Hands-on Network Security Basics
This course is essential training for someone who wants to learn network security.
Everything in this course is based on real-world questions that I collected /arranged for days one, two, or three of network security training. So even if you think this course is too easy, you can still use this as training material for your team.
Also, I put priority on dealing with time-tested attack vectors that constantly revive. Threats would not suddenly come alive. Instead, most of them were remodeled and disguised as new.

ARP traffic investigation
+ Datalink layer
Routing/ packet filtering challenge
+Network layer
HTTPS decryption/ interception
+ Trans-App layer
Web Application Firewall
+ Wrap up practice
VPN fundamentals (ssh tunneling/split-tunneling)
+ Trans-App layer
Logs and security device config files analysis
+ Python ttp and Jinja2 : convert semi-structured data to 2 dimensional dataset
[how I made this course:]
collected half-answered or unanswered network security-related questions from famous tech QA sites, security vendors' community sites and Github issues.
picked easy to intermediate ones
made complete answers to them (really time-consuming!)
arranged QAs so we can replicate the issues individually (insanely time-consuming!)
intended audience :
Software developers who usually don't handle NW security problems
Customer Success engineers who want to analyze NW security problems quickly in an isolated environment
NW engineers who are having a hard time understanding weird NGFW UTM /Sandbox alerts
what we're going to do:
Generate malicious traffic using popular tools and feed that traffic to pcap analysis tools to see how they analyze the traffic.
Play with Brim ( pcap analysis tool powered by Zeek and Suricata with SEIM-like searching interface).
learn practical network layering for troubleshooting
code Python scapy to analyze layer two attack
solve real-world routing/filtering issues in Docker environment
analyze typical covert tunneling methodologies
