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.

Forensic platforms

Over the past 15 years, there has been an increase in the power of disk forensics platforms. For the incident response analyst, there are options as to what type of platform can be leveraged to examine disk drives. Often, the limiting factor in utilizing these platforms is the cost of more robust systems, when a lower-cost alternative will be just as effective for an incident response team.

Several factors should be addressed when examining software for disk analysis. First, has the platform been tested? Several organizations test platforms for efficacy, such as the National Institute of Standards and Technology Computer Forensic Tools Testing Program (https://www.cftt.nist.gov/). Second, the tool’s use in criminal and civil proceedings must be examined. There is no single court-accepted standard, but tools should conform to the rules of evidence. The use of a platform that has not been tested or does not conform to the rules of evidence may lead to the...
