Aggiungere Microsoft Antimalware ai cluster di Azure Service Fabric

Azure Service Fabric usa set di scalabilità di macchine virtuali di Azure per creare i cluster di Service Fabric. Attualmente il modello di set di scalabilità di macchine virtuali usato per la creazione dei cluster di Service Fabric non è abilitato con l'estensione Antimalware. Di conseguenza, Antimalware deve essere abilitato separatamente nei set di scalabilità. Quando lo si abilita nei set di scalabilità, tutti i nodi creati nei set di scalabilità di macchine virtuali ereditano e ottengono automaticamente l'estensione.

L'esempio di codice seguente illustra come abilitare l'estensione Antimalware IaaS usando i cmdlet di PowerShell AzureRmVmss.

# Script to add Microsoft Antimalware extension to VM Scale Set(VMSS) and Service Fabric Cluster(in turn it used VMSS)
# Login to your Azure Resource Manager Account and select the Subscription to use
Login-AzureRmAccount
# Specify your subscription ID
$subscriptionId="SUBSCRIPTION ID HERE"
Select-AzureRmSubscription -SubscriptionId $subscriptionId
# Specify location, resource group, and VM Scaleset for the extension
$location = "LOCATION HERE" # eg., “West US or Southeast Asia” or “Central US”
$resourceGroupName = "RESOURCE GROUP NAME HERE"
$vmScaleSetName = "YOUR VM SCALE SET NAME"

# Configuration.JSON configuration file can be customized as per MSDN documentation: https://msdn.microsoft.com/en-us/library/dn771716.aspx
$settingString = ‘{"AntimalwareEnabled": true}’;
# Enable Antimalware with custom policies
# $settingString = ‘{
# "AntimalwareEnabled": true,
# "RealtimeProtectionEnabled": true,
# "ScheduledScanSettings": {
#                             "isEnabled": true,
#                             "day": 0,
#                             "time": 120,
#                             "scanType": "Quick"
#                             },
# "Exclusions": {
#            "Extensions": ".ext1,.ext2",
#                  "Paths":"",

#                               "FallbackOrder”: “”,
#                               "ScheduleDay": 0,
#                               "UpdateInterval": 0,
#                       },
# "CloudProtection": true
# }’;

# retrieve the most recent version number of the extension
$allVersions= (Get-AzureRmVMExtensionImage -Location $location -PublisherName “Microsoft.Azure.Security” -Type “IaaSAntimalware”).Version
$versionString = $allVersions[($allVersions.count)-1].Split(“.”)[0] + “.” + $allVersions[($allVersions.count)-1].Split(“.”)[1]
$VMSS = Get-AzureRmVmss -ResourceGroupName $resourceGroupName -VMScaleSetName $vmScaleSetName

Aggiungere Microsoft Antimalware al servizio cloud di Azure usando il supporto esteso

L'esempio di codice seguente illustra come aggiungere o configurare Microsoft Antimalware al servizio cloud di Azure usando il supporto esteso (CS-ES) tramite i cmdlet di PowerShell.

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

# Update Cloud Service
$cloudService | Update-AzCloudService

Di seguito è riportato un esempio del file XML di configurazione privato

<?xml version="1.0" encoding="utf-8"?>
<AntimalwareConfig
    xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <AntimalwareEnabled>true</AntimalwareEnabled>

    <ScheduledScanSettings isEnabled="true" day="1" time="120" scanType="Full" />
    <Exclusions>
        <Extensions>
            <Extension>.ext1</Extension>
            <Extension>.ext2</Extension>
        </Extensions>
        <Paths>
            <Path>c:\excluded-path-1</Path>
            <Path>c:\excluded-path-2</Path>
        </Paths>

            <Process>excludedproc1.exe</Process>
            <Process>excludedproc2.exe</Process>
        </Processes>

Aggiungere Microsoft Antimalware per i server abilitati per Azure Arc

L'esempio di codice seguente illustra come aggiungere Microsoft Antimalware per i server abilitati per Azure Arc tramite i cmdlet di PowerShell.

#Before using Azure PowerShell to manage VM extensions on your hybrid server managed by Azure Arc-enabled servers, you need to install the Az.ConnectedMachine module. Run the following command on your Azure Arc-enabled server:
#If you have Az.ConnectedMachine installed, please make sure the version is at least 0.4.0
install-module -Name Az.ConnectedMachine
Import-Module -name Az.ConnectedMachine

# specify location, resource group, and VM for the extension
$subscriptionid =" SUBSCRIPTION ID HERE "
$location = " LOCATION HERE " # eg., “Southeast Asia” or “Central US”
$resourceGroupName = " RESOURCE GROUP NAME HERE "
$machineName = "MACHINE NAME HERE "

# Enable Antimalware with default policies
$setting = @{"AntimalwareEnabled"=$true}
# Enable Antimalware with custom policies
$setting2 = @{
"AntimalwareEnabled"=$true;
"RealtimeProtectionEnabled"=$true;
"ScheduledScanSettings"= @{
                            "isEnabled"=$true;
                            "day"=0;
                            "time"=120;
                            "scanType"="Quick"
                            };
"Exclusions"= @{
           "Extensions"=".ext1, .ext2";
                 "Paths"="";
                 "Processes"="sampl1e1.exe, sample2.exe"
            };
"SignatureUpdates"= @{
                              "FileSharesSources"=“”;
                              "FallbackOrder”=“”;
                              "ScheduleDay"=0;
                              "UpdateInterval"=0;
                      };
"CloudProtection"=$true
}
# Will be prompted to login 
Connect-AzAccount 
# Enable Antimalware with the policies
New-AzConnectedMachineExtension -Name "IaaSAntimalware" -ResourceGroupName $resourceGroupName -MachineName $machineName -Location $location -SubscriptionId $subscriptionid -Publisher “Microsoft.Azure.Security” -Settings $setting -ExtensionType “IaaSAntimalware”
