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.

Getting Started with Incident Response

It has become normal for major cybersecurity companies to issue annual threat reports. One of the increasingly common issues that they have noted is an ineffective or delayed Incident Response (IR) protocol. Organizations have become slower in detecting and responding to incidents, which has partially fueled the increased costs, both financially and in terms of data loss, of cyber-attacks. Many organizations either lack practical IR plans or have poor IR management systems. Considering the ever-growing threat of being hacked, organizations should address these challenges promptly, as it raises the organization's awareness about how things can go wrong so that corrective and preventative actions can be taken promptly. That's where this book comes in.

In this chapter, you will be introduced to IR, and how it fits into the world of cybersecurity. We will examine the cybersecurity threat landscape, discuss the types...
