Securing Azure with Microsoft Defender

When to Use

• When deploying cloud workload protection across Azure subscriptions and resource groups
• When establishing a Secure Score baseline and prioritizing security recommendations
• When extending threat protection to multi-cloud environments including AWS and GCP
• When enabling container security for AKS clusters and Azure Container Registry
• When integrating AI workload security with the Data and AI security dashboard

Do not use for AWS-only environments (see implementing-aws-security-hub), for identity provider configuration (see managing-cloud-identity-with-okta), or for network-level firewall rule management (see implementing-cloud-waf-rules).

Prerequisites

• Azure subscription with Security Admin or Contributor role
• Azure Policy initiative for Defender for Cloud enabled at the management group level
• Log Analytics workspace provisioned for security data collection
• Microsoft Defender for Cloud plans licensed (P1 or P2 for server protection)

Workflow

Step 1: Enable Defender for Cloud Plans

Activate Defender plans for each workload type: Servers, Containers, App Service, Storage, Databases, Key Vault, Resource Manager, and DNS. Each plan provides specialized threat detection and vulnerability assessment.

# Enable Defender for Servers Plan 2
az security pricing create --name VirtualMachines --tier Standard --subplan P2

# Enable Defender for Containers
az security pricing create --name Containers --tier Standard

# Enable Defender for Storage with malware scanning
az security pricing create --name StorageAccounts --tier Standard \
  --extensions '[{"name":"OnUploadMalwareScanning","isEnabled":"True",
  "additionalExtensionProperties":{"CapGBPerMonthPerStorageAccount":"5000"}}]'

# Enable Defender for Databases
az security pricing create --name SqlServers --tier Standard
az security pricing create --name CosmosDbs --tier Standard

# Enable Defender for Key Vault
az security pricing create --name KeyVaults --tier Standard

# Verify all enabled plans
az security pricing list --query "[?pricingTier=='Standard'].{Plan:name, Tier:pricingTier, SubPlan:subPlan}" -o table

Step 2: Configure Environment Connectors for Multi-Cloud

Connect AWS accounts and GCP projects to Defender for Cloud for unified security posture management across cloud providers.

# Create AWS connector for CSPM
az security security-connector create \
  --name aws-production-connector \
  --resource-group security-rg \
  --environment-name AWS \
  --hierarchy-identifier "123456789012" \
  --offerings '[{
    "offeringType": "CspmMonitorAws",
    "nativeCloudConnection": {"cloudRoleArn": "arn:aws:iam::123456789012:role/DefenderForCloudRole"}
  }]'

# Create GCP connector
az security security-connector create \
  --name gcp-production-connector \
  --resource-group security-rg \
  --environment-name GCP \
  --hierarchy-identifier "my-gcp-project-id" \
  --offerings '[{"offeringType": "CspmMonitorGcp"}]'
