Digital Forensics and Incident Response - Second Edition

By: Gerard Johansen

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 second edition will help you perform cutting-edge digital forensic activities and incident response. After focusing on the fundamentals of incident response that are critical to any information security team, you’ll move on to exploring the incident response framework. From understanding its importance to creating a swift and effective response to security incidents, the book will guide you with the help of useful examples. You’ll later get up to speed with digital forensic techniques, from acquiring evidence and examining volatile memory through to hard drive examination and network-based evidence. 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.

Dynamic analysis

Dynamic malware analysis is the detonation of the malware in a controlled environment or malware sandbox. During the execution of the malware, the incident responder is able to see the various processes that are created, the network connections that are established, additional packages that are downloaded, and if the malware performs any actions that allow it to maintain persistence. From this analysis, responders gain a better sense of the IoCs associated with the malware and are better able to identify other systems that have been impacted.

While gaining a sense of the actions malware takes when it executes, dynamic analysis has the advantage of not being as time-intensive as static analysis. Responders often do not need to understand the full depth of complexity of the malware in question, but rather have the ability to identify the IoCs associated with the...
