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.

The MITRE ATT&CK framework

Looking back at the Pyramid of Pain discussion in the previous section, we can see at the very top are the TTPs that the adversary uses. Modifying these requires additional resources and time on the adversary’s end. Focusing on TTPs from a threat intelligence and mitigation perspective also provides defenders better protection as detections are not tied to an indicator such as a domain name or IP address, which can be easily modified.

The MITRE Corporation has created the Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK) knowledge base, available at https://attack.mitre.org/. This knowledge base incorporates adversary tradecraft, tactics techniques, and adversary behaviors that run through the various stages of a cyberattack. It was started in September 2013, and, as of the time of writing, is now on its ninth version.

The ATT&CK knowledge base started out focusing on the Windows operating system but, over its lifetime...
