Public preview: Adaptive network hardening in Azure Security Center
Updated: March 15, 2019
Azure Security Center can now learn the network traffic and connectivity patterns of your Azure workload and provide you with network security group (NSG) rule recommendations for your internet-facing virtual machines. This is called adaptive network hardening, and it's in public preview. It helps you secure connections to and from the public internet (made by workloads running in the public cloud), which are one of the most common attack surfaces.
It can be hard to know which NSG rules should be in place to make sure that Azure workloads are available only to required source ranges. These new recommendations in Security Center help you configure your network access policies and limit your exposure to attacks. Security Center uses machine learning to fully automate this process, including an automated enforcement mechanism. These recommendations also use Microsoft’s extensive threat intelligence reports to make sure that known malicious actors are blocked.
To view these recommendations, in the Security Center portal, select Networking and then Adaptive network hardening.
