What do I need Amazon GuardDuty for?

Amazon GuardDuty is like a security guard for your cloud data. Imagine you have a house (your cloud data) on the internet where you keep all your valuable stuff. GuardDuty is a service that watches over this house 24/7, looking for anyone trying to break in or do something suspicious. It uses smart technology to learn what normal activity looks like and can spot when something unusual happens. This way, it helps keep your data safe without you having to do much or install extra equipment.

Let's say you run a small online store where you keep customer information and sales data on AWS (Amazon Web Services). You want to make sure no one can steal this information. Here's how you can use GuardDuty to protect it:

It's useful for Activate GuardDuty, Automatic Monitoring, Getting Alerts, and Taking Action.

I drew a diagram to show how GuardDuty fits into your AWS environment:
