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.

Summary

In this chapter, you learned about the importance of threat intelligence and how it can be used to gain information about current threat actors and their techniques and, in some circumstances, to predict their next steps. You learned why threat intelligence matters and how you can share intelligence for better IR processes. Then, you learned how to leverage threat intelligence from the open source community using free tools as well as commercial tools.

After that, you learned how Microsoft integrates threat intelligence as part of its products and services and how to use Azure Sentinel not only to consume threat intelligence but also to visualize potentially compromised features of your environment based on the threat intelligence acquired. Lastly, you learned about the investigation feature of Azure Sentinel and how this feature can be used by the IR team to find the root cause of a security issue.
