Cloud Security Posture Management (CSPM)

Glossary

## What is Cloud Security Posture Management (CSPM)? Cloud Security Posture Management is a category of security tooling that continuously assesses cloud infrastructure — accounts, storage, networking, identity and access management, and managed services — against security best practices and compliance standards, flagging misconfigurations and drift as they occur. CSPM platforms typically connect via API to cloud provider accounts (AWS, Azure, Google Cloud) and evaluate the live configuration state of resources, rather than scanning source code or container images directly. The output is a stream of findings: a storage bucket with public read access, a security group open to `0.0.0.0/0`, a database without encryption at rest, an IAM policy granting wildcard permissions. CSPM emerged as cloud environments grew too large and too dynamic for manual configuration review, and as **a majority of cloud breaches** came to be traced not to exotic exploits but to avoidable misconfiguration. ## CSPM vs. ASPM: two different layers of the same risk CSPM and [Application Security Posture Management (ASPM)](https://apiiro.com/glossary/application-security-posture-management) are often confused because both use the word "posture," but they sit at different layers of the stack and answer different questions. CSPM asks whether the cloud environment itself is configured securely — permissions, network exposure, encryption, compliance state. ASPM asks whether the application being built and deployed into that environment is secure — insecure code patterns, vulnerable dependencies, exposed secrets, risky architectural changes, and how those risks map to specific services and teams. A cloud account can be perfectly configured according to CSPM while the application running inside it ships a critical injection vulnerability, and conversely an application can be well-written while the infrastructure hosting it is wide open. The two disciplines are complementary rather than redundant, and the relationship between them is worth understanding in more detail than a glossary term allows — see this breakdown of [ASPM vs. CSPM](https://apiiro.com/blog/aspm-vs-cspm/) for how the two layers connect in practice. ## What CSPM tools actually monitor and flag CSPM tools continuously inventory cloud resources and evaluate them against policy sets mapped to frameworks such as CIS Benchmarks, NIST 800-53, PCI DSS, HIPAA, and SOC 2. The core checks fall into a few buckets: **exposure** (public buckets, open security groups, unrestricted network ACLs), **identity and access** (overly broad IAM roles, unused permissions, missing MFA on privileged accounts), **encryption and data protection** (unencrypted volumes, disabled logging, missing key rotation), and **configuration drift**, where a resource that once matched an approved baseline has since changed — through a manual console edit, a misapplied Terraform run, or an out-of-band API call. Drift detection matters because most cloud environments are provisioned through infrastructure as code, and posture can diverge from what's actually declared in a repository. Vendors like Wiz frame CSPM largely around this continuous configuration and compliance monitoring loop, which is a useful reference point for the category's baseline capability. ## Where CSPM falls short without application and code context The structural limitation of CSPM is that it evaluates infrastructure state without knowing anything about the application or the people responsible for it. A CSPM tool can tell a team that a storage bucket is publicly readable, but not which service uses that bucket, what kind of data it holds, whether that exposure was introduced by a recent Terraform pull request, or which engineering team owns the repository behind it. That gap forces security teams into manual triage — cross-referencing cloud account IDs, tags, and Slack threads to figure out who to contact — which is slow and inconsistent at scale. It also means CSPM findings get prioritized by severity heuristics alone, with no sense of whether the underlying resource actually handles [sensitive data](https://apiiro.com/glossary/data-security-posture-management) or sits on a business-critical path, which is exactly the kind of application and data context that separates a genuine risk from a low-priority finding. ## How Apiiro bridges code-level and cloud-level risk for full-stack context [Apiiro](https://apiiro.com/product)'s risk graph correlates cloud posture findings with the code, pull requests, and infrastructure-as-code changes that produced them, along with the identities and pipelines that touched them along the way. Instead of a standalone CSPM alert, a misconfigured resource is traced back to the specific Terraform or [IaC](https://apiiro.com/glossary/iac-security) change and repository that introduced it, attributed to the engineer and team that own it, and weighted by the sensitivity of the application and data it's connected to. That deep-code-to-cloud correlation is also how Apiiro fits into broader [CNAPP](https://apiiro.com/glossary/cnapp) strategies: it supplies the design-through-runtime, code-aware context that infrastructure-only posture tools can't generate on their own, turning a generic misconfiguration alert into an owned, prioritized, and traceable fix.

Is CSPM the same thing as CNAPP?

No. CSPM is one capability within a Cloud-Native Application Protection Platform (CNAPP), which also typically bundles cloud workload protection, container and Kubernetes security, IaC scanning, and identity risk. CSPM alone covers configuration and compliance monitoring; CNAPP combines multiple posture and runtime layers into a single platform.

What kinds of cloud misconfigurations does CSPM typically catch?

Public storage buckets, overly permissive security groups and IAM roles, disabled encryption or logging, missing MFA on privileged accounts, and resources that fail compliance benchmarks like CIS or PCI DSS. It also flags configuration drift, where a resource no longer matches its approved baseline.

How does CSPM relate to Infrastructure as Code (IaC) security?

CSPM evaluates live, deployed cloud resources, while IaC security scans the Terraform, CloudFormation, or Pulumi templates before deployment. Used together, they catch misconfigurations both pre-merge and post-deployment, and correlating the two shows whether drift originated in code or was applied manually.

Can CSPM findings be traced back to the code or pull request that caused them?

Standalone CSPM tools generally cannot, since they only see cloud API state, not source repositories. Platforms that correlate cloud posture with code and IaC history — such as Apiiro — can trace a misconfiguration to the specific commit, pull request, and owning team responsible.
