Security Best Practices
Hard Code Secrets: Never directly put the secret into Terraform files.
Sensitive Flag: Use the sensitive flag to hide outputs by setting it to true.
Secure State: State files to be stored securely using S3 with encryption.
This ensures that secrets handling by Terraform is secured.
