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.

The incident response process

We can use all the available industry standards, recommendations, and best practices to create your own IR process. The guide that we are going to use as a reference in this chapter is the Computer Security Incident Response (CSIR) publication, SP 800-61R2, from NIST.

Regardless of what you select to use as a reference, make sure to adapt it to your own business requirements.

Most of the time in security, the concept of "one size fits all" doesn't apply; the intent is always to leverage well-known standards and best practices and apply them to your own context. It is important to retain the flexibility to accommodate your business needs in order to provide a better experience when operationalizing it.
