What it shows

  • A DMZ isolates publicly exposed services into a monitored perimeter zone.
  • Dual firewalls prevent a compromised edge server from pivoting to LAN assets.
  • Strict firewall rules allow internal traffic out, but block DMZ-initiated ingress.

The takeaway

Buffer internet traffic with a dual-firewall DMZ to stop edge compromises from reaching internal databases.
