The CIA Triad

Confidentiality, Integrity, and Availability are the three pillars of information security. Watch each principle break in real time.

Enterprise Data Flow Simulation
Click a simulation button to watch the attack visually unfold.

Asset → Threat → Vulnerability → Risk

Every risk connects an asset, a vulnerability, and a threat. Build the chain step by step.

Attack Chain Visualization
Click "Advance Step" to reveal each element.

Attack Surface

Every exposed entry point increases attack surface. Click each one to inspect.

Company Network Topology
Click any entry point to inspect its exposure level.

Authentication vs Authorization

Authentication proves who you are. Authorization determines what you can access.

Identity Flow Simulation
Choose a user to watch the identity flow.

Multi-Factor Authentication

Toggle MFA on and off. Simulate a stolen password attack to see the difference.

MFA Protection Simulation
MFA: ENABLED
Toggle MFA, then run the stolen password attack.

Firewall Rules

A firewall evaluates every packet against rules. Watch packets get allowed or blocked.

Packet Flow Simulation
Send packets and watch the firewall evaluate rules.

Network Segmentation

Segmentation isolates zones. Watch packets traverse or get blocked.

Network Segmentation Topology
Send traffic between zones.

Security Logging

Every action generates a log event. Watch them flow into the SIEM.

Live Event Generator
ACTIONS
SIEM LOG STREAM
Click actions to generate log events.

SOC Alert Pipeline

Events flow through collection, normalization, correlation, and alert stages.

SOC Pipeline
Generate events and watch them flow through the pipeline.

Incident Response Lifecycle

Step through a real incident from detection to lessons learned.

Incident Timeline: WORKSTATION-101
CURRENT PHASE
Click "Advance" to begin.

Defense in Depth

Multiple layers protect data. Watch an attack attempt traverse each layer.

Layered Defense Simulation
Choose an attack level.

Threat Detection

Compare normal baseline against anomalous behavior.

Traffic Analysis
NORMAL BASELINE
LIVE TRAFFIC
Generate traffic and compare.

Security Investigation

Click events. Watch the topology and evidence panel update.

Investigation Dashboard

EVENT TIMELINE

Risk Matrix

Place scenarios on the matrix. The system calculates risk level.

Interactive Risk Assessment
RISK MATRIX
SCENARIOS
Select a scenario, then click a cell.

Vulnerability Prioritization

Drag vulnerabilities into priority buckets.

Prioritize Vulnerabilities
Drag each vulnerability into the appropriate bucket.

Attack Lifecycle → Defense Telemetry

Watch an attack unfold and see which controls detect it.
