Short summary
Four AWS misconfigurations regularly cause account breaches and surprise $14K bills: wildcard IAM permissions, unprotected S3 buckets, exposed database ports, and static CI/CD credentials. Each has a straightforward Terraform fix using least-privilege access and temporary credentials. Essential audit checklist for everyone managing AWS infrastructure.
- •Wildcard IAM permissions and exposed S3 buckets let attackers wipe your entire AWS account with a single vulnerability
- •Open database ports and static CI/CD credentials in repos enable database intrusions and credential compromise
- •Each fix is a few lines of Terraform: least-privilege IAM, security group isolation, and OIDC federation for temporary tokens
