We need to be clear on what PowerShell does and doesn t do when it comes to security, and the best way to do that is to outline some of PowerShell s security goals. First and foremost, PowerShell doesn t apply any additional layers of permissions on anything it touches. That means PowerShell will only enable you to do what you already have permission to do. If you can t create new users in Active Directory by using the graphical console, you won t be able to do so in PowerShell either. PowerShell is simply another means of exercising whatever permissions you already have. PowerShell is also not a way of bypassing any existing permissions. Let s say you want to deploy a script to your users, and you want that script to do something that your users don t normally have permission to do. Well, that script isn t going to work for them. If you want your users to do something, you need to give them permission to do so; PowerShell can only accomplish what the person running a command or script is already permitted to accomplish.

It s beyond the scope of this book, but I do want you to be aware that there are ways to let your users execute a script that runs under credentials other than their own. This is typically accomplished through a technique called script packaging, and it s a feature of some commercial script development environments, such as SAPIEN PrimalScript (www.primaltools.com). After creating a script, you use the packager to bundle the script into an executable (.EXE) file. This isn t compilation in the programming sense of the term: the executable isn t standalone and does require that PowerShell be installed in order to run. You can configure the packager to encrypt alternative credentials into the executable. That way, when someone runs the executable, it launches the packaged script under whatever credentials you specify, rather than the user s own credentials. The packaged credentials aren t 100 percent safe. The package does include the username and password, although most packagers encrypt them pretty well. It s safe to say that most office users won t be able to discover the username and password, but it s completely possible for a skilled encryption expert to decrypt the username and password.

doesn t apply any security beyond the user s existing permissions. We know from past experience, however, that it s easy to trick users into running a script, which might well contain commands that are malicious. So most of PowerShell s security is designed with the goal of preventing users from unintentionally running scripts. The unintentionally part is very important: nothing in PowerShell s security is intended to prevent a determined user from running a script. The idea is only to prevent users from being tricked into running scripts from untrusted sources. PowerShell s security is also not a defense against malware. Once you have malware on your system, that malware can do anything you have permission to do. It might use PowerShell to execute malicious commands, but it might just as easily use any of a dozen other techniques to damage your computer. Once you have malware on your system, you re owned, and PowerShell isn t a second line of defense. That means you ll continue to need anti-malware software to prevent malware from getting onto your system in the first place. This is a hugely important concept that a lot of people miss: just because a piece of malware might utilize PowerShell to do harm doesn t make that malware PowerShell s problem. The malware must be stopped by your antimalware software. Nothing in PowerShell is designed or intended to protect an already-compromised system.
