## Critical Findings
### [CRIT-001] SSH Open to World
**File:** `production/core/main.tf:62`
**Resource:** `digitalocean_firewall.app`
**Issue:**
SSH (port 22) is accessible from any IP address.
**Current:**
```hcl
inbound_rule {
protocol = "tcp"
port_range = "22"
source_addresses = ["0.0.0.0/0"]
}
Remediation: Restrict SSH to known IP addresses or VPN CIDR.
inbound_rule {
protocol = "tcp"
port_range = "22"
source_addresses = var.ssh_allowed_ips # ["203.0.113.0/24"]
}
...
## Execution
When invoked:
1. Find all IaC files:
```bash
find . -name "*.tf" -o -name "*.tfvars" -o -name "cloud-init*"
tofu validate 2>&1 || true
