To ensure that only hosts on VNET1 can access the slcnage42150372 storage account and that access occurs over the Azure backbone network, you can use  Azure Private Endpoints . This method secures the connection by assigning a private IP address from your virtual network to the storage account, ensuring that traffic does not traverse the public internet.

Step-by-Step Solution

Step 1: Create a Private Endpoint for the Storage Account

Navigate to the Azure Portal .

Search for “Storage accounts”  and select the slcnage42150372 storage account.

In the storage account blade , select  “Networking”  under the “Security + networking” section.

Under “Private endpoint connections” , click on  “Add private endpoint” .

Enter the following details :

Name : Enter a name for the private endpoint (e.g., PrivateEndpoint-VNET1).

Region : Select the same region as your virtual network (VNET1).

Click on “Next: Resource” .

Step 2: Configure the Resource

Select “Target sub-resource” : Choose the storage service you want to connect to (e.g., blob, file, queue, table).

Click on “Next: Virtual network” .

Step 3: Select the Virtual Network and Subnet

Select the virtual n etwork : Choose VNET1.

Select the subnet : Choose the appropriate subnet within VNET1.

Click on “Next: Configuration” .

Step 4: Configure DNS Integration (Optional)

Configure DNS settings  if needed to ensure proper name resolution within your virtual network.

Click on “Next: Tags” , add any tags if necessary, and then click on  “Review + create” .

Review your settings  and click on  “Create” .

Step 5: Restrict Public Network Access

Navigate back to the storage account .

Select “Networking”  under the “Security + networking” section.

Under “Firewalls and virtual networks” , select  “Selected networks” .

Ensure that only VNET1 is listed  under the virtual networks section.

Click on “Save” .

Explanation

Private Endpoints : These provide secure connectivity to Azure services by assigning a private IP address from your VNet to the service, ensuring that traffic stays wit hin the Azure backbone ne twork 1 2 .

Firewall and Virtual Networks : Configuring the storage account to allow access only from selected networks (VNET1) ensures that no other network can access the s torage account 3 .

By following these steps, you can ensure that only hosts on VNET1 can access the slcnage42150372 storage account, and that all access occurs over the secure Azure backbone network.

To prevent all Azure hosts outside of subnet1-2 from connecting to TCP port 5585 on hosts within subnet 1-2, you can use a  Network Security Group (NSG) . This solution is straightforward and minimizes administrative effort.

Step-by-Step Solution

Step 1: Create a Network Security Group (NSG)

Navigate to the Azure Portal .

Search for “Network security groups”  and select it.

Click on “Create” .

Enter the following details :

Subscription : Select your subscription.

Resource Group : Select an existing resource group or create a new one.

Name : Enter a name for the NSG (e.g., NSG-Subnet1-2).

Region : Select the region w here your virtual network is located.

Click on “Review + create”  and then  “Create” .

Step 2: Create an Inbound Security Rule

Navigate to the newly created NSG .

Select “Inbound security rules”  from the left-hand menu.

Click on “Add”  to create a new rule.

Ent er the following details :

Source : Select  Service Tag .

Source Service Tag : Select  VirtualNetwork .

Source port ranges : Leave as *.

Destination : Select  IP Addresses .

Destination IP addresses/CIDR ranges : Enter the IP range of subnet1-2 (e.g., 10.1.2.0/24).

Destination port ranges : Enter 5585.

Protocol : Select  TCP .

Action : Select  Deny .

Priority : Enter a priority value (e.g., 100).

Name : Enter a name for the rule (e.g., Deny-TCP-5585).

Click on “Add”  to create the rule.

Step 3: Associate the NSG with Subnet1-2

Navigate to the virtual network  that contains subnet1-2.

Select “Subnets”  from the left-hand menu.

Select subnet1-2  from the list of subnets.

Click on “Network security group” .

Select the NSG  you created (NSG-Subnet1-2).

Click on “Save” .

Explanation

Netwo rk Security Group (NSG) : NSGs are used to filter network traffic to and from Azure resources in an Azure virtual network.  They contain security rules tha t allow or deny inbound and outbound traffic based on source and destination IP addresses, port, and pr otocol 1 .

Inbound Security Rule : By creating a rule that denies traffic on TCP port 5585 from any source outside of subnet1-2, you ensure that only hosts within subnet1-2 can connect to this port.

Association with Subnet : Associating the NSG with subnet1-2 ensures that the security rules are applied to all resources within this subnet.

By following these steps, you can effectively prevent all Azure hosts outside of subnet1-2 from connecting to TCP port 5585 on hosts within subnet1-2, while minimizing administrative effort.
