A complete technical documentation of my Cyber Security learning journey.
This repository includes structured notes, commands, walkthroughs, and explanations for every module and room in the TryHackMe Cyber Security 101 Path.
The Cyber Security 101 pathway by TryHackMe is a beginner-friendly track introducing core concepts in networking, cryptography, MS Windows, Linux basics, operating systems, offensive and defensive security, and career fundamentals.
This repository serves as a technical study notebook, containing:
- 14 Modules
- 56+ Hands-on Labs
- Commands, tools, methodologies
- Room-by-room documentation
- Structured explanations and cheat sheets
Mindset and deeper thought-process content will be published separately on Medium and LinkedIn.
This path builds foundational knowledge in:
- Computer Networking & Cryptography
- Linux & Windows Fundamentals
- Active Directory Basics
- Command Line (Linux Shell, CMD, PowerShell)
- Networking Tools: Wireshark, tcpdump, Nmap
- Offensive Security & Exploitation
- Web Application Security
- Defensive Security & SOC Concepts
- Security Solutions (SIEM, IDS, Firewall)
- Malware Analysis Tooling (CyberChef, CAPA, REMnux, FlareVM)
- Cybersecurity Career Guidance
- OWASP Top 10 (2025)
