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.

Incorporating containment strategies

Containment strategies are the actions taken during an incident to limit damage to specific systems or areas of the network. It is critical for organizations to have prepared these in the event of an incident. The rise of ransomware that combines elements of viruses and worms that can quickly spread through an organization highlights the need to rapidly contain an outbreak before it impacts too many systems. What compounds the challenge of containment is that many enterprise IT systems utilize a flat topology, whereby the bulk of systems can communicate with each other. In this type of environment, ransomware and other worms can quickly propagate via legitimate protocols, such as Remote Desktop Services (RDS) or through the Server Message Block (SMB), which were popular during the WannaCry ransomware campaign, which leveraged the EternalBlue vulnerability in the Windows OS SMB installation.
