Azure Storage Misconfiguration Detection API Reference

Azure CLI - Storage Account Enumeration

# List all storage accounts
az storage account list --query "[].{name:name, rg:resourceGroup, https:enableHttpsTrafficOnly, tls:minimumTlsVersion, publicAccess:allowBlobPublicAccess}" -o table

# Show account details
az storage account show --name mystorageacct --resource-group myrg

# Resource Graph cross-subscription query
az graph query -q "Resources | where type == 'microsoft.storage/storageaccounts' | project name, properties.allowBlobPublicAccess, properties.minimumTlsVersion"

Container Access Level Checks

# List containers with access levels
az storage container list --account-name mystorageacct \
  --query "[].{name:name, access:properties.publicAccess}" -o table

# Set container to private
az storage container set-permission --name mycontainer \
  --account-name mystorageacct --public-access off

Network Rules

# Show network rules
az storage account network-rule list --account-name mystorageacct --resource-group myrg

# Set default action to Deny
az storage account update --name mystorageacct --resource-group myrg \
  --default-action Deny

# Add IP rule
az storage account network-rule add --account-name mystorageacct \
  --resource-group myrg --ip-address 203.0.113.0/24

Security Settings

# Enforce HTTPS only
az storage account update --name mystorageacct -g myrg --https-only true

# Set minimum TLS 1.2
az storage account update --name mystorageacct -g myrg --min-tls-version TLS1_2

# Disable public blob access
az storage account update --name mystorageacct -g myrg --allow-blob-public-access false

# Enable soft delete
az storage blob service-properties delete-policy update \
  --account-name mystorageacct --enable true --days-retained 14

Azure Storage Security Checklist

Check CLI Command Expected
HTTPS only show --query enableHttpsTrafficOnly true
TLS 1.2+ show --query minimumTlsVersion TLS1_2
No public access show --query allowBlobPublicAccess false
Network deny default network-rule list defaultAction: Deny
Logging enabled storage logging show All services enabled
Soft delete on blob service-properties Enabled 7-14 days

Defender for Storage Alerts

Alert Description
