Trust Boundaries

Objective​

Define logical and technical separation zones within the lab.

Identified Zones​

  • Public Zone (Internet-exposed services)
  • DMZ / VPS Environment
  • Internal Infrastructure
  • Administrative Access Layer

Rationale​

Trust boundaries are implemented to:

  • Limit impact of service compromise
  • Prevent uncontrolled lateral movement
  • Separate administrative flows from user flows

Enforcement Mechanisms​

  • Firewall rules
  • Network segmentation (VLANs)
  • Bastion-controlled access
