Explain the difference between authentication and authorization with a real-world example
Great question! Think of it like entering a building:

Authentication = showing your badge at the door (proving who you are)
Authorization = the floors your badge can access (what you're allowed to do)

In AWS terms: IAM login = authentication, IAM policies = authorization.
Now quiz me on IAM concepts from Chapter 5
