Overview of this book

Take your cybersecurity skills to the next level with this comprehensive guide to PowerShell security! Whether you’re a red or blue teamer, you’ll gain a deep understanding of PowerShell’s security capabilities and how to use them. After revisiting PowerShell basics and scripting fundamentals, you’ll dive into PowerShell Remoting and remote management technologies. You’ll learn how to configure and analyze Windows event logs and understand the most important event logs and IDs to monitor your environment. You’ll dig deeper into PowerShell’s capabilities to interact with the underlying system, Active Directory and Azure AD. Additionally, you’ll explore Windows internals including APIs and WMI, and how to run PowerShell without powershell.exe. You’ll uncover authentication protocols, enumeration, credential theft, and exploitation, to help mitigate risks in your environment, along with a red and blue team cookbook for day-to-day security tasks. Finally, you’ll delve into mitigations, including Just Enough Administration, AMSI, application control, and code signing, with a focus on configuration, risks, exploitation, bypasses, and best practices.

Simplifying your deployment using JEAnalyzer

When I first learned about JEA, I evangelized it and told everyone how awesome this solution was. Isn’t it awesome restricting the commands your users are allowed to run to exactly to what is needed? Isn’t it amazing to configure virtual accounts and completely avoid passing the hash when using JEA and virtual accounts?

Yes, it is! But when I talked to customers about JEA and how awesome it was, I quickly received the same questions over and over again: How can we find out which commands our users and administrators are using? How can we create those role capability files in the easiest way?

And this was the time when I had the idea for the JEAnalyzer module. After I started the project, my friend Friedrich Weinmann was also very interested in this project, and when I switched jobs and barely worked with customers on other topics than Microsoft Defender for Endpoint, I was glad that he took over what I started and maintained...
