CyberSim OS

Phase 2.5: Localization, Corporate Branding, and Immersive Login

CyberSim OS is an offline-first, browser-native cybersecurity simulation platform designed for enterprise organizations and end-user learners. Learners enter a convincing fictional enterprise workstation, perform routine workplace activities, investigate ambiguous communications, encounter realistic threats (credential harvesting, malicious attachments) alongside legitimate false flags, receive a multi-axis behavioral after-action assessment, and earn cryptographically verifiable completion certificates (*.cybercert).

Phase 2.5 adds organizational readiness through runtime multilingual localization, configuration-driven corporate branding, an immersive workstation login experience, learner first-name personalization, and cross-locale cryptographic verification.

Key Features

• Immersive CyberSim OS Login: Fictional enterprise workstation login and dynamic network/workplace selection without requesting passwords or sensitive employee credentials.
• Runtime Multilingual & Localization (I18n):
  • CyberSim OS user interface localization with deterministic fallback chain (Selected Locale \to Deployment Default Locale \to English \to [missing: key]).
  • Working demonstration locales: English (en) and Spanish (es).
  • Independent scenario content localization (scenarios/<id>/locales/<lang>.json).
• Configuration-Driven Corporate Branding:
  • Customize organization name, short name, logo, desktop wallpaper, accent color, and service desk name via src/config/deployment.json.
  • Automatic fallback to CyberSim default enterprise theme when branding fields are omitted.
  • Preserves simulation safety boundaries (CyberSim identity remains visible).
• Learner Personalization:
  • First-name input is passed into scenario state (learner.firstName).
  • Safe template interpolation ({{learner.firstName}}, {{learner.name}}) in emails, notifications, alerts, web pages, documents, and certificates with strict HTML entity escaping.
• Scenario-Driven Architecture: Complete simulations are defined through declarative JSON scenario packages without application source code modification.
• Verifiable Cryptographic Certificates:
  • Canonical Web Crypto SHA-256 scenario fingerprinting unaffected by display translations.
  • Portable, structured *.cybercert JSON credential export.
  • Standalone offline certificate validator (verify.html) supporting localized verification.
• 100% Offline-First & Zero Dependencies: Runs directly from any static web server, GitHub Pages, or the bundled launcher.py with zero npm/node/external CDN requirements.

Quick Start

Option 1: Standalone Local Launcher (Python 3)

Run the lightweight local launcher to start the server at http://127.0.0.1:8080:

python launcher.py

Your default web browser will open automatically with the CyberSim OS Login interface.

Option 2: Static Web Server

Serve the src/ directory with any static HTTP server:

cd src
python -m http.server 8000

Open http://127.0.0.1:8000 in your browser.

Deployment Configuration

Deployments are customized via src/config/deployment.json:

{
  "organization": {
    "name": "NexaCore Technologies",
    "shortName": "NexaCore",
    "logo": "",
    "wallpaper": "",
    "accentColor": "#2563eb",
    "supportName": "NexaCore Service Desk"
  },
  "localization": {
    "defaultLocale": "en",
    "enabledLocales": ["en", "es"]
  },
  "scenarios": [
    {
      "id": "nexacore-orientation",
      "path": "scenarios/nexacore-orientation/scenario.json",
      "networkName": "NexaCore Corporate",
      "networkDescription": "Corporate Workplace Network",
      "networkIcon": "corporate",
      "supportedLocales": ["en", "es"]
    },
    {
      "id": "quickstart-example",
      "path": "scenarios/quickstart-example/scenario.json",
      "networkName": "Meridian Health Partners",
      "networkDescription": "Clinical & Administrative Network",
      "networkIcon": "health",
      "supportedLocales": ["en", "es"]
    }
  ]
}

Included Scenarios

Scenario	Description	Supported Languages
NexaCore Orientation (nexacore-orientation)	Full-featured scenario: 5 emails, 3 web pages, 3 documents, 6 scoring categories, credential phishing + malicious attachment threats, 2 false flags.	English (en), Español (es)
Meridian Health Quickstart (quickstart-example)	Minimal scenario: 3 emails, 1 web page, 2 documents, 3 scoring categories, 1 credential phishing threat.	English (en), Español (es)

Scenario Localization & Personalization

Scenarios declare supported languages in scenario.json:

{
  "formatVersion": "1.0",
  "id": "my-scenario",
  "supportedLocales": ["en", "es"],
  "login": {
    "networkName": "My Enterprise",
    "networkDescription": "Corporate Network",
    "networkIcon": "corporate"
  }
}

Scenario translations are placed in locales/<lang>.json (e.g. locales/es.json):

{
  "title": "Título en español",
  "description": "Descripción en español",
  "messages": {
    "email_welcome": {
      "sender": "Nombre del Remitente",
      "subject": "Asunto traducido",
      "body": "Hola {{learner.firstName}},\n\n¡Bienvenido a su turno!"
    }
  }
}
