Enterprise PowerShell Scripting Bootcamp

By: Brenton J.W. Blawat

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.

Chapter 12. Overall Script Workflow, Termination Files, and Merging Data Results

As you are preparing to create the Windows server scanning script, there are multiple components that you will want to create prior to executing the script itself. For example, if you are intending on using encrypted strings, you will need to develop a script to create the randomized password, salt, and init. You will also need another script to perform the encryption of the strings. Due to the multiple scripts that you may need to create, this chapter outlines a recommended script workflow to ensure you have all the components you need to run the scanning script in your environment.

After exploring the workflow, you will proceed to develop a script to create randomized strings. These randomized strings are direct inputs into the encryption script, and are stored in the answer file. You will also learn about how to develop an encryption script to encrypt multiple strings on a loop.
