Key FeaturesIntroduces industry-proven techniques that improve script efficiency and reliabilityExample-rich guide based on real-world scenariosFacilitates building a script that can fully scan a Windows server and identify componentsBook DescriptionEnterprise 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 systems 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.What you will learnCreate an advanced PowerShell scripting template that provides repeatable code to jumpstart all of your scripting projectsLearn how to securely encrypt and store usernames, passwords, and other sensitive data in PowerShell scripts and answer filesUnderstand how to optimize the performance of scripts to help process large datasets quickly and avoid time-consuming mistakesDevelop a script to scan for non-standard Windows Server configurations and identify service accounts used on Windows ServersGather a large list of data from a Windows server without locally or remotely logging in interactivelyAbout the AuthorBrenton J.W.
