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.

Threat Hunting

The release of Mandiant’s APT1 report provided information security professionals with a deep insight into one of the most experienced and prolific threat groups operating. The insight into the Chinese PLA Unit 61398 also provided context around these sophisticated threat actors. The term Advanced Persistent Threat (APT) became part of the information security lexicon. Information security and incident responders now had insight into threats that conducted their activities without detection, and over a significant period.

With the threat that APTs pose, coupled with the average time even moderately sophisticated groups can spend in a target network, organizations have started to move from passive detection and response to a more active approach, to identify potential threats in the network. This practice, called threat hunting, is a proactive process, whereby digital forensics techniques are used to conduct analysis on systems and network components to identify...
