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. By the end of this book, you’ll have a deep understanding of how to employ PowerShell from both a red and blue team perspective.

Summary

In this chapter, you have learned what language modes are and how they differ from JEA. You have also learned what JEA is and how to set it up.

You now know which parameters you can use to create your own customized JEA role capability and session configuration files (or at least where to go in the book to look for them) and how to register and deploy your JEA endpoints.

Following the examples from this book’s GitHub repository, you have managed to create and explore your own JEA sessions, and you have been provided with an option on how to create a simple first configuration out of your own environment, using JEAnalyzer. Of course, you will still need to fine-tune your configuration, but the first step is done easily.

You have explored how to interpret logging files to correlate JEA sessions over different event logs and what kinds of risks to look out for when creating your JEA configurations.

JEA is a great step to define which commands can be executed...
