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 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.

Endpoint detection and response

Ransomware has arguably been the one key threat that has changed how an incident response is conducted. The speed and widespread impact of such attacks has highlighted the need for tools that provide analysts with a method to search across the entire network infrastructure. This is where endpoint detection and response (EDR) tools come into the picture.

EDR tools grew out of the traditional signature-based antivirus that permeated the industry for nearly two decades. Building on the capability to match hash values and other signatures, EDR tools bring much-needed distributed capabilities to security and incident response teams. There are a variety of commercially available EDR platforms, each with distinctive features, but at a high level, they can generally perform the following functions:

  • Monitor and detect threats on endpoints: This is where EDRs overlap with traditional antivirus. EDR platforms use a combination of signature matching,...
