![]() ![]() Open remote management ports are exposing your VM to a high level of risk from Internet-based attacks. ![]() Management ports should be closed on your virtual machines IP forwarding is rarely required (e.g., when using the VM as a network virtual appliance), and therefore, this should be reviewed by the network security team. IP Forwarding on your virtual machine should be disabledĮnabling IP forwarding on a virtual machine's NIC allows the machine to receive traffic addressed to other destinations. Learn more about controlling traffic with NSGs at Protect your virtual machines from potential threats by restricting access to them with network security groups (NSG). Internet-facing virtual machines should be protected with network security groups Alerts related to this control may require a Microsoft Defender plan for the related services.Īzure Policy built-in definitions - Microsoft.ClassicCompute: Name (Azure portal) The Azure Policy definitions related to this control are enabled automatically by Microsoft Defender for Cloud. Microsoft Defender for Cloud monitoring: The Azure Security Benchmark is the default policy initiative for Microsoft Defender for Cloud and is the foundation for Microsoft Defender for Cloud's recommendations. ![]() How to deploy and configure Azure Firewall ![]() How to create an NSG with a Security Config Virtual networks and virtual machines in Azure Ensure that all deployed subnets have a Network Security Group applied with network access controls specific to your applications trusted ports and sources.Īlternatively, if you have a specific use case for a centralized firewall, Azure Firewall can also be used to meet those requirements. Guidance: When you create an Azure virtual machine (VM), you must create a virtual network (VNet) or use an existing VNet and configure the VM with a subnet. 1.1: Protect Azure resources within virtual networks Network Securityįor more information, see the Azure Security Benchmark: Network Security. To see how Linux Virtual Machines completely maps to the Azure Security Benchmark, see the full Linux Virtual Machines security baseline mapping file. Controls not applicable to Linux Virtual Machines, and those for which the global guidance is recommended verbatim, have been excluded. ![]()
