This comprehensive learning path bridges the gap between foundational networking and enterprise infrastructure security. You will learn to administer, configure, and secure the core services that keep organizations running, while understanding exactly how attackers abuse them. Topics include DNS architecture and enumeration, DHCP rogue server mitigation, SMB/NFS file sharing pitfalls, web server hardening, email anti-spoofing (SPF/DKIM/DMARC), Active Directory core services, and NTP log synchronization. The path culminates in a capstone lab where you will audit and harden a multi-service enterprise network. Essential for aspiring network administrators, blue team defenders, and red team operators.
