Implement secure endpoints (private and public)

Azure Virtual Network (VNet)

Azure Virtual Network (VNet) provides a private network infrastructure for your Azure resources. By creating a VNet, you can isolate your resources and control inbound and outbound traffic. This helps in implementing secure private endpoints.

To create a VNet, you can use the Azure portal or Azure CLI. Here’s an example of creating a VNet using Azure CLI:

az network vnet create –name MyVNet –resource-group MyResourceGroup \
–location eastus –address-prefixes 10.0.0.0/16 \
–subnet-name MySubnet –subnet-prefixes 10.0.0.0/24

Azure Private Link

Azure Private Link allows you to access Azure services (like Azure Storage, Azure SQL Database, etc.) privately over a VNet. It enables you to establish a private connection between your VNet and the Azure service without exposing your data to the public internet.

Here’s an example of creating a private endpoint for Azure Storage using Azure CLI:

az network private-endpoint create –name MyPrivateEndpoint –resource-group MyResourceGroup \
–vnet-name MyVNet –subnet MySubnet –private-connection-resource-id $STORAGE_ID \
–connection-name MyPrivateConnection –group-id file –connection-sub-resource-name $FILE_SHARE_NAME \
–location eastus

Azure Firewall

Azure Firewall is a managed network security service that protects your Azure VNet. It provides inbound and outbound traffic filtering and can be used to enforce network policies, including securing public endpoints.

To create an Azure Firewall, you can use Azure CLI:

az network firewall create –name MyFirewall –resource-group MyResourceGroup \
–location eastus

Azure Application Gateway

Azure Application Gateway is a web traffic load balancer that enables secure external access to your web applications. It provides features like SSL termination, URL-based routing, and web application firewall (WAF), which adds an extra layer of security to your endpoints.

To create an Azure Application Gateway, you can use Azure CLI:

az network application-gateway create –name MyAppGateway –resource-group MyResourceGroup \
–location eastus –vnet-name MyVNet –subnet MySubnet –capacity 2 –sku Standard_v2 \
–http-settings-cookie-based-affinity Disabled –frontend-port 80 –http-settings-port 80 \
–http-settings-protocol Http –routing-rule-type Basic –backend-pool-name MyBackendPool \
–backend-addresses 10.0.0.4 10.0.0.5 –public-ip-address MyPublicIP

Azure Traffic Manager

Azure Traffic Manager enables you to distribute incoming traffic across multiple endpoints in different regions worldwide. It enhances the availability and performance of your applications, while also providing an additional layer of security.

To configure Azure Traffic Manager, you can use the Azure portal. Here’s an example of setting up traffic routing based on priority:

– Create endpoints for your resources.
– Create a Traffic Manager profile.
– Configure endpoints in the Traffic Manager profile.
– Specify the routing method (Priority).

By following the best practices and utilizing the security features provided by Azure, you can implement secure endpoints for your data engineering solutions. These features provide the necessary tools to protect your sensitive data from unauthorized access and ensure the confidentiality and integrity of your applications.
