用于为 Azure 启用和配置 Microsoft 反恶意软件的代码示例

本文提供了 PowerShell 代码示例,用于为不同的 Azure 服务启用和配置Microsoft反恶意软件,包括:

  • Azure 资源管理器 VM
  • Azure Service Fabric 群集
  • 使用外延支持的 Azure 云服务
  • 已启用 Azure Arc 的服务器

可以使用这些示例在 Azure 环境中部署和配置Microsoft反恶意软件扩展。

将Microsoft反恶意软件添加到 Azure Service Fabric 群集

Azure Service Fabric 使用 Azure 虚拟机规模集创建 Service Fabric 群集。 目前,用于创建 Service Fabric 群集的虚拟机规模集模板没有启用反恶意软件扩展。 因此,需要在规模集上单独启用 Antimalware。 在规模集上启用它时,在虚拟机规模集下创建的所有节点都会继承并自动获取扩展。

下面的代码示例演示如何使用 AzureRmVmss PowerShell cmdlet 启用 IaaS 反恶意软件扩展。

使用扩展支持将Microsoft反恶意软件添加到 Azure 云服务

下面的代码示例演示如何通过 PowerShell cmdlet 使用扩展支持(CS-ES)将Microsoft反恶意软件添加到 Azure 云服务。

备注

在执行此代码示例之前,必须取消注释变量并提供适当的值。

# Create Antimalware extension object, where file is the AntimalwareSettings
$xmlconfig = [IO.File]::ReadAllText("C:\path\to\file.xml")
$extension =  New-AzCloudServiceExtensionObject  -Name "AntimalwareExtension" -Type "PaaSAntimalware" -Publisher "Microsoft.Azure.Security" -Setting $xmlconfig -TypeHandlerVersion "1.5" -AutoUpgradeMinorVersion $true

# Get existing Cloud Service
$cloudService = Get-AzCloudService -ResourceGroup "ContosOrg" -CloudServiceName "ContosoCS"

# Add Antimalware extension to existing Cloud Service extension object
$cloudService.ExtensionProfile.Extension = $cloudService.ExtensionProfile.Extension + $extension

# Update Cloud Service
$cloudService | Update-AzCloudService
