Using Azure DevOps to track changes to Network Security Groups in Azure

I wanted an easy way to keep track of changes made to our NSGs in Azure and through a combination of a few offerings in Azure I settled on what I feel is a pretty good solution. The runbook is on a schedule to run every day and performs the following:
  1. Get the current configuration of the Network Security Group (NSG)
  2. Push the current configuration of the NSG to a DevOps repository
  3. Compare the current configuration against the previous configuration
  4. If there are any changes, send an email

Resources needed:
Azure Automation Runbook
Azure DevOps license (Basic Plan for access to use Repos)
Powershell
Azure Keyvault (for storing the DevOps API key)

Runbook code:

Auto-installing extensions on Firefox using Intune

Image
To build onto my previous blog post concerning ADMX ingestion in Intune to configure Mozilla Firefox settings I'm going to show you how to auto-install extensions in Firefox with Intune. In this example I'm using the uBlock Origin extension as an example. First you'll need to get the URL of the extension. This is different from Chrome where you just need to get the ID of the extension. The easiest way I found to do this is to open Firefox and go to the Extensions Page  at Mozilla and locate the extensions you want to install. Then right-click and copy the link to the "Add to Firefox" button on the extension page. Save the link for later. Now go to the Custom OMA-URI Settings profile in Intune and add a new row. Configure the fields as follows: Name : Extensions_Install OMA-URI (case sensitive):  ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/Extensions_Install Data type (String value)*: <enabled/> <data id="...

Disable DNS over HTTPS in Firefox using Intune

Image
Mozilla makes available admx files (Group Policy settings) which allow you to configure some settings in Firefox using Group Policy.  I'm trying to move away from using Group Policy to manage our endpoints since it requires connectivity to a Domain Controller which in turn depends on a VPN connection for remote computers. Too many dependencies there for my taste and Intune makes it much easier to push out changes with the push of a button. This week I've been trying to use a custom configuration profile in Intune to disable DNS over HTTPS on our Windows endpoints. Some of our IPS functionality uses DNS requests to block access to certain websites and DNS over HTTPS makes it easy to bypass that method of content blocking. Intune offers something they call "ADMX ingestion" which sounds weird and biological but basically it just lets you apply Group Policy like functionality using Intune. Making changes to Chrome was easy using this method because Google has a...

Moving Applocker control from Group Policy to Intune

Image
Lately I've been trying to migrate a lot of GPOs to Intune so that our endpoints don't have to depend on a VPN for updating policy. Applocker was an important one for us since VPNs are flaky and it's important that users be able to run updated software while away from the office network. Chrome once updated its signing certificate and because it auto-updates itself we had users who couldn't launch Chrome until they were able to get connected to the VPN and run a gpupdate. I already had the plumbing in place which allows Admins to upload files to a file share and have them automatically added as whitelisted to the Applocker GPO . Now I just had to move the enforcement of the GPO into Intune. I decided to keep the dependency on our Domain Controllers merging the changes into the Applocker policy since there are some pretty good Powershell commands that take care of that. The GPO for Applocker is still being updated but is only used for Intune to pull from and turn int...
