Cloud Misconfiguration
A cloud misconfiguration is a cloud resource setting that creates unintended exposure or weakens an intended security control.
In simple terms
Cloud services have many access, network, logging, and encryption settings. A setting that is convenient for testing may be unsafe for production.
Technical explanation
Examples include overly broad resource policies, exposed management interfaces, disabled logging, and unrestricted network rules. The effective risk depends on surrounding controls and what data or privileges the resource holds.
A setting becomes risky when it grants broader access, exposure, or behavior than intended. Effective review compares deployed resources with approved policy and checks what the setting actually allows.
Examples in practice
A storage bucket meant for internal reports has a policy that permits anonymous reads after a deployment change.
A storage bucket is meant for internal reports but its access policy allows public reads. The team removes that permission, reviews access logs, and scans for other buckets with the same template.
Why it matters
Reviewing effective settings continuously helps catch exposure that appears after infrastructure changes.
