# Zero Trust Mesh Architecture
**Goal:** Eliminate implicit trust; assume the internal network is already breached.
**Complexity:** Medium
**Prerequisites:** [Memory Manager](../../cognitive/memory-manager.py)

## The Problem
Traditional perimeter security ("castle and moat") fails once an attacker bypasses the firewall. In a system bridging cloud search, memory, and supercomputing, lateral movement is a critical threat.
## Solution Framework: Continuous Validation
1. **Identity Verification:** Enforce Mutual TLS (mTLS) for every API call between `search-agent.py`, `math-engine.py`, and `memory-manager.py`.
2. **Least Privilege:** Compute nodes only receive the exact data subsets required for their specific parallel task.
3. **Micro-Segmentation:** Isolate the Cloud Search container from the Quantum processing containers at the hypervisor level.
4. **Dynamic Ephemeral Tokens:** API tokens expire milliseconds after a computational cycle finishes.
