Tips: Best Practices for The Other Azure Network Resources

In addition to the azurerm_network_security_group, Azure Network has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.

risk-label

azurerm_network_security_group

Ensure to disable RDP port from the Internet

It is better to disable the RDP port from the Internet. RDP access should not be accepted from the Internet (*, 0.0.0.0, /0, internet, any), and consider using the Azure Bastion Service.

risk-label

azurerm_network_security_rule

Ensure to set a more restrictive CIDR range for ingress from the internet

It is better to set a more restrictive CIDR range not to use very broad subnets. If possible, segments should be divided into smaller subnets.

risk-label

azurerm_network_watcher_flow_log

Ensure to enable Retention policy for flow logs and set it to enough duration

It is better to enable a retention policy for flow logs. Flow logs show us all network activity in the cloud environment and support us when we face critical incidents.

Review your Azure Network settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.

Microsoft.Network/applicationSecurityGroups (Azure Resource Manager)

The applicationSecurityGroups in Microsoft.Network can be configured in Azure Resource Manager with the resource name Microsoft.Network/applicationSecurityGroups. The following sections describe how to use the resource and its parameters.
