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.

Prevention is a key part of a security program and is usually integrated into the protect phase of the National Institute of Standards and Technology (NIST) Cybersecurity Framework. NIST also mentions prevention as being part of the preparation phase of the incident response process. Indeed, being able to prevent a breach is always better than detecting an intruder later on. There are multiple approaches to breach or intrusion prevention.

One important thing we've noticed after several years of incident response practice is that even if the initial access methods vary, common pitfalls stand out in the majority of companies. Here are some of them at the different layers of security.

People: Security awareness does not exist or is too high level or too partial (lack of pragmatism), or people are bored by security measures and so they live their everyday lives without taking care or considering cybersecurity risks.

Processes: No processes are in place to correctly...
