Overview of this book

Enterprise PowerShell Scripting Bootcamp explains how to create your own repeatable PowerShell scripting framework. This framework contains script logging methodologies, answer file interactions, and string encryption and decryption strategies. This book focuses on evaluating individual components to identify the system’s function, role, and unique characteristics. To do this, you will leverage built-in CMDlets and Windows Management Instrumentation (WMI) to explore Windows services, Windows processes, Windows features, scheduled tasks, and disk statistics. You will also create custom functions to perform a deep search for specific strings in files and evaluate installed software through executable properties. We will then discuss different scripting techniques to improve the efficiency of scripts. By leveraging several small changes to your code, you can increase the execution performance by over 130%. By the end of this book, you will be able to tie all of the concepts together in a PowerShell-based Windows server scanning script. This discovery script will be able to scan a Windows server to identify a multitude of components.

Summary


In this chapter, you reviewed an overview of the Windows server scanning script. You learned that you need to follow a workflow to implement the script in your environment. You started by developing a script to generate randomized strings to create the encryption passwords, salt, and init. You then encoded the results, in the same script, to further secure the values. After creating the encoded password, salt, and init, you created an encryption script with those values to start encrypting strings. After encrypting strings, you continued to learn about the required answer file for the script. You learned what items you need to include in the answer file to ensure that the Windows server scanning script remains flexible. You then proceeded to explore termination files and how they are used to gracefully stop the scanning script remotely. You created a script to create and remove the terminal file locally as well as with a PSSession. Finally, you developed a script to merge the CSV...
