On our ZenSec blog, we share content on Active Directory Offensive Security and Adversary Simulations — all demonstrated in lab environments.
Recently, we thought it would be great if you could do it freely too and replicate all the things we share on your own!
That’s why we teamed up with
@Kacper Madej
and combined our previous professional blue team experience with offensive security to create a free ebook on building your own offensive and defensive lab:
One that’s flexible, extendable, and structured from the start.
About
There are four things you need to consider when setting up your own offensive & deffensive cybersecurity lab. Whether your are setting it up at home or professionally.
Creating a structured and versatile cybersecurity lab is one of the most effective ways to build practical skills and tackle real-world challenges.
Over the years, we’ve learned that the best labs are not only technically capable but also adaptable to a wide range of scenarios. That’s exactly what the lab we are going to set up is designed to deliver.
Inside this free e-book, you’ll find a full guide on setting up an adversary simulation lab, along with XDR and SIEM integration — so you can test your OpSec, build detections, and check their effectiveness on the fly.
