Introduction To ACL

In this tutorial I hope to display to you the value of Access Control Lists (ACL)! For those of you who don't know, access control lists are an easy and simple way to manage permissions and security in your applications. This is just one more step to MVC programming, and is a great help (Look for my tutorial on Class Diagrams). An ACL performs two basic operations: A) The handled, B) The Handler. The handled are referred to as Access Control Objects (ACO) and the handler is referred to as Access Request Objects (ARO). We refer to these as Objects due to the fact that you don't have to be a person to request any of the ACOs. So putting all of that knowledge together, ACL is what decides which ARO is granted access to each ACO.
