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.

Integrating CTI with purple teaming

As we saw in Chapter 2, Purple Teaming – a Generic Approach and a New Model, the purple teaming process starts by selecting and preparing TTPs, but during that chapter, we only provided a broad overview.

Based on the knowledge we have gained in this chapter, we will try to apply the CTI process to our purple teaming exercise. As we've seen, we must start by defining the intelligence requirements for our purple teaming exercise.

Now, depending on the type of exercise and the maturity level of our purple teaming program, there are two potential intelligence requirements.

The first one is quite obvious – the CTI must identify, select, and collect information about threat actors and campaigns relevant to our organization. Then, TTPs must be extracted to form an emulation plan so that we are in a position to replay them by performing adversary emulation. This is in order to test our security controls against them.

The second...
