Overview of Azure Create Network Security Group

Creating a network security group (NSG) is a crucial step in ensuring the security of your Azure resources. NSGs act as a virtual firewall, controlling inbound and outbound traffic for Azure virtual machines, subnets, and virtual networks. By defining rules within an NSG, you can allow or deny traffic based on source IP addresses, ports, and protocols.

To create an NSG, follow these steps:

• Navigate to the Azure portal and open the Azure Network Security Groups blade.
• Click on the "+ Add" button to start creating a new NSG.
• Provide a unique name and optional description for the NSG.
• Choose the subscription, resource group, and location for the NSG.
• Define inbound and outbound security rules to allow or deny traffic based on your requirements.
• Review the settings and click on the "Create" button to create the NSG.

Benefits of Azure Network Security Groups

• Enhanced security: NSGs provide an additional layer of security by allowing you to control network traffic to and from your Azure resources.
• Granular access control: With NSGs, you can define specific rules to restrict or allow traffic based on your organization's security policies.
• Integration with other Azure services: NSGs seamlessly integrate with other Azure services such as Azure Virtual Desktop, Azure Bastion, and Azure Firewall.

Key Takeaways - Azure Create Network Security Group
