Cyber Flow Explorer
GIF-clear Network view (laptop ↔ server, glowing packets), plus Sequence, Packet, and Code. Original CYNARKS curriculum — teaching simulations, not live capture.
Network Fundamentals (01–06)
Visual Learning Batch B1 — TCP, DNS, HTTP, TLS, ARP, routing/switching.
TCP 3-Way Handshake
See SYN → SYN-ACK → ACK open a reliable lab session.
3 steps · GIF network view
DNS Resolution
Browser → Resolver → Root → TLD → Auth → IP (lab zone).
5 steps · GIF network view
HTTPS / TLS Handshake
ClientHello → cert → keys → encrypted HTTP.
4 steps · GIF network view
HTTP Request & Response
See GET/headers go to the app and a 200 HTML response return.
3 steps · GIF network view
ARP Resolution
Host A broadcasts Who-has IP? — only the owner replies with MAC; others ignore.
4 steps · GIF network view
Network Routing & Switching
Internet → router → firewall → switches → hosts — path and trust zones.
3 steps · GIF network view
Catalog (web · infra · attack · SOC)
Full 24-scenario plan in Visual Learning; remaining engines ship in B2–B5.
TCP Connection Teardown
See the four-step close — each direction shuts down with FIN + ACK.

CDN, WAF & Reverse Proxy
User → CDN → WAF → App → DB; blocked SQLi stays at the edge.
5 steps · GIF network view
SQL Injection – Attack vs Defense
Unsafe string SQL vs parameterized defense on a mock DB.
3 steps · GIF network view
Authentication & Authorization
Login → session/JWT → role check → allow or deny.
4 steps · GIF network view
ARP Spoofing / MITM
Legit ARP vs spoofed mapping and why detection matters.
4 steps · GIF network view
Cloud IAM
User → role → policy → resource allow/deny evaluation.
3 steps · GIF network view
SOC Investigation
Logs → SIEM correlation → alert → analyst response.
4 steps · GIF network view
XSS Attack
Stored/reflected script execution vs encoding/CSP defense.
3 steps · GIF network view
API Security
Gateway → token validate → authz → rate limit.
4 steps · GIF network view
Malware Analysis
Safe sandbox timeline: delivery → exec → C2 → detect.
