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.

Introducing CTI

Defining CTI in one chapter is a complex task. Nevertheless, we will try to define what it is and cover the basics needed to understand how it can benefit purple teaming assessments.

CTI was born within military contexts many decades (or, arguably, even centuries) ago. As is often the case in cybersecurity, military concepts are leveraged to improve cyber defense practices. CTI is a good example of such a concept, but just like other military concepts, it has taken time to mature and be correctly applied within organizations.

We will start by dispelling a misconception that developed in the cybersecurity industry due to security vendors and poor marketing campaigns. An IoC is not equal to CTI. Indeed, too many security vendors tried to make organizations think they needed a huge number of IoCs in order to perform CTI. This misconception has become less common as the cybersecurity industry has matured.

Indeed, CTI is way more than just a bunch of indicators...
