![]() Check it out and let me know if you have questions–or feel free to download and test the script–since it’s on git, you can use it and modify it to your heart’s content, and if you have cool updates, take a pull request and I’ll check it out. So, I went ahead and did a quick video of this. Given that my script is essentially parsing registry.pol, you get all of those additional setting areas for free! Cool. Why? Because all of these additional policy areas store their settings in the same registry.pol file that Administrative Templates does. One thing that I didn’t talk about when I first published this script, was that in addition to the ability to migrate Administrative Template settings from a given existing GPO into a DSC document, the script can also migrate Windows Firewall with Advanced Security, Software Restriction Policy and AppLocker policy. In addition, as I was testing some additional scenarios, I found a bunch of issues around parsing certain kinds of GP settings, so I was able to fix those as well. The key improvements I made were to incorporate Kevin’s advanced function syntax to make the script more PowerShell-friendly. Create Profile > Platform: Windows 10 and later > Profile Type: Templates > Template Name: Custom. You can find the updated script on github. Accessing AppLocker rules via Local Security Policy. ![]() I finally got around to updating this script, with help from our VP of Product Management– Kevin Sullivan. Use of AppLocker is designed to restrict program and script execution by non-administrative users. DifferenceObject (( Get-Content 'C:\windows\temp\polApplocker.xml ')).InnerXmlĭestinationPath = 'C:\windows\temp\polApplocker.If you’ve followed this blog for a while, you know that about a year ago, I described a PowerShell script I wrote that migrates Group Policy Administrative Template settings to PowerShell Desired State Configuration Documents. Feedback In this article Teams allow list with AppLocker Related topics This article explains how to enable the Teams desktop client app with AppLocker application control policies. If you have never created a software restriction policy in the.

Result = (( Get-AppLockerPolicy -Effective -Xml)).InnerXML Here is what the DSC configuration looks like to deploy locally an Applocker policy.ĭependsOn = "XMLPol ", "ApplyLocalApplockerPol " Once the Applocker policy is applied, I’ll start the required service. 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) It is much easier to create rules based on AppLocker Policy files so that. To configure Applocker, I need first to export the Applocker policy to XML and dump its indented representation to a file. the Rule Template field to AppLocker Policy File, as shown in Figure 13.22. 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.
