What Actually Happens During a Cloud Security Assessment

"Cloud security assessment" gets used loosely enough that it's worth being specific about what one actually involves — and why the findings that matter most rarely show up on a compliance checklist.

IAM over-permissioning

The single most common finding across AWS, Azure, and Kubernetes environments is roles and service accounts with far more access than they need. A CI/CD pipeline role with full admin. A Lambda function that can read every S3 bucket in the account instead of just the one it needs. This isn't usually malicious — it's what happens when a policy gets written broad "to make it work" during a deadline crunch and never gets tightened afterward. An assessment maps actual usage against granted permissions and flags the gap.

Exposed storage

Public S3 buckets, open Azure Blob containers, and misconfigured storage account access policies remain one of the most common ways sensitive data leaks — not through a sophisticated exploit, but through a default or a checkbox nobody unchecked. This gets checked explicitly, including what's actually stored in anything found open, not just whether it's open.

Misconfiguration-driven privilege escalation

This is where cloud assessments earn their keep beyond a scanner: chaining findings together. A moderately-permissioned IAM user with the ability to modify a Lambda function's execution role, combined with that Lambda having admin access, is a privilege escalation path — even though neither finding alone looks severe. Automated scanners are good at flagging individual misconfigurations; they're much weaker at chaining them into an actual attack path the way a human tester does.

Kubernetes-specific exposure

For clusters, that means checking RBAC bindings against actual need, whether the API server is exposed, pod security standards, network policies between namespaces, and secrets management — the same over-permissioning problem as cloud IAM, just at the cluster layer.

What the deliverable actually looks like

A useful assessment doesn't hand you a scanner printout with hundreds of low-severity items and no prioritization. It traces which findings are chainable into a real path to sensitive data or privileged access, ranks those first, and gives you specific remediation — not "review IAM policies" but which policy, which role, and what to change it to.
