Azure Synapse Analytics is an integrated analytics service that brings together big data and data warehousing. Securing it involves several steps:
Virtual Network (VNet) service endpoints extend your VNet’s private address space and identity to Azure Synapse. Traffic from your VNet to Synapse Analytics goes directly into the service without traversing the internet.
Example: Suppose you have data that should only be accessible within your organization’s VNet. By enabling a service endpoint for Synapse Analytics, you can ensure data remains within the VNet and does not traverse the public internet.
Private Endpoints create a private IP within your VNet for the Synapse Analytics workspace. This ensures that data traffic is sent privately through the VNet, rather than over the public internet.
Example: You can use a private endpoint to securely connect to your Synapse workspace from on-premises networks or peered VNets.
NSGs can be used to control inbound and outbound traffic to network interfaces (NIC), VMs, and subnets. By default, all inbound traffic to Synapse is blocked. You can customize NSG rules to allow traffic from specific sources.
Example: Create an NSG rule that only allows traffic on port 1433 for SQL data warehouse communication coming from your corporate IP range.
The Azure Synapse Analytics firewall lets you define rules that allow traffic from specified IP address ranges, ensuring that only authorized traffic can access your workspace.
Example: You might configure the firewall to only allow connections from the IPs of your corporate office and a set of designated Azure VMs.
Azure Cosmos DB is a globally distributed, multi-model NoSQL database service. To enhance security with network isolation, you can use the following:
These enable you to secure your Azure Cosmos DB account to only a specific VNet, similar to Synapse Analytics.
Example: Protect your Cosmos DB account by only allowing access from your production VNet, thus preventing any other network from accessing your data.
Private endpoints in Cosmos DB provide secure connectivity from your VNet, using a private IP from your VNet address space.
Example: Integrate your Cosmos DB account with your private network to ensure that all traffic between your VMs and Cosmos DB stays on the Microsoft Backbone network, without hitting the public internet.
Cosmos DB allows you to specify a set of IP address ranges that are allowed to access your data. This is an additional measure if your Cosmos DB instances shouldn’t be publicly accessible.
Example: Allow only your corporate outbound IP address range to communicate with your Cosmos DB account.
Similar to Synapse Analytics, you can control access to and from your Azure Cosmos DB account using NSG rules.
Example: Configure NSGs to only allow Cosmos DB traffic from your application servers, and block all other traffic.
To illustrate the differences and similarities in network isolation between Azure Synapse Analytics and Azure Cosmos DB, consider the following table:
Feature | Azure Synapse Analytics | Azure Cosmos DB |
---|---|---|
VNet Service Endpoints | Supported | Supported |
Private Endpoints | Supported | Supported |
Integrated Firewall | Not applicable; use NSGs | Supported (IP Firewall) |
NSGs | Supported | Supported |
Traffic Routing | Internal with Azure backbone | Internal with Azure backbone |
Support for Managed Identities | Supported | Supported |
Encryption of Data in Transit | Supported | Supported |
Network isolation ensures that only trusted sources can access and interact with Azure data services. By properly configuring VNet service endpoints, private endpoints, NSGs, and firewalls, organizations can significantly enhance the security of their Azure Synapse Analytics and Azure Cosmos DB instances.
Keep in mind that enabling network isolation features may require updates to application connection strings and network configurations to ensure proper connectivity. Network changes should be carefully planned and tested to prevent disruptions to your services while improving security.
Answer: A
Explanation: Virtual Network service endpoints provide the ability to secure Azure service resources to only your virtual network, which in turn can be used for Azure Synapse Analytics.
Answer: A
Explanation: Azure Cosmos DB allows you to configure IP firewall rules that specify which IP addresses or IP address ranges are allowed to access your Azure Cosmos DB account.
Answer: B
Explanation: Azure DDoS Protection Standard provides enhanced DDoS mitigation features for Azure services, including Azure Cosmos DB.
Answer: A
Explanation: A Private Endpoint is a network interface that connects you privately and securely to a service powered by Azure Private Link.
Answer: B
Explanation: Enabling a private endpoint for Azure Synapse Analytics does not disable the public endpoint. However, you can configure your network security to not allow traffic through the public endpoint.
Answer: C
Explanation: Network Security Groups (NSGs) are used to filter network traffic to and from Azure resources in an Azure virtual network. They can be used to control access between resources in different subnets.
Answer: B
Explanation: Azure Private Link is not yet supported for all Azure services, as it’s being rolled out incrementally. You need to check the current status for specific services.
Answer: B
Explanation: Virtual Network Service Endpoints enable you to secure Azure Synapse Analytics so that only your virtual network can communicate with it.
Answer: A
Explanation: Azure Defender provides an additional layer of security intelligence that detects unusual and potentially harmful attempts to access or exploit databases.
Answer: A
Explanation: In the context of security, setting the default consistency level in Azure Cosmos DB is not a direct security feature. The default consistency level affects data accuracy and performance but not specific security threats like unauthorized data access or SQL injection attacks.
A Private Endpoint is a network interface that connects an Azure Cosmos DB account to a virtual network (VNet) through a private IP address.
Private Endpoint ensures that traffic between the Azure Cosmos DB and the client is sent over the private IP address and remains in the Azure network, which provides secure communication.
You can configure a Private Endpoint for Azure Cosmos DB through the Azure Portal or Azure CLI.
Managed Private Endpoints provides secure communication between Synapse workspace and managed Azure services, prevents exposure of public IP addresses and provides better network security.
You can configure Managed Private Endpoints in Azure Synapse Analytics by creating a managed private endpoint and configuring it with the Synapse workspace.
VNet Service Endpoint for Azure Cosmos DB enables traffic from a virtual network (VNet) to be directed to the Cosmos DB service over a private endpoint.
Private Endpoint is used to connect an Azure Cosmos DB account to a VNet, whereas VNet Service Endpoint allows traffic from a VNet to reach the Azure Cosmos DB service.
You can configure VNet Service Endpoint for Azure Cosmos DB by creating a service endpoint in the virtual network and then configuring Cosmos DB to use that endpoint.
Private Endpoint provides a more secure connection as it keeps traffic between the Azure Cosmos DB and the client inside the Azure network, whereas VNet Service Endpoint allows traffic from a VNet to reach the Azure Cosmos DB service.
The steps to configure Private Endpoint for Azure Cosmos DB includes creating a Private Endpoint connection, configuring a virtual network, and configuring the Azure Cosmos DB account to use the Private Endpoint.
You can test the Private Endpoint connection by running a query from a client machine that is connected to the same virtual network as the Private Endpoint.
You can manage Private Endpoint connections for Azure Cosmos DB through the Azure portal, Azure CLI, or REST API.
VNet Service Endpoint reduces network traffic and provides a secure way to access Azure Cosmos DB service over the Azure backbone network.
You can configure a VNet Service Endpoint for Azure Cosmos DB using Azure Portal by creating a service endpoint in the virtual network and then configuring Cosmos DB to use that endpoint.
You can configure a VNet Service Endpoint for Azure Cosmos DB using Azure PowerShell by creating a service endpoint in the virtual network and then configuring Cosmos DB to use that endpoint.
