Export NSG rules to CSV

Jump to


    Network Security Groups (NSG) play a critical role in managing and securing network traffic within Azure, but managing these rules solely within the Azure portal can be limiting. Exporting NSG rules to a CSV file not only facilitates the migration of rules between classic and Azure Resource Manager (ARM) models, but it also empowers administrators to manage, document, and analyze these rules in a flexible and familiar spreadsheet environment. On this page, we'll delve into the essence of NSG rules, demonstrate the process of exporting NSG rules to a CSV file, explore the practical use cases for such exports, introduce an alternative method using Sourcetable for improved organization, and provide a Q&A section to help clarify any uncertainties about exporting NSG rules to CSV.

    Understanding NSG Rules

    NSG rules constitute a critical component within Azure's networking infrastructure, designed to filter network traffic between Azure resources in an Azure virtual network. As a type of service, network security groups (NSGs) contain a collection of security rules that determine the flow of inbound and outbound network traffic to various types of Azure resources. Each rule within an NSG defines specific properties such as name, priority, source and destination, port, protocol, and the direction of traffic it impacts, alongside the action it enforcesā€”either to allow or deny the traffic.

    From a data perspective, the security rules within an NSG detail the criteria for traffic filtration, including source and destination IP addresses, ports, and the protocols used. These rules are processed in order of priority, and NSGs can accommodate as many rules as needed, within the limits of the Azure subscription. NSGs support the specification of individual IP addresses, ranges, service tags, or application security groups in their rules. Additionally, augmented security rules present in the Resource Manager deployment model simplify the rule creation process by allowing the combination of multiple ports and IP addresses into a single rule, making them easier to understand and maintain.

    Furthermore, the NSG rules software tool, an integral part of Azure Network Watcher, aids in comprehending and debugging the network traffic that is allowed or denied within an Azure virtual network. This tool provides detailed insights and can simulate specific network flows based on the source and destination information, indicating whether the simulated flow is allowed or denied and detailing the pertinent security rule responsible for the decision.

    How to Export NSG Rules to a CSV File

    Using PowerShell Command

    To export classic Network Security Group (NSG) rules to a CSV file, you must have co-administrator access at the subscription level due to the requirement to access classic resources. The PowerShell command to perform this export is:

    Using a Custom Script

    An alternative to the PowerShell command is to employ a custom script. This method can be used to export NSG rules, offering flexibility in handling the export process.

    Migrating NSG via Disassociation

    Another method involves disassociating the NSG and then using the Move-AzureNetworkSecurityGroup command to migrate the NSG, which can be part of the process of exporting NSG rules to CSV.

    Frequently Asked Questions

    How can I export NSG rules from a classic deployment to a CSV file?

    To export NSG rules from a classic deployment to a CSV file, use the command 'Get-AzureNetworkSecurityGroup -Name "Group" -Detailed).Rules | Export-Csv -Path C:\NSG01.csv -NoTypeInformation', replacing "Group" with the name of your network security group.

    What permissions are required to use the 'Get-AzureNetworkSecurityGroup' command?

    The 'Get-AzureNetworkSecurityGroup' command requires detailed permissions to use, and the user must be a co-administrator to access classic resources at the subscription level.

    Why do people export NSG rules to CSV files?

    People export NSG rules to CSV files so they can have a record of the rules and potentially import them into an ARM NSG.

    Can I import rules directly from a classic deployment NSG into an ARM NSG?

    It is not supported to import the rules from the classic deployment directly into an ARM NSG. Rules need to be manually inputted into the ARM NSG.

    How do I specify that I want to export the rules when using the 'Get-AzureNetworkSecurityGroup' command?

    To specify that you want to export the rules when using the 'Get-AzureNetworkSecurityGroup' command, you must use the '-Detailed' flag.


    To efficiently export Network Security Group (NSG) rules to a CSV file, administrators can utilize the PowerShell command 'Get-AzureNetworkSecurityGroup' coupled with the '-Detailed' flag to retrieve a comprehensive list of rules. After obtaining the detailed rules, the 'Export-Csv' command is used to save the information into a CSV file format. It is essential to note that to perform this operation for classic NSG rules, one must have co-administrator privileges. While exporting to CSV is a viable option, a more streamlined approach involves using Sourcetable, which allows you to directly import your data into a spreadsheet.
