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.

Deceptive technology

Deceptive technology allows us to decoy attackers to focus on a trap or decoy in order to detect them and potentially identify what secrets they are after or have in their hands. In the next sections, we focus on open source and free solutions that all companies should deploy.

Honeypots

Honeypots are devices that are created to be deliberately attacked to alert the blue team and to keep evidence of the activity. They must generally look vulnerable but shouldn't provide any real system access to an attacker.

There are various approaches when it comes to honeypots. One of them is to deploy them externally to detect and profile attackers and to catch zero-day based attacks. While it can be a great resource for research and CTI purposes, when it comes to detection, it can be overwhelming for a blue team. On the other hand, managing a device that must look vulnerable but not be exploitable at the same time might be a tricky task.

Another approach is...
