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 started with a completely new exercise. In the preparation phase, we used the information and the intelligence we gathered from Chapter 10, Purple Teaming the ATT&CK Tactics, to craft and establish a potential threat actor profile (that is, via a simulation plan). This plan was then executed with a specific Atomic Red Team configuration. After that, we went through the identification part of the PEIR process and started reviewing our detection capabilities and highlighting potential gaps in the basket. As a logical reflection, in real organizations where we need to reduce the processing time, we should move on to the second stage of purple team maturity. Thus, we introduced some sources of emulation plans that can be easily imported into Caldera. The two examples that we went through (Scythe and CTID) provided useful resources to help you perform efficiently and continue purple teaming. Finally, we highlighted some of the common issues we may encounter...
