Master the Fundamentals of Networking & Infrastructure
TCP/IP, OSI model, firewalls, segmentation and perimeter defense architecture. The technical foundation for any cybersecurity career.
[ Presentation Video ]
The Problem
You freeze in cybersecurity interviews on networking questions — subnetting, TCP flags, TLS handshake. The technical foundation isn't solid.
Who It's For
IT students, help-desk staff and professionals moving into cybersecurity without solid networking fundamentals.
What You Take Away
By the end, you read Wireshark captures, design DMZ topologies and explain a packet's full path — solid base for Blue Team, Red Team or Cloud. — technical foundation that opens doors to SOC, Pentest, Cloud Sec or Network Engineer roles.
What You Will Master
OSI Model and TCP/IP
The 7 layers, encapsulation and fundamental network protocols.
Firewalls and Perimeter Defense
ACL rules, DMZ, reverse proxy and defense in depth.
Network Services
DNS, DHCP, HTTP/HTTPS, SMTP and where the risks lie in each service.
Monitoring and Troubleshooting
Wireshark, tcpdump and traffic analysis for problem diagnosis.
