This topic helps you with the decisions you need to make to determine what applications to control and how to control them by comparing Software Restriction Policies (SRP) and AppLocker.Ĭreate a list of apps deployed to each business group This topic for the IT professional lists the design questions, possible answers, and ramifications of the decisions when you plan a deployment of application control policies by using AppLocker within a Windows operating system environment.ĭetermine your application control objectives Understand AppLocker policy design decisions To understand if AppLocker is the correct application control solution for your organization, see Understand AppLocker policy design decisions. For info about these options, see Determine your application control objectives. However, SRP is discussed as a deployment option in conjunction with AppLocker policies. This guide doesn't cover the deployment of application control policies by using Software Restriction Policies (SRP). Through a sequential and iterative process, you can create an AppLocker policy deployment plan for your organization that will address your specific application control requirements by department, organizational unit, or business group. It's intended for security architects, security administrators, and system administrators. This guide provides important designing and planning information for deploying application control policies by using AppLocker. This topic for the IT professional introduces the design and planning steps required to deploy application control policies by using AppLocker. ![]() Learn more about the Windows Defender Application Control feature availability.

To decide whether to apply the policy, I’ll export the current effective Applocker policy and compare it to the XML file. The second step consists in creating the file locally with the XML content thanks to the built-in File DSC resource. Out-File -FilePath ~/Documents\Applocker-pol.xml -Encoding ascii $XmlWriter = New-Object $StringWriterįormat-XML ((Get-AppLockerPolicy -Effective -Xml)) -indent 2 | $StringWriter = New-Object System.IO.StringWriter To solve the indentation issue, I’ve used the Format-XML function written by Jeffrey Snover that you can find on this page.įunction Format-XML ($xml, $indent=2) To configure Applocker, I need first to export the Applocker policy to XML and dump its indented representation to a file. The applocker policy depends on the ‘Application Identity’ service to be enforced.īased on the above light requirements, it seems that built-in DSC resources would actually make it and allow to deploy an Applocker policy locally. XML seems to better way to go although the Applocker policy can be found in the registry under the HKLM\SOFTWARE\Policies\Microsoft\Windows\SrpV2 key. ![]() Let’s also quickly examine the Applocker requirements:Īpplocker rules can be imported from/exported to a XML file using the GUI or using the cmdlets of the built-in Applocker module (it exists since PowerShell version 2.0 on Windows 7). Yes, I know that’s not the most secure Applocker configuration as the example below mixes both a very permissive (default) whitelist and a very specific blacklist.I don’t have anything against these software editors. Do not apply this on your servers/workstations if you don’t understand what Applocker does.I also wondered what it really takes to configure Applocker with PowerShell Desired State Configuration. I was working with Desired State Configuration and wondered why a custom DSC resources hasn’t been published yet for Applocker.īitlocker has already its experimental DSC resource. ![]()
