CSPM Mastery: Building Open-Source Cloud Security Posture Management to End Misconfigurations.

Stop Paying for Black-Box Security. Build the Ultimate Open-Source Cloud Security Posture Management (CSPM) System.Cloud misconfigurations - open S3 buckets, wildcards in IAM, and exposed Kubernetes dashboards are the root cause of the most devastating data breaches in modern history. Yet, engineering teams continue to rely on bloated, expensive commercial CSPM tools that flood their Slack channels with false positives and lack true infrastructure context.CSPM Mastery is the definitive engineering blueprint for building a custom, highly effective Cloud Security Posture Management platform using entirely open-source tools. This book takes you beyond the basic scans, teaching you how to build a unified system that connects AWS, Azure, GCP, and Kubernetes into a single, queryable graph to expose real-world attack paths before attackers can exploit them.Inside, you will discover:The Open-Source Ecosystem: Master the deployment and integration of industry-standard tools like Prowler, Checkov, Terrascan, Trivy, and Steampipe.Graph-Based Attack Path Analysis: Use Cartography and Neo4j to model permission relationships and lateral movement, connecting isolated misconfigurations into catastrophic breach scenarios.KSPM (Kubernetes Security Posture): Secure the gaps cloud providers ignore. Implement runtime policy enforcement with OPA and Kyverno, and lock down RBAC and Admission Controllers.Building the Policy Engine: Write high-signal, testable "Policy as Code" using Rego and CEL to eliminate alert fatigue and drop false positives.Automated IaC Remediation: Stop playing whack-a-mole. Generate automated Terraform, CloudFormation, and Pulumi patches that fix the root cause in the repository, not just the symptom in production.Operating at Scale: Map your findings to CIS, SOC 2, and PCI-DSS compliance frameworks while managing API call budgets to ensure your security tooling doesn’t become its own cloud bill problem.REAL-WORLD BREACH DECONSTRUCTIONS (Chapter 4)Learn from the industry's biggest failures. This book deconstructs the exact misconfiguration chains that led to the Capital One, Twitch, and Uber breaches and shows you exactly how a properly tuned open-source CSPM would have stopped them automatically.Take back control of your infrastructure. Shift security left, eliminate misconfigurations, and build a CSPM architecture that your developers will actually respect. Read more
