Workshop Summary

In this workshop, we’ll cover the following areas to help you understand and effectively participate in CTF events.

What, Why, and How of CTF

We will cover what CTFs are and their importance in cybersecurity, especially for practicing real-world skills in a controlled environment.

We’ll also explore the different formats CTFs can take:

  • Jeopardy, Attack and Defense, King of the Hill, Story/Scenario-driven.
Types of Challenges

Next, we’ll discuss the various categories of challenges you’ll encounter:

  • Web, Binary Exploitation, Reverse Engineering, Forensics, Cryptography, Miscellaneous, Programming, OSINT, and Trivia.
Skills, Tools, and Techniques

This section will cover essential skills and why they matter:

  • Technical Skills and Tools: We’ll discuss the important technical skills that can help you perform well in CTF. And we'll.

  • Non-Technical Skills: These are just as important as technical skills. We’ll discuss why critical thinking, problem-solving, and creativity are essential, as they help you approach and solve challenges effectively. CTFs often require innovative approaches, and these skills will set you apart.
