Agile Security Operations

By: Hinne Hettema

Overview of this book

Agile security operations allow organizations to survive cybersecurity incidents, deliver key insights into the security posture of an organization, and operate security as an integral part of development and operations. It is, deep down, how security has always operated at its best. Agile Security Operations will teach you how to implement and operate an agile security operations model in your organization. The book focuses on the culture, staffing, technology, strategy, and tactical aspects of security operations. You'll learn how to establish and build a team and transform your existing team into one that can execute agile security operations. As you progress through the chapters, you’ll be able to improve your understanding of some of the key concepts of security, align operations with the rest of the business, streamline your operations, learn how to report to senior levels in the organization, and acquire funding. By the end of this Agile book, you'll be ready to start implementing agile security operations, using the book as a handy reference.

Principles of cybersecurity operations

Facing up to breaches

Organizations should have a plan for dealing with security incidents. The incident response cycle is a structured template for developing and maintaining such a plan, and it is also a good place to start our discussion of agile security operations.

The incident response cycle, which will form an important aspect of agile security operations, is depicted in the following figure:

Figure 2.1 – The incident response cycle with the identification stage split into detection and analysis steps

The incident response cycle describes a process for handling incidents in several separate steps. Somewhat dependent on the organization, the incident response cycle can take several forms and may involve a somewhat different set of steps.

We will first discuss the background to the incident response cycle. In the following sections, we will briefly discuss the NIST incident response cycle and the SANS incident response cycle.
