Explanation
Here are the steps and explanations for configuring VNET1 to log all events and metrics and query them by using KQL:
* To enable logging for VNET1, you need to create a diagnostic setting that collects the platform metrics and logs from the virtual network and routes them to one or more destinations. You can choose to send the data to a Log Analytics workspace, a storage account, an event hub, or a partner solution1.
* To create a diagnostic setting, you need to go to the Azure portal and select your virtual network. Then select Diagnostic settings under Monitoring and select + Add diagnostic setting1.
* On the Add diagnostic setting page, enter or select the following information:
* Diagnostic setting name: Type a unique name for your diagnostic setting.
* Destination details: Select the destination where you want to send the data. For example, you can select Send to Log Analytics workspace and choose your workspace from the list.
* Log: Select the categories of logs that you want to collect. For VNET1, you can select NetworkSecurityGroupEvent and NetworkSecurityGroupRuleCounter as the log categories2.
* Metric: Select AllMetrics to collect all the platform metrics for VNET12.
* Select Save to create your diagnostic setting1.
* To query the events and metrics from the Azure portal by using KQL, you need to go to the Log Analytics workspace that you selected as the destination. Then select Logs under General and enter your KQL query in the query editor3.
* For example, you can use the following KQL query to get the top 10 network security group events for VNET1 in the last 24 hours:
NetworkSecurityGroupEvent
| where TimeGenerated > ago(24h)
| where ResourceId contains "VNET1"
| summarize count() by EventID
| top 10 by count_
Copy
* Select Run to execute your query and view the results in a table or a chart3.

Explanation:
To prevent all Azure hosts outside of subnet1-2 from connecting to TCP port 5585 on hosts within subnet1-2, 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 where 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.
* Enter 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:
* Network Security Group (NSG): NSGs are used to filter network traffic to and from Azure resources in an Azure virtual network. They contain security rules that allow or deny inbound and outbound traffic based on source and destination IP addresses, port, and protocol1.
* 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.
