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.

High-level architecture

Deploying and setting up an efficient and secure collection infrastructure that will help us detect and investigate potential security issues and cyber security incidents can be very difficult and time-consuming. To ensure we're going in the right direction, we should start by looking at our infrastructure and our current architecture.

One of the major and most important first steps is to understand and visualize our assets and the links they have with each other. Drawing a good schema is always better than long and inaccurate meetings. Of course, in some cases, a schema is not available, so we will need to gather the right people around the same table during meetings to accurately draw it.

The following diagram shows a simplified architecture schema that comprises multiple virtual local area networks (VLANs), users, demilitarized zones (DMZs), production environments, and servers. All of them are behind firewalls and they can all talk to cloud applications...
