Network Flow Simulator
Send safe simulated packets through PC, gateway, DNS/router and training server while inspecting addressing, ports and protocol choices.
Learn concepts by manipulating safe simulations, inspecting realistic prepared data, executing browser-safe code and solving defensive challenges.
These Stage 2 labs do not scan public systems or expose an unrestricted shell. Real Nmap execution is available in Stage 3 through the downloadable CyberForge Local Lab Runner on the student PC.
Send safe simulated packets through PC, gateway, DNS/router and training server while inspecting addressing, ports and protocol choices.
Inspect prepared Ethernet, IP, TCP/UDP, DNS and HTTP packet examples layer by layer.
Build GET and POST requests, inspect headers/body/cookies and see how a server response is structured.
Evaluate password structure using non-real examples and observe SHA-256 avalanche behavior safely in the browser.
Create allow/block rules and test simulated traffic to understand how defensive filtering decisions are made.
Switch between Student and Admin roles to understand authentication, authorization and server-side protection.
Play through prepared security events, triage alerts and investigate suspicious authentication and integrity activity.
Investigate a prepared incident and arrange detection, containment, eradication, recovery and lessons learned in order.
Stage 2 gives students interactive execution and realistic analysis while keeping network actions deterministic and contained. This is ideal for classroom understanding before moving to isolated VM/container targets.
