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.

Intrusion detection systems

IDSs, or more specifically, network intrusion detection systems (NIDSs) as opposed to host intrusion detection systems (HIDSs), rely on a network functionality called port mirroring or devices such as network taps to analyze duplicated traffic sent on a dedicated switch port. Most of the manageable modern switches offer port mirroring functionality. IDSs are one of the key components a blue team may rely on for network analysis. In large companies, it is not always possible in terms of architecture to send traffic from all switches. In such a situation, the traffic should be mirrored at the company core switch level. As usual, there are commercial and open source solutions. Some solutions, such as Darktrace, offer beautiful user interfaces and are powered by artificial intelligence (AI) or machine learning (ML) engines, and need to learn from existing traffic. As usual, open source alternatives exist, such as Suricata, Snort, and Zeek. These IDSs don&apos...
