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.

Query languages

This section will be dedicated to query languages, which will be used to build step-by-step practical examples of EDR/XDR threat hunting use cases and SIEM queries for threat detections based on statistical anomalies.

Splunk process language

Splunk allows us to directly transform available events but also chain multiple transformations using the pipe (|) sign, allowing the analyst to perform chained treatments of data (for example, getting the required data, then converting it into lowercase, then enriching with the day of the week, then adding a statistics treatment to detect anomalies and so on, all in the same SPL query). We couldn't write this book without showing how powerful and interesting this language could be in terms of detection engineering. To illustrate the possibilities, we chose the following use cases:

  • Detection of lateral movements
  • Detection of persistence mechanisms on an infected machine
