Welcome to ‘Diving In – An Incident Responder’s Journey,’ a comprehensive resource designed for executives, lawyers, insurance brokers, and anyone eager to enhance their understanding of digital forensics and incident response. This guide delves into the vital field of digital forensic science, which focuses on the collection, analysis, and preservation of digital data. This branch of forensic science plays a crucial role in investigating incidents across various devices, including computers, tablets, smartphones, and network devices.

Digital forensics is essential in the realm of cybersecurity. It is frequently employed to address incidents such as ransomware attacks, network intrusions, insider threats, malware incidents, intellectual property theft, cyber espionage, and even cyber terrorism. By thoroughly analyzing the digital evidence that remains after an incident, investigators can uncover the causes and gather pertinent evidence for legal proceedings.

Incident response is a crucial process that aims to address, contain, and mitigate the effects of a cyberattack while preventing further damage. This process encompasses a series of activities that include:

This incident response process requires a coordinated effort from a team of professionals, including IT experts, cybersecurity specialists, digital forensics analysts, and legal advisors. Each of these roles is vital for a successful response to a cyber incident.

In this book, the author discusses the State of Modern Investigative Digital Forensics, including the challenges and considerations faced by contemporary practitioners. Key principles and artifacts that every examiner should understand are covered, alongside foundational knowledge essential for every executive, attorney, and claims manager.

Furthermore, the book explores crucial concepts like The Kroll Intrusion Lifecycle (TM), The Trickle Down Effect, Internet Identity Fusing (IIF), and The Castle Doctrine. The author interrelates these concepts with foundational knowledge about Criminal Groups and Their Methods while providing insights on how to approach Incident Response Planning and Tabletop Exercise Planning.

Three categories of Insider Threats are also highlighted in the book: Malicious Insiders, Negligent Insiders, and Accidental Insiders. Understanding these categories is vital for organizations looking to bolster their cybersecurity defenses.

Moreover, the author discusses emerging threats such as Malware as a Service, Violence as a Service, Swatting as a Service, and Voice Cloning as a Service. These new territories highlight the evolving tactics of threat actors and the importance of staying informed about current trends in cybersecurity.

The final chapters of the book focus on Data Governance, Risk and Compliance, illustrating how these elements intersect with modern Digital Forensics and Incident Response.
