Cyber Security Fundamentals
Learn how systems are attacked and defended: networking, core security concepts, web vulnerabilities, crypto basics, and hands-on labs. Best after Linux and networking basics.
Networking & OS foundations
Solidify TCP/IP, DNS, and operating-system basics — attacks make no sense without them.
Security core concepts
CIA triad, threat modeling, authentication vs authorization, and common attack classes.
Web application security
Find and fix the OWASP Top 10: injection, XSS, broken auth, and friends.
Cryptography basics
Hashing, symmetric and public-key crypto, TLS — and the classic ways they break.
Hands-on labs & CTFs
Practice offensive fundamentals legally on purpose-built platforms.
Defense & operations
Think blue team: detection, logging, and mapping adversary behavior with ATT&CK.
