Cloud Misconfigurations: The 60% Problem (IAM, Storage, Keys, Gateways)

More than 60% of cloud security incidents in 2026 trace not to zero-days but to misconfiguration — exposed storage, over-permissive IAM, leaked keys, and weak API gateways. The good news: misconfigs are findable and fixable.

The four that cause most incidents

1. Exposed object storage

Public S3/Blob/GCS buckets remain the classic leak. Find your own before someone else does:

# AWS: list buckets with public access not fully blocked
aws s3api list-buckets --query "Buckets[].Name" --output text
aws s3api get-public-access-block --bucket BUCKET   # all four should be true

2. Over-permissive IAM

Wildcard policies ("Action":"*","Resource":"*") and unused admin keys are privilege-escalation fuel. Enforce least privilege and turn on access analyzers.

3. Leaked keys

Long-lived access keys end up in git, CI logs, and client bundles. Prefer short-lived role-based credentials; scan repos and rotate aggressively.

4. Weak API gateways

Unauthenticated routes, missing rate limits, and gateways that forward to internal services without authz.

A pragmatic fix order

1. Block public access at the account level for storage; allow-list exceptions explicitly.
2. Kill wildcard IAM and unused keys; move to short-lived credentials.
3. Enable cloud-native posture tooling (Security Hub / Defender for Cloud / SCC) and a CSPM.
4. Centralise logging — missing logs is itself a top finding and a DPDP/RBI gap.
