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.

Using a centralized approach

The cluster of security tools in many organizations today means that security teams will often have to go into multiple systems and platforms to get essential details about an incident. This can be overwhelming and resource-consuming, especially during active security incidents. Therefore, it would be more ideal for organizations to use a centralized IR approach whereby tools are preconfigured to send data at a central location. Therefore, when the IR team has to act on a security event, they will have all the necessary data points at an easy-to-access location. Some advancements such as applying analytics to the data pulled from multiple tools can accelerate the incident response process. Hence, a centralized IR approach will often lead to a rapid and effective response.

An IR plan might be good in theory yet fail miserably when applied. Therefore, organizations need to test their IR plans thoroughly every once in a while. This will be covered...
