What should you use to prevent traffic from an Azure virtual network from being routed to an?
This deployment option describes how to deploy a scale set of virtual appliances behind the Azure Firewall to provide advanced network protection. Deploying a scale set behind the Azure Load Balancer provides additional layers of availability, which means minimal disruption if a virtual appliance experiences an outage. Show
The following diagram shows an example of the traffic flow for this deployment: IMPORTANT: Internet connectivity notice During the Deploy the Network Security virtual appliance step, the Network Security virtual appliance is configured behind a standard internal load balancer. The placement of this load balancer blocks the outbound internet connectivity by default unless internet connectivity has been explicitly declared. For this deployment, add a NAT gateway to the management subnet to allow outbound connectivity so that your Network Security virtual appliance can communicate with Network Security. This option is configured before the Network Security virtual appliance is deployed. Complete these tasks to set up your environment:
Before you begin
Create a resource groupCreate a resource group if one does not already exist in your environment.
Create the spoke virtual network and workload subnet
Create a Workload virtual machine (optional) Follow these steps if you are creating this environment as a proof of concept or if you do not have an existing workload in your environment.
Backend workloads example If you followed the steps above to create a workload in your Azure environment, the following table provides an example of configuration details for two virtual machine web workloads. Install an HTTP server if you intend to configure backend workloads after they are created.
Create the hub inspection virtual network and subnetsUse the procedure below to manually set up the inspection-VNet (hub) and subnets. You will select all of the subnets when you deploy your Network Security virtual appliance.
Add peering to connect the hub and spoke VNets
Add a NAT gateway to the management subnetAs described in the Internet connectivity notice section, add a NAT gateway associated with the management subnet to your configuration to allow the Network Security virtual appliance to communicate with Network Security. NOTE There is an option to automatically generate a NAT gateway when you deploy the Network Security virtual appliance. Select the option to automatically generate the NAT gateway in the Deploy the Network Security virtual appliance section or use these steps to manually deploy the NAT gateway.
The management subnet can be associated after the NAT gateway is created by clicking the Subnet menu option from the NAT gateway details page. Deploy the Network Security virtual applianceThe Network Security virtual appliance is available from the Azure Marketplace as a public offer. To deploy the Network Security virtual appliance, navigate to Azure Portal → Marketplace → Trend Micro Cloud One™ – Network Security. Manually add virtual appliances to Trend Micro Cloud One if the Azure Marketplace deployment does not properly register the virtual appliance(s) to Network Security. Gather the following information before you begin the deployment:
Note Best practice is to copy and paste the exact names of the resource group, hub-VNet, and subnets.
Configure the Azure FirewallAfter you create and deploy the Azure Firewall, make the following configuration changes. Learn more. Note the Firewall IP information Private and public IPs are assigned automatically after you create the firewall. Note the IP information for future use in the deployment process.
Configure the Firewall rules Configure the AzureFirewall NAT Rule (Ingress) and Network Rule (Egress). Configure the NAT rule
Configure the Network Rule
Configure route tables and rulesAfter the Network Security virtual appliance is deployed, add and configure the route tables and routes to place your virtual appliance in-line and begin inspecting traffic. The firewall rules are applied to the network traffic when it is routed to the firewall as the subnet default gateway. The following information is required to complete this process:
Step 1: Create three route tables
Step 2: Configure the route tables
Step 3: Associate the route tables to the related subnet
What should you use to prevent traffic from an Azure virtual network from being routed to an Azure storage account via the Internet?The Azure storage firewall provides access control for the public endpoint of your storage account. You can also use the firewall to block all access through the public endpoint when using private endpoints.
What should you use to prevent traffic from an Azure virtual network from being routed AZ 900?You can restrict traffic to multiple virtual networks with a single Azure firewall. Azure Firewall is a managed, cloud-based network security service that protects your Azure Virtual Network resources.
How do I stop Azure VM from accessing the Internet?To get started we need to create a new Network Security Group > Type Network Security Group in the Azure search bar. Select Network Security Group. To create a new network Security Group, click on the +Create. Now that we have a new NSG created, Lets go to Outbound Rules and lock down Internet Access for this NSG.
Which of the following can you use to filter traffic to and from an Azure Virtual Network?You can use an Azure network security group to filter network traffic to and from Azure resources in an Azure virtual network. A network security group contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources.
