Incident Response in the Age of Cloud

By: Dr. Erdal Ozkaya

Overview of this book

Cybercriminals are always in search of new methods to infiltrate systems. Quickly responding to an incident will help organizations minimize losses, decrease vulnerabilities, and rebuild services and processes. In the wake of the COVID-19 pandemic, with most organizations gravitating towards remote working and cloud computing, this book uses frameworks such as MITRE ATT&CK® and the SANS IR model to assess security risks. The book begins by introducing you to the cybersecurity landscape and explaining why IR matters. You will understand the evolution of IR, current challenges, key metrics, and the composition of an IR team, along with an array of methods and tools used in an effective IR process. You will then learn how to apply these strategies, with discussions on incident alerting, handling, investigation, recovery, and reporting. Further, you will cover governing IR on multiple platforms and sharing cyber threat intelligence and the procedures involved in IR in the cloud. Finally, the book concludes with an “Ask the Experts” chapter wherein industry experts have provided their perspective on diverse topics in the IR sphere. By the end of this book, you should become proficient at building and applying IR strategies pre-emptively and confidently.

Building a Culture of Incident Readiness

Due to the continued evolution of cyber threats, organizations have been forced to adapt their Incident Response (IR) strategies as fast as attackers can change their tactics. There is currently a lot of interest in determining and improving the threat preparedness of organizations. Additionally, there have been changes to the conventional techniques used to improve security teams' preparedness for attacks, including the use of Artificial Intelligence (AI), which is gaining prominence in IR processes regardless of whether they are on-premises, in the cloud, or in a hybrid environment.

This chapter focuses on these new changes regarding IR and explains how organizations can adopt them. In doing so, we'll cover the following topics:

  • Threat hunting
  • Purple teaming
  • Artificial intelligence and incident response
  • IR readiness in the cloud

Building a culture of incident readiness starts with threat...
