# Cybersecurity Portfolio This repository contains my hands-on cybersecurity learning, lab writeups, and Python-based networking/security tools built while exploring web security, Linux systems, packet analysis, and offensive security concepts. A large part of this repository comes from practical experimentation through: * Hack The Box * PortSwigger Web Security Academy * Hacker101 CTF * Linux lab environments * Packet analysis using Wireshark * Python networking projects # Areas Explored * Web Application Security * Cross-Site Scripting (XSS) * Access Control Vulnerabilities * Packet Analysis * Network Enumeration * Linux Privilege Escalation * Burp Suite Workflows * Wireshark Analysis * HTTP Request Manipulation * Python Security Tooling * Networking Fundamentals # Repository Structure writeups/ ├── hackthebox/ ├── portswigger/ └── hacker101/ tools/ ├── network-scanner/ ├── packet-analysis/ ├── mitm-lab/ ├── dns-security/ ├── network-identity/ └── payload-lab/ # Featured Writeups ## Hack The Box * Cap ## PortSwigger Labs * XSS Labs * Authentication Labs * Access Control Labs ## Hacker101 * Micro-CMS * Postbook * Petshop Pro # Tools This repository also contains small Python-based networking and security-related scripts created while learning about: * packet sniffing * ARP spoofing * DNS manipulation * MAC address configuration * network scanning * HTTP traffic interception These were developed strictly in controlled lab environments for educational purposes. # Current Focus Currently revisiting and rebuilding my cybersecurity foundations through: * practical labs * writeups * networking concepts * packet analysis * web security testing * Linux enumeration # Disclaimer All work in this repository was performed in legal and controlled environments for educational and defensive security learning purposes only.
