What is hacking?
Hacking is like picking a lock in the digital world it’s all about finding a way into systems or networks. It’s done by super-smart people who know how to twist code and sneak past security. Some do it to test safety, while others aim to steal or cause trouble.
Think of hacking as a game of brains and tricks, played on computers instead of a board. It can be legal, like when experts help fix weak spots, or illegal when secrets get snatched. In 2025, hacking is everywhere, shaping how we protect our online lives.
What is Ethical Hacking?
Ethical hacking is like being a superhero of the internet using hacking skills to keep things safe. These hackers, called “white hats,” break into systems with permission to find weak spots before the bad guys do. It’s all about protecting companies, banks, and even you from cyber attacks.
Imagine a friendly spy testing a castle’s defenses to make it stronger that’s ethical hacking! In 2025, it’s a big deal because cyber threats are growing fast. Ethical hackers are the good guys who fight crime with keyboards instead of capes.
