Authentication and authorization are two distinct but interconnected processes in Active Directory.
Authentication: Who are you?
Authentication verifies the identity of a user or device trying to access a resource. It's like showing your ID at a bar to prove you're old enough to drink.
- Example: When you log in to your computer, Active Directory checks your username and password against its database. If they match, you're authenticated.
Authorization: What are you allowed to do?
Authorization determines what permissions a user or device has after they've been authenticated. It's like being given a menu at the bar, showing what drinks you're allowed to order.
- Example: Once you're logged in, Active Directory checks your user account's permissions to see if you have access to specific files, folders, or applications.
In summary:
- Authentication: Verifies your identity.
- Authorization: Determines your access rights.
Both processes work together to ensure secure access to resources in a network.
