A firewall rule should be boring, explicit, and documented. Before a VPS goes into production, review what is open to the internet and why. SSH, HTTP, HTTPS, database ports, admin panels, monitoring agents, and temporary debugging ports should not all be treated the same. A simple review helps: • Which ports are public? • Which ports are internal only? • Which services need IP restrictions? • What temporary access must be removed? Security is easier when the server’s exposure is intentional instead of accidental. Plan VPS deployments with control in mind: https://lnkd.in/dBx_HQDR
