Okay kiddo, so you know how computers work, right? Well, there's something called Linux which is like the computer's brain. And sometimes, bad people can hack into Linux and make it do things it's not supposed to.
That's where wifatch comes in. It's like a superhero that helps protect Linux from bad guys.
Wifatch is actually a program that runs on Linux and looks for any suspicious activity. If it finds something fishy, it tries to stop it and even lets the computer's owner know what's going on.
It's kind of like having a guard dog for your computer. Wifatch is always watching and making sure everything is safe and secure. So you can sleep well at night knowing that you have a superhero watching over your computer.
