![]() ![]() ![]() SupportedĬonfiguration Guidance: This feature is not supported to secure this service. Local Authentication Methods for Data Plane Accessĭescription: Local authentications methods supported for data plane access, such as a local username and password. SupportedĬonfiguration Guidance: No additional configurations are required as this is enabled on a default deployment. IM-1: Use centralized identity and authentication system Features Azure AD Authentication Required for Data Plane Accessĭescription: Service supports using Azure AD authentication for data plane access. Identity managementįor more information, see the Microsoft cloud security benchmark: Identity management. Disable Public Network Accessĭescription: Service supports disabling public network access either through using service-level IP ACL filtering rule (not NSG or Azure Firewall) or using a 'Disable Public Network Access' toggle switch. NS-2: Secure cloud services with network controls Features Azure Private Linkĭescription: Service native IP filtering capability for filtering network traffic (not to be confused with NSG or Azure Firewall). ![]() NSGs contain a list of Access Control List (ACL) rules that allow or deny network traffic to your subnet. Protect your subnet from potential threats by restricting access to it with a Network Security Group (NSG). Subnets should be associated with a Network Security Group Reference: Working with NSG access and Azure Bastion Microsoft Defender for Cloud monitoringĪzure Policy built-in definitions - Microsoft.Network: Name (Azure portal) Create NSG rules to restrict your service's open ports (such as preventing management ports from being accessed from untrusted networks). SupportedĬonfiguration Guidance: Use network security groups (NSG) to restrict or monitor traffic by port, protocol, source IP address, or destination IP address. Reference: Tutorial: Deploy Bastion Network Security Group Supportĭescription: Service network traffic respects Network Security Groups rule assignment on its subnets. SupportedĬonfiguration Guidance: Deploy the Azure Bastion into a virtual network with the subnet at least /26 or larger. NS-1: Establish network segmentation boundaries Features Virtual Network Integrationĭescription: Service supports deployment into customer's private Virtual Network (VNet). Service can be deployed into customer's virtual networkįor more information, see the Microsoft cloud security benchmark: Network security. The security profile summarizes high-impact behaviors of Azure Bastion, which may result in increased security considerations. To see how Azure Bastion completely maps to the Microsoft cloud security benchmark, see the full Azure Bastion security baseline mapping file. Please do not forget to "Accept the answer" wherever the information provided helps you to help others in the community.Features not applicable to Azure Bastion have been excluded. Omitting any of the following rules in your NSG will block your Azure Bastion resource from receiving necessary updates in the future and therefore open your resource to future security vulnerabilities.Īzure Bastion opens the RDP/SSH connection to your Azure virtual machine using private IP. Because Azure Bastion connects to your virtual machines over private IP, you can configure your NSGs to allow RDP/SSH from Azure Bastion.īut, if you choose to use an NSG with your Azure Bastion resource, you must create all the following ingress and egress traffic rules. You don't need to apply any NSGs to the Azure Bastion subnet. Azure Bastion is a fully managed platform PaaS service from Azure that is hardened internally to provide you secure RDP/SSH connectivity.
