Network Security Analyzer

Inspect IoT network designs, compare STRIDE findings, and test which controls reduce attack paths

A standalone network security analyzer animation with IoT topology presets, defense overlays, STRIDE findings, attack-path visualization, risk scoring, prioritized recommendations, technical notes, and practice prompts.

Network Security Analyzer

Inspect IoT network designs, identify why they are risky, and test which control reduces the most exposure. The score is a teaching model, not a substitute for a real assessment.

Map the network before scoring it

A smart-home style deployment starts with cameras, a gateway, a phone app, and cloud access on a flat network.

Topology, trust boundary, and attack path

The analyzer highlights exposed nodes, insecure links, and the next best breakpoint.

Current finding

The topology view identifies zones and the first trust boundary before scoring individual weaknesses.

risk = identity + crypto + exposure + containment gaps

Control effect

No control overlay is active, so all scenario weaknesses are visible.

Accuracy warning

This is a teaching analyzer. A real assessment needs asset inventory, traffic capture, configuration review, vulnerability data, and threat context.

Start by naming trust boundaries before recommending tools.

A flat network can turn one weak device into a path toward the gateway and cloud credentials.

ScenarioInsecure smart home with cameras, gateway, mobile app, and cloud.

STRIDE focusSpoofing, information disclosure, and elevation of privilege dominate.

Priority fixAdd identity and secure transport before tuning lower-risk items.

Residual riskScore remains high until exposure and segmentation are addressed together.

Analyzer Controls

Select a deployment, apply one defense layer, and choose the analysis lens. The diagram, metrics, STRIDE notes, and recommendation update together.

Network Analyzer Quick Reference

Asset and zone

List devices by function first. A camera, PLC, or medical sensor should not automatically share trust with a gateway or cloud connector.

Secure flow

A flow is stronger when it has device identity, encrypted transport, authorization, and logging at the boundary.

Attack surface

Every reachable service, management port, protocol bridge, and default account increases ways to interact with the system.

Residual risk

Fixes reduce risk; they rarely erase it. Legacy protocols, physical access, supply chain issues, and operations still matter.

Technical Accuracy Notes

OT security

NIST SP 800-82 Rev. 3 frames OT security around segmentation, access control, monitoring, and management of operational constraints.

Zero trust

NIST SP 800-207 describes zero trust as continuously evaluating access rather than trusting location on the network.

STRIDE

Microsoft threat modeling guidance uses STRIDE categories to reason about spoofing, tampering, repudiation, disclosure, denial of service, and privilege elevation.

Model limit

The score is a deterministic classroom heuristic. It does not query CVEs, prove exploitability, or replace a live assessment.

Common Misreads

Encrypted means safe

TLS helps protect transport, but weak device identity, broad authorization, or exposed admin ports can still leave serious risk.

Segmentation is only VLANs

Useful segmentation includes firewall rules, identity-aware access, monitoring, and operational procedures.

Legacy equals impossible

Legacy protocols often need compensating controls such as gateways, VPNs, allowlists, and monitoring.

Score is the goal

The goal is a defensible fix plan. A lower score without clear asset ownership and monitoring is misleading.

Practice Prompts

Smart home

Select Insecure smart home and Attack path. Which device is the easiest entry point?

Industrial

Select Mixed industrial cell and Segmentation. Why does Modbus still need compensating controls?

Clinic

Select Connected clinic and STRIDE. Which categories matter most for patient data?

Defense order

Compare Identity + TLS with Segmentation. Which fix changes the priority recommendation most?
