Cloud Security Audit and Protection

3 TB of Customer Data Leaked Through Public S3 Bucket

An e-commerce company received a €1.2 million GDPR fine. An administrator accidentally set an S3 bucket as publicly accessible. 3 TB of customer data (PII, payment cards) was accessible to anyone for 8 months. Attacker bots found it in 3 days.

Without cloud security audit:

• Public buckets, databases, snapshots - data accessible to anyone
• Excessive IAM permissions - every admin has full access
• No data encryption at rest and in transit
• 65% of cloud breaches are misconfiguration, not exploits

CSPM Finds Obvious Errors, Experts Find the Rest

CSPM tools automatically scan thousands of resources. But some errors (overprivileged IAM, broken access control) require expertise. We combine both approaches.

What you get:

• Inventory of all cloud resources (multi-account/subscription/project)
• CSPM scan according to CIS Benchmarks for AWS/Azure/GCP
• Manual review of IAM policies, network security groups, encryption
• List of misconfigurations with severity (Critical, High, Medium, Low)
• Remediation guide with specific AWS CLI/Azure CLI/gcloud commands
• Terraform/CloudFormation for automating fixes where possible
• Cost optimization - unused resources that can be disabled

Who Is It For?

This service is for you if:

• You use AWS/Azure/GCP and want to check if configuration is secure
• You experienced a cloud incident and want to find all gaps
• You must meet compliance (NIS2, ISO 27001, SOC 2, PCI DSS)
• You’re taking over a cloud environment from another team
• You’re planning cloud migration and want to start from secure baseline

What We Check in Each Cloud

AWS Security Best Practices

IAM:

• Root account not used, MFA enabled
• Least privilege policies (not AmazonAdministratorAccess for everyone)
• Access keys rotation, unused credentials disabled
• IAM roles instead of long-term credentials

S3:

• Public access blocked at account and bucket level
• Encryption at rest (SSE-S3/SSE-KMS)
• Versioning enabled for critical data
• Access logging enabled

VPC/Network:

• Security groups - least privilege rules
• NACLs not open to 0.0.0.0/0
• Flow logs enabled
• PrivateLink instead of public endpoints

Logging & Monitoring:

• CloudTrail enabled in all regions
• GuardDuty enabled
• Config rules for compliance
• SNS alerts for critical events

Azure Security Best Practices

Identity:

• MFA for all users
• Conditional Access policies
• Privileged Identity Management for admins
• Managed Identities instead of service principals

Storage:

• Public access disabled
• Encryption at rest (CMK preferred)
• Soft delete enabled
• Advanced Threat Protection

Network:

• NSG rules - least privilege
• Azure Firewall/NVA for centralized filtering
• Private Endpoints for PaaS
• DDoS Protection Standard

Governance:

• Azure Policy for compliance
• Management Groups structure
• Resource locks on critical resources
• Azure Monitor + Security Center

Google Cloud Platform Best Practices

IAM:

• Primitive roles (Owner, Editor) NOT used
• Service accounts with least privilege
• Workload Identity instead of keys
• Organization policy constraints

Storage:

• Uniform bucket-level access
• CMEK encryption
• VPC Service Controls
• Access logs enabled

Network:

• VPC firewall rules - least privilege
• Private Google Access
• Cloud NAT instead of public IPs
• Packet Mirroring for IDS

Security:

• Security Command Center enabled
• Binary Authorization for GKE
• Secret Manager (no hardcoded credentials)
• Audit logs retention

CSPM Tools We Use

• AWS - AWS Security Hub, Prowler, ScoutSuite
• Azure - Azure Security Center, AzureHunter
• GCP - Security Command Center, Forseti
• Multi-cloud - Prisma Cloud, Wiz, Orca
