Building Cloud Security Posture Management

When to Use

• When an organization lacks visibility into cloud misconfigurations across multiple accounts and providers
• When compliance requirements demand continuous posture monitoring against CIS, NIST, or SOC 2 frameworks
• When security teams need to prioritize which misconfigurations to remediate based on actual risk
• When migrating workloads to the cloud and establishing security baselines before production deployment
• When integrating cloud posture findings into an existing SOC or SIEM platform

Do not use for runtime threat detection (see detecting-cloud-threats-with-guardduty), for application-level vulnerability scanning (see securing-serverless-functions), or for network traffic analysis (see implementing-cloud-network-segmentation).

Prerequisites

• Cloud accounts across target providers (AWS, Azure, GCP) with read-only API access for CSPM tools
• Defined compliance framework requirements (CIS Benchmarks, NIST 800-53, PCI-DSS, SOC 2)
• SIEM or ticketing system for finding ingestion and workflow management
• Budget allocation for commercial CSPM tooling or engineering capacity for native tool integration

Workflow

Step 1: Assess Current Cloud Estate and Risk Appetite

Inventory all cloud accounts, subscriptions, and projects. Classify them by data sensitivity, regulatory requirements, and business criticality to determine CSPM coverage scope.

Cloud Estate Inventory:
+----------------+----------+------------+--------------------+------------------+
| Provider       | Accounts | Workloads  | Data Classification| Compliance Needs |
+----------------+----------+------------+--------------------+------------------+
| AWS            | 45       | Production | Confidential       | PCI-DSS, SOC 2   |
| AWS            | 12       | Dev/Test   | Internal           | SOC 2            |
| Azure          | 8        | Production | Restricted (PII)   | GDPR, SOC 2      |
| GCP            | 3        | Analytics  | Confidential       | SOC 2            |
