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.

Language Modes and Just Enough Administration (JEA)

We have learned that PowerShell offers amazing logging and auditing capabilities and explored how to access the local system as well as Active Directory and Azure Active Directory. We also looked at daily red and blue team practitioner tasks. In this part of the book, we are diving deeper into mitigation features and how PowerShell can help you to build a robust and more secure environment.

We will first explore language modes and understand the difference between the Constrained Language mode and Just Enough Administration (JEA). Then, we will dive deep into JEA and explore what is needed to configure your first very own JEA endpoint.

You will learn about the role capability and the session configuration file and learn how to deploy JEA in your environment. If you have the right tools at hand such as JEAnalyzer, creating an initial JEA configuration is not too hard.

Finally, you will understand how to best leverage logging...
