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.

Not every incident will dictate the need to obtain an image from a potentially compromised hard drive or other volume. Regardless, incident response analysts should be familiar with, and able to perform, this function when called upon. The evidence that's found on a hard drive may be critical to determining a sequence of events or to obtaining actual files that can aid in determining the root cause of an incident. This is the central reason why responders need to understand the fundamentals of imaging and the tools and processes involved, how to create a stage drive, how to use write blockers, and how to execute any of the imaging techniques we mentioned in this chapter. As with any process that's performed in a forensic discipline, imaging should be conducted in a systematic manner in which all the steps are followed and properly documented. This will ensure...
