Competitive Cybersecurity 101: Course Materials & Lecture Archive

"We are in the most dangerous period, the transition when attackers might gain a significant advantage as the technology ecosystem digests the impact of AI... Falling behind is not an option."
— Jim Zemlin, CEO of the Linux Foundation

The official open-source repository for Competitive Cybersecurity 101. This educational initiative is designed to equip students with the foundational skills, technical pipelines, and ethical frameworks required to compete in the National Cybersecurity Olympiad (NCO) and the International Cybersecurity Olympiad (ICO).

Originally developed for the Cybersecurity Club at DPS International School, Singapore, this curriculum is freely available to educators, students, and self-taught enthusiasts worldwide.

Ethical Framework & Disclaimer

Lecture 1B: Python Foundations for CTF Scripting

Date: July 24, 2026
Instructor: Kannan Murugapandian
Description: Python is the industry standard for cybersecurity automation. This session bridges fundamental programming concepts with their direct application in CTF challenges. Topics include Python data types, string manipulation, ASCII/Unicode translation, and the critical distinction between encoding (Hexadecimal, Base64) and encryption. The lecture culminates in practical control flow mechanics (loops and conditionals) required for automated data parsing and pattern recognition.
