- Cloud Infrastructure Hardening Across AWS, Azure, and GCP
The foundation of modern IT security lies in properly configured cloud infrastructure. Organizations are rapidly moving beyond basic IAM roles to implement sophisticated zero-trust architectures. For AWS environments, this means leveraging AWS Organizations with SCPs, implementing AWS Config rules for continuous compliance, and utilizing AWS Security Hub for centralized threat detection. Azure professionals must master Azure Policy, Azure Defender, and Microsoft Sentinel for SIEM capabilities. Google Cloud Platform requires expertise in BeyondCorp Enterprise, VPC Service Controls, and Cloud Armor for DDoS protection and WAF capabilities.
Step-by-step guide for implementing a secure AWS multi-account strategy:
1. Initialize AWS Organizations with SCPs
aws organizations create-organization
aws organizations create-policy --1ame "DenyPublicS3" --type SERVICE_CONTROL_POLICY \
--content '{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Deny",
"Action": "s3:PutBucketPublicAccessBlock",
"Resource": "",
"Condition": {
"Bool": {
"aws:SecureTransport": "false"
}
}
}
]
}'
2. Configure AWS Config Aggregator for cross-account compliance
PowerShell for AWS Config Aggregator creation
aws configservice put-configuration-aggregator --configuration-aggregator-1ame "OrgAggregator" `
--account-aggregation-sources "[{\"AccountIds\": [\"123456789012\"], \"AllAwsRegions\": true}]"
3. Deploy Azure Policy for compliance enforcement
{
"properties": {
"displayName": "Audit storage accounts without soft delete",
"policyType": "Custom",
"mode": "Indexed",
"parameters": {},
"policyRule": {
"if": {
"allOf": [
{
"field": "type",
"equals": "Microsoft.Storage/storageAccounts"
},
{
"field": "Microsoft.Storage/storageAccounts/blobServices/default.softDelete.enabled",
"notEquals": "true"
}
]
},
"then": {
