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.

Then, we also dove deeper into two types of security controls: prevention and detection. We saw that detection embeds threat hunting as another type of detective security control. For each of them, we saw guidelines and a management framework to help build maturity around these types of controls. We also saw three key types of rule formats: SIGMA for a SIEM signature, YARA for a file signature, and Snort for a network signature.

Finally, we discussed a short workflow that helps us decide on the type of security controls that should be implemented.

All blue teams', as well as Red teams', activities rely on bigger or smaller infrastructure. The next part of the book is dedicated to building those. We will see the red, blue, and purple teams' infrastructures and components, beginning with...
