Enforce Approved Extensions Are Installed on Azure Compute Virtual Machines
Enforcing that only approved extensions are installed on Azure Compute Virtual Machines is critical for maintaining a secure and controlled environment. This ensures that all installed extensions have been vetted for security and compliance, reducing the risk of vulnerabilities, unauthorized access, and ensuring adherence to organizational policies and security best practices.
This policy pack can help you configure the following settings for Compute virtual machines:
- Stop/Terminate VMs that do not use approved extensions

Credentials
To create a policy pack through Terraform:
- Ensure you have Turbot/Adminpermissions (or higher) in Guardrails
- Create access keys in Guardrails
And then set your credentials:
export TURBOT_WORKSPACE=myworkspace.acme.comexport TURBOT_ACCESS_KEY=acce6ac5-access-key-hereexport TURBOT_SECRET_KEY=a8af61ec-secret-key-herePlease see Turbot Guardrails Provider authentication for additional authentication methods.
Usage
Install Policy Pack
NoteBy default, installed policy packs are not attached to any resources.
Policy packs must be attached to resources in order for their policy settings to take effect.
Clone:
git clone https://github.com/turbot/guardrails-samples.gitcd guardrails-samples/policy_packs/azure/compute/enforce_approved_extensions_are_installed_for_vmsRun the Terraform to create the policy pack in your workspace:
terraform initterraform planThen apply the changes:
terraform applyApply Policy Pack
Log into your Guardrails workspace and attach the policy pack to a resource.
If this policy pack is attached to a Guardrails folder, its policies will be applied to all accounts and resources in that folder. The policy pack can also be attached to multiple resources.
For more information, please see Policy Packs.
Enable Enforcement
TipYou can also update the policy settings in this policy pack directly in the Guardrails console.
Please note your Terraform state file will then become out of sync and the policy settings should then only be managed in the console.
By default, the policies are set to Check in the pack's policy settings. To enable automated enforcements, you can switch these policies settings by adding a comment to the Check setting and removing the comment from one of the listed enforcement options:
resource "turbot_policy_setting" "azure_compute_virtual_machine_approved" {  resource = turbot_policy_pack.main.id  type     = "tmod:@turbot/azure-compute#/policy/types/virtualMachineApproved"  # value    = "Check: Approved"  value    = "Enforce: Stop unapproved"  # value    = "Enforce: Delete unapproved if new"}Then re-apply the changes:
terraform planterraform apply
