An intrusion-prevention system is like a superhero, but for your computer network. Just like how Batman keeps the bad guys out of Gotham, an intrusion-prevention system keeps the bad guys out of your computer network.
Think of your computer network like a castle with a big wall around it. The wall makes it hard for bad guys to get in, but sometimes they manage to sneak in. That's where the intrusion-prevention system comes in. It's like a bunch of guards who are always on the lookout for bad guys trying to get in.
The guards have special powers that let them detect when someone is trying to sneak in. They can tell if the person is not supposed to be there, and they can stop them from getting in. They can even tell if someone is trying to sneak in while pretending to be someone else, like a secret spy!
The important thing to remember is that an intrusion-prevention system is always on guard, looking out for bad guys and making sure your computer network stays safe. So just like how Batman keeps Gotham safe, your intrusion-prevention system keeps your computer network safe.
