11.1Why IAM Testing Is Critical

IAM policy misconfigurations are consistently the top cloud security risk. A single overly permissive policy can grant an attacker access to every resource in your account. A single missing condition key can allow actions from unauthorized networks. Yet most teams treat IAM policies as "set and forget" -- they create them during initial setup and never test them.

Testing IAM policies programmatically means you can catch overly permissive access, missing conditions, and policy drift as part of your CI pipeline, not after a security incident.
