Hello, I'm Kanchuka (or RicheByte online). I focus on cybersecurity and creative development because I'm genuinely curious about how digital systems work and how to make them secure.
My work involves studying network protocols, concentrating on writing secure code, and understanding both offensive and defensive security techniques. I believe it's important to create systems that are strong and safe, but also easy and intuitive to use.
Proficient in Python, JavaScript, Bash for automation, tool development, and web applications.
Network security, vulnerability assessment, penetration testing fundamentals, security audits, incident response concepts.
TCP/IP stack, routing, switching, firewall configuration, VPNs, network analysis tools (Wireshark).
Linux (Debian/Ubuntu, Kali), Windows Server/Desktop administration and hardening.
Developed a Python-based network scanner using Scapy library capable of various scan types (TCP SYN, UDP) with options for stealth techniques to minimize detection during assessments.
Tech: Python, Scapy, Argparse
A command-line tool written in Python for encrypting and decrypting files using AES-GCM, providing both confidentiality and integrity. Includes secure password handling via hashing.
Tech: Python, Cryptography library, hashlib
Designed a concept for a web dashboard using Flask/Django to aggregate results from various security scanning tools (e.g., Nmap, Nikto) providing a unified view of potential vulnerabilities.
Tech: Python (Flask/Django - Planning), HTML, CSS, JavaScript
Simulated cyber attacks to identify vulnerabilities in networks and web applications (Ethical hacking focus).
Reviewing configurations, policies, and infrastructure against security best practices to identify gaps.
Guidance on incorporating security principles (OWASP Top 10, secure coding) into the software development lifecycle.
