CSPM (Cloud Security Posture Management)
Definition
CSPM is a category of security tools that automatically detect and remediate misconfigurations in cloud environments. Misconfigurations are the leading cause of cloud security incidents.
Cloud Security Posture Management (CSPM) is a category of security tools that automatically detect and remediate misconfigurations, compliance violations and security risks in cloud environments. According to Gartner, through 2025 99% of all cloud-related security incidents will result from customer misconfigurations, making CSPM one of the most critical cloud security tools.
How does CSPM work?
CSPM tools connect to cloud environments (AWS, Azure, Google Cloud) via APIs and continuously scan all cloud resources for deviations from security standards. They detect: publicly accessible storage buckets, overly permissive IAM roles, missing encryption on databases and storage, insecure network rules, disabled logging, and resources non-compliant with CIS Benchmarks, NIST and ISO 27017.
CSPM within the broader cloud security landscape
CSPM is part of a broader CNAPP. Other components include CWPP for runtime protection, CIEM for identity entitlements, and container/Kubernetes security.
Impact on organisations
The speed of cloud adoption leads to configuration drift and misconfigurations discovered only after incidents. CSPM provides continuous visibility and proactive protection. NIS2 requires adequate IT infrastructure security including cloud environments.
Protection
Implement CSPM as the first step in cloud security. Integrate CSPM with SIEM for centralised overview. Automate remediation of critical misconfigurations where possible.
