+
+# azure_lock
+
+Use the `azure_lock` InSpec audit resource to test properties and configuration of a management lock.
+
+## Azure REST API version, endpoint and http client parameters
+
+This resource interacts with api versions supported by the resource provider.
+The `api_version` can be defined as a resource parameter.
+If not provided, the latest version will be used.
+For more information, refer to [`azure_generic_resource`](azure_generic_resource.md).
+
+Unless defined, `azure_cloud` global endpoint, and default values for the http client will be used.
+For more information, refer to the resource pack [README](../../README.md). 
+
+## Availability
+
+### Installation
+
+This resource is available in the [InSpec Azure resource pack](https://github.com/inspec/inspec-azure). 
+For an example `inspec.yml` file and how to set up your Azure credentials, refer to resource pack [README](../../README.md#Service-Principal).
+
+## Syntax
+
+The management lock resources do not follow the common `resouce_group` and `name` pattern for identification.
+As a result of that, the `resource_id` must be given as a parameter to the `azure_lock` resource.
+The [`azure_locks`](azure_locks.md) resource can be used for gathering the management lock resource ids to be tested within the desired level, such as, subscription, resource group or individual resource.
+```ruby
+describe azure_lock(resource_id: '/{subscriptionId}/resourcegroups/{resourceGroupName}/providers/{resourceProviderNamespace}/{parentResourcePath}/{resourceType}/{resourceName}/providers/Microsoft.Authorization/locks/{lockName}') do
+  it { should exist }
+end
+```
+## Parameters
+
+| Name                                  | Description                                                                       |
+|---------------------------------------|-----------------------------------------------------------------------------------|
+| resource_id                           | The unique resource ID. `/{subscriptionId}/resourcegroups/{resourceGroupName}/providers/{resourceProviderNamespace}/{parentResourcePath}/{resourceType}/{resourceName}/providers/Microsoft.Authorization/locks/{lockName}` |
+
+## Properties
+
+| Property                  | Description |
+|---------------------------|-------------|
+| properties.level          | The level of the lock. Possible values are: `NotSpecified`, `CanNotDelete`, `ReadOnly`. For more see [here](https://docs.microsoft.com/en-us/rest/api/resources/managementlocks/getatresourcelevel#locklevel). |
+| properties.notes          | Notes about the lock. Maximum of 512 characters. |
+| properties.owners         | A list of the owners of the lock with [these](https://docs.microsoft.com/en-us/rest/api/resources/managementlocks/getatresourcelevel#managementlockowner) properties. |
+
+Please note that the properties can vary depending on the `api_version` used for the lookup.
+
+For properties applicable to all resources, such as `type`, `name`, `id`, `properties`, refer to [`azure_generic_resource`](azure_generic_resource.md#properties).
+
+Also, refer to [Azure documentation](https://docs.microsoft.com/en-us/rest/api/resources/managementlocks/getatresourcelevel#managementlockobject) for other properties available. 
+Any attribute in the response may be accessed with the key names separated by dots (`.`), eg. `properties.<attribute>`.
+
+## Examples
+
+### Test If a `ReadOnly` Management Lock Exist in a Specific Resource Group
+```ruby
+azure_locks(resource_group: 'example-group').ids.each do |id|
+  describe azure_lock(resource_id: id) do
+    its('properties.level') { should_not cmp `ReadOnly` }
+  end
+end
+```
+### Test If Management Locks on a Specific Resource Contain a Certain String
+```ruby
+azure_locks(resouce_id: '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/virtualMachines/{vmName}').ids.each do |lock_id|
+  describe azure_lock(resource_id: lock_id) do
+    it('properties.notes') { should include 'contact [email protected]' }
+  end
+end
+```    
+## Matchers

+This InSpec audit resource has the following special matchers. For a full list of available matchers, please visit our [Universal Matchers page](https://www.inspec.io/docs/reference/matchers/).

+# If we expect a resource to always exist

+# azure_locks
+
+Use the `azure_locks` InSpec audit resource to test properties and configuration of all management locks for an Azure resource or any level below it.
+
+## Azure REST API version, endpoint and http client parameters
+
+This resource interacts with api versions supported by the resource provider.
+The `api_version` can be defined as a resource parameter.
+If not provided, the latest version will be used.
+For more information, refer to [`azure_generic_resource`](azure_generic_resource.md).
+
+Unless defined, `azure_cloud` global endpoint, and default values for the http client will be used.
+For more information, refer to the resource pack [README](../../README.md). 
+
+## Availability
+
+### Installation
+
+This resource is available in the [InSpec Azure resource pack](https://github.com/inspec/inspec-azure). 
+For an example `inspec.yml` file and how to set up your Azure credentials, refer to resource pack [README](../../README.md#Service-Principal).
+
+## Syntax
+
+An `azure_locks` resource block returns all management locks, either within a Resource Group (if provided), or within an entire Subscription.
+```ruby
+describe azure_locks do
+  it { should exist }
+end
+```
+or
+```ruby
+describe azure_locks(resource_group: 'my-rg') do
+  it { should exist }
+end
+```
+Also, at resource level test can be done providing the following identifiers: `resource_group`, `resource_name` and `resource_type` or the `resource_id`.
+```ruby
+describe azure_locks(resource_group: 'rg-1', resource_name: 'my-VM', resource_type: 'Microsoft.Compute/virtualMachines') do
+  it { should exist }
+end
+```
+or
+```ruby
+describe azure_locks(resource_id: '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/virtualMachines/{vmName}') do
+  it { should exist }
+end
+```
+## Parameters

+
+Either one of the parameter sets can be provided for a valid query:
+- `resource_id`
+- `resource_group`, `resource_name` and `resource_type`
+- `resource_group`
+- None for a subscription level test.

+### Check If a Specific Management Lock is Present for a Resource
+```ruby
+describe azure_locks(resource_group: 'rg-1', resource_name: 'my-VM', resource_type: 'Microsoft.Compute/virtualMachines') do
+  its('names')  { should include 'production_agents' }
+end
+```
+### Filters the Results to Include Only Those Management Locks which Include the Given Name
+```ruby
+describe azure_locks.where{ name.include?('production') } do
+  it { should exist }
+end
+```
+### Loop through All Virtual Machines to Test If They have Management Locks Defined on
+```ruby
+azure_virtual_machines.ids.each do |id|
+  describe azure_locks(resource_id: id) do
+    it { should exist }
+  end

+### exists
+
+The control will pass if the filter returns at least one result. Use `should_not` if you expect zero matches.
