Hey everyone, welcome to my blog where I share some tips and tricks on network security. Today I want to talk about a new feature that Azure recently announced: network security groups support for private endpoints.
Private endpoints are a way to connect your Azure resources securely to other Azure services or on-premises networks without exposing them to the public internet. They use a private IP address from your virtual network and provide identity-based access control with Azure Active Directory.
Network security groups (NSGs) are a simple and effective way to filter network traffic to and from your Azure resources based on rules that you define. You can use NSGs to allow or deny traffic based on source and destination IP addresses, ports, and protocols.
Until now, NSGs were not supported for private endpoints. This meant that you had to rely on other methods to secure your private connections, such as service tags, firewall rules, or application-level authentication. But now, you can use NSGs to control the traffic to and from your private endpoints as well.
This is a great improvement for network security and flexibility. You can now apply granular rules to your private endpoints and isolate them from unwanted traffic. You can also use NSGs to monitor and audit the network activity of your private endpoints.
To use NSGs for private endpoints, you need to enable the feature in your subscription using Azure PowerShell or CLI. Then you can create or update your NSGs with rules that match the private IP addresses of your private endpoints. You can also use Azure Policy to enforce NSGs for private endpoints across your organization.
For more details on how to use NSGs for private endpoints, check out the official documentation here: https://docs.microsoft.com/en-us/azure/private-link/secure-private-endpoint-with-nsg
I hope you found this post useful and learned something new. Stay tuned for more network security tips and tricks in my next blog post.
