Here's a scenario that happens more often than anyone would like to admit: a developer provisions an S3 bucket through Terraform, forgets to set the access control, and deploys it to production. The bucket is now publicly accessible. Customer data sits there, open to anyone who knows the URL.

This isn't a hypothetical. Misconfigured cloud storage has been the root cause of some of the largest data breaches in history. The Capital One breach (100 million customer records) started with a misconfigured web application firewall. Countless others trace back to publicly accessible S3 buckets, open databases, and overly permissive IAM roles.

Infrastructure as Code solved the "works on my machine" problem for infrastructure. IaC security scanning solves the "deploys insecure by default" problem
