You basically need to employ network engineering level security - very tight firewall rules, use NAT where it’s available (IPv6 removes NAT, which ipv6 apologists will tell you is a good thing - they’re wrong, as it removes per-service level control and moves it out to per-device/per-NIC), and punch very specific holes to grant access where needed.

Prevent north/south traffic entirely, limit east/west traffic heavily
