Common Cloud Security Control Gaps

← Back to Insights

Cloud breaches rarely start with a sophisticated exploit. Far more often, they start with something ordinary: a permission that was broader than it needed to be, a storage bucket left open, or a configuration default nobody got around to changing.

The gaps that show up most often

• Over-permissioned identities. Roles and service accounts frequently accumulate far more access than they need, often because it’s easier to grant broad permissions once than to scope them precisely.
• Exposed storage and services. Storage buckets, databases, and management interfaces left reachable from the public internet when they were only ever meant for internal use.
• Inconsistent configuration across environments. Security settings that were applied correctly in production but missed in staging or a newer account.
• Weak logging and monitoring. Cloud environments generate extensive activity logs by default, but if nobody is reviewing them, that visibility doesn’t translate into actual detection.
• Long-lived credentials. Access keys and secrets that are never rotated, and in some cases outlive the employee or project they were created for.

Why cloud security is different from network security

Traditional network security assumes a perimeter — a boundary you can harden and monitor. Cloud environments don’t really have one in the same sense. Identity and configuration become the actual perimeter, which is why a cloud security review looks very different from a traditional network penetration test, and why the two aren’t interchangeable.

A practical starting point

Review identity and access first — it’s usually where the highest-impact gaps live. From there, check what’s actually reachable from outside your organisation versus what’s assumed to be internal-only, and confirm logging is both enabled and being reviewed, not just collected.
