SAN WITH ZERO TRUST ARCHITECTURE
Production-Ready Zero Trust Storage Area Network
The Problem Statement
“Traditional Storage Area Networks grant blanket access once a device authenticates at the perimeter — meaning a single compromised credential exposes the entire storage fabric. This Zero Trust SAN dismantles perimeter trust by continuously scoring every connected device across authentication, health, behaviour, and network reputation dimensions, and dynamically revoking access through real firewall rule injection the moment a device's trust score drops below threshold. It acts as the operational middle ground between theoretical zero-trust frameworks and production-deployable storage security.”
The Architecture Layout
The Zero Trust SAN server runs on Node.js Express with six internal services: Authentication (JWT + device fingerprinting), Health Check (real system checks via OS APIs), Trust Scoring Engine (weighted composite of four factors), Behavioral Monitor (access pattern logging), Anomaly Detector (pattern matching against four attack signatures), and Access Control (iptables/netsh rule injection). All device interactions arrive over HTTPS/TLS. Trust scores (0–100) are recomputed on every significant device event — authentication attempt, health change, anomalous pattern detection — and automatically trigger firewall rule updates below the revocation threshold. A Streamlit Python dashboard polls the SAN server API to display real-time trust scores, session tables, security alerts, and an interactive attack simulation panel for demonstration purposes.
