name	building-cloud-security-posture-management
description	This skill guides security architects through designing and implementing a cloud security posture management program that continuously monitors infrastructure configurations across AWS, Azure, and GCP. It covers selecting CSPM tooling such as Wiz, Prisma Cloud, or native services, defining policy baselines, automating drift detection, and integrating posture findings into SOC workflows.

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            |
+----------------+----------+------------+--------------------+------------------+

Step 2: Select and Deploy CSPM Tooling

Evaluate CSPM solutions based on multi-cloud support, policy coverage, agentless scanning, attack path analysis, and integration capabilities.

Native Tools:

• AWS Security Hub CSPM with Config rules
• Microsoft Defender for Cloud CSPM
• Google Security Command Center Premium

Commercial Platforms:

• Wiz: Agentless, graph-based visibility, attack path analysis, highest market mindshare (20.2%)
