As Indian enterprises accelerate cloud adoption, security must be built into every layer of the cloud architecture. Misconfigured cloud services are responsible for over 80% of cloud security incidents in India.

Common Cloud Security Mistakes in India

1. Public S3 Buckets / Blob Storage: Leaving storage publicly accessible exposes sensitive data 2. Overpermissioned IAM roles: Admin-level permissions for all services 3. Unencrypted databases: RDS instances without encryption at rest 4. No MFA for root accounts: Root/admin accounts accessible with just a password 5. Missing CloudTrail/Activity logs: No audit trail for security investigations

AWS Security Best Practices

- Enable AWS Organizations with Service Control Policies (SCPs)

  • Enforce MFA on all IAM users and the root account
  • Use IAM roles instead of long-term access keys
  • Enable AWS Config and CloudTrail in all regions
  • Use VPC with private subnets for sensitive workloads
  • Enable Amazon GuardDuty for threat detection

Azure Security Best Practices

- Enable Azure Security Center / Defender for Cloud

  • Use Azure AD Conditional Access policies
  • Enable Azure Monitor and Activity Logs
  • Use Managed Identities instead of service principals with secrets
  • Apply Network Security Groups (NSGs) to all subnets

GCP Security Best Practices

- Enable Cloud Audit Logs for all services

  • Use Workload Identity Federation
  • Enforce Organization Policies
  • Enable Security Command Center
  • Use VPC Service Controls for sensitive data

Compliance Requirements for Cloud in India

Organizations using cloud in India must comply with:

  • CERT-In guidelines for cloud security
  • RBI guidelines for banking data in cloud
  • SEBI cloud guidelines for financial services
  • Data localization requirements under DPDP Act 2023
