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.

Summary

In this chapter, we saw that purple teaming is a process that can be applied in different kinds of assessments; nevertheless, we strongly believe that purple teaming is also a mindset that must be incorporated into an organization's culture. Purple teaming exercises help to build human cross-collaboration between red and blue teams. This is exactly what purple teaming enables within an organization – a common and shared objective: improving the organization's security. After all that, does this mean that red teaming exercises don't make sense anymore? Not at all – they do serve a purpose to test responsive capabilities in a realistic scenario where the blue team is not informed, and the red team performs actions with stealth in mind.

In the next chapter, we will introduce CTI and what it implies, as well as defining how it should be leveraged as an input for purple teaming.
