Leveling up from Class 10 ICSE to Polytechnic! Here is why I think even beginners need to look at code through a security lens. 👁️💻

Hey everyone! 👋

I’m Ch Hima Kartikeya Naidu. I just finished my Class 10 from an ICSE school, and I’m about to start my diploma journey. My ultimate dream is to build a career in Cyber Security, but on the side, I’m also a small-scale game developer who loves using storytelling and creativity to craft engaging narratives and virtual worlds.

Since I'm just entering polytechnic, my programming peak right now is mastering loops Python and C. I aced basic Java in my academics. While learning how loops repeat actions to make games work, I started wondering: How do these same basic programming concepts connect to cyber security?

Here is how I’m looking at security as a beginner dev:

1. When Loops Turn Into Security Flaws (Infinite Loops)

In my classes, I learned how to use loops to repeat code until a condition is met. But what happens if a programmer makes a mistake and the loop never stops? It creates an infinite loop that freezes the software. In the security world, if an attacker finds a way to trigger an infinite loop on a server, they can crash the whole system. This is a basic form of a Denial of Service (DoS) vulnerability.

My Lesson: Writing secure code starts with making sure your loops always have a foolproof exit strategy.

1. Game Exploits vs. Real-World Hacking

As a small-scale game dev, I know that if you don't secure your variables, players can use memory-editing tools to change their in-game currency or health from 10 to 9999. In the cyber security world, this is very similar to a "Buffer Overflow" or memory tampering, where an attacker alters data in a computer's memory to make it do things it shouldn't.

My Lesson: Whether it's a video game or a secure database, you can never trust what's happening on the client's side without validation.

1. C Language and Memory Safety

Learning C has been eye-opening because it forces you to manage memory yourself. A lot of famous cyberattacks happen because of vulnerabilities in C-based software where memory isn't handled safely.

My Lesson: Learning loops and memory management in C right now isn't just academic—it's actually the first step to understanding how system-level exploits work.

💡 Final Thoughts:

I might only know the basics right now, but I'm realizing that you don't need to be a master hacker to start thinking about security. It starts with the very first loops and variables we learn in school. I can't wait to level up both my security knowledge and my game dev skills during my diploma!
