of these tools, several of their features have been explored. This only scratches the surface of the number of features each of these tools has to offer the incident response analyst. These tools, taken in conjunction with a methodology for analyzing system RAM, can give the analyst a powerful tool for determining if a system has been compromised. With malware becoming more advanced, including malware that executes entirely in RAM, analysts must incorporate memory analysis into their capabilities. Marrying these techniques with network evidence collection can provide analysts and their organizations with a powerful tool to identify and remediate an incident.

In the next chapter, we will delve into...
