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.

Discovery

When attackers penetrate a network, they usually don't have prior knowledge of the architecture and topology of our networks. Therefore, they must map the network and understand where our crown jewels are to achieve their objectives. This phase usually precedes the lateral movement phase as the attacker needs to figure out where to move. This tactic is also used to better identify the system to which they have access.

In this section, we will look at one technique that's recently been described by public threat intelligence reports: once an attacker has a foothold on a compromised system, they will try to discover other potential lateral movement paths using T1018 – Remote system discovery.

T1018 – Remote system discovery

This technique is widely used by most attackers. Once a host has been compromised, the attacker can usually access local credentials in the form of passwords, hashes, or tokens. From there, attackers are authenticated on...
