Purple Team Strategies

By: David Routin, Simon Thoores, Samuel Rossier

Overview of this book

With small to large companies focusing on hardening their security systems, the term "purple team" has gained a lot of traction over the last couple of years. Purple teams represent a group of individuals responsible for securing an organization’s environment using both red team and blue team testing and integration – if you’re ready to join or advance their ranks, then this book is for you. Purple Team Strategies will get you up and running with the exact strategies and techniques used by purple teamers to implement and then maintain a robust environment. You’ll start with planning and prioritizing adversary emulation, and explore concepts around building a purple team infrastructure as well as simulating and defending against the most trendy ATT&CK tactics. You’ll also dive into performing assessments and continuous testing with breach and attack simulations. Once you’ve covered the fundamentals, you'll also learn tips and tricks to improve the overall maturity of your purple teaming capabilities along with measuring success with KPIs and reporting. With the help of real-world use cases and examples, by the end of this book, you'll be able to integrate the best of both sides: red team tactics and blue team security measures.

Chapter 3: Carrying out Adversary Emulation with CTI

In this chapter, we will introduce cyber threat intelligence (CTI). We will learn the different types of intelligence applicable to various cybersecurity threats and identify a range of use cases for CTI. We will also learn how CTI can help us describe a cyberattack, how indicators of compromise (IoCs) should be leveraged, and how everything fits together in the CTI process.

Once we have introduced CTI, we will see how it can be leveraged to provide input for purple teaming assessments to help organizations focus on relevant threats only, thereby prioritizing and maximizing cyber defense efforts.

In this chapter, we will cover the following main topics:

  • Introducing CTI
  • The CTI process
  • The types of CTI and their use cases
  • CTI terminology and key models
  • Integrating CTI with purple teaming
