CyberRange Desktop Lab

01 / THE PROBLEM

Problem & objectives

Bring guided cybersecurity courses, practice labs, challenges, and instructor oversight into one local desktop experience.

Local-first defensive cybersecurity training desktop app with guided courses, safe simulations, quizzes, CTF-style challenges, progress tracking, instructor tools, audit logs, and PDF certificates.

02 / THE SYSTEM

Architecture & technology

JavaFX views and controllers call application services. Repositories handle SQLite persistence, while isolated lab engines operate on in-memory models and fictional datasets.

1. JavaFX learning UI
2. Services & safe labs
3. Local SQLite

03 / THE BUILD

Implementation & key features

• Guided defensive-security courses
• Safe simulations and CTF-style challenges
• Progress tracking and instructor tooling
• PDF certificate generation

04 / THE BOUNDARIES

Security & reliability

Design notes and review considerations documented alongside this project:

• Local-first training design
• Safe simulation boundary
• Audit logging for traceability

05 / THE DECISIONS

Challenges & trade-offs

The simulated labs deliberately cannot target real networks, execute host shells, or accept arbitrary cracking targets. This supports safe education while limiting real-world integration.

06 / THE RESULT

Outcome & engineering takeaways

A local training environment with courses, safe simulations, progress tracking, role-aware instructor tools, audit logs, and PDF completion certificates.

The engineering takeaway is to make the system’s capabilities and limits explicit. The repository documents the implementation and its current scope.
