Single Access Point

Classification Key : Perimeter Security, Information Disclosure


A security model is difficult to validate when there are multiple ways for entering the application. How can we secure a system from outside intrusion?


Set up only one way to get into the system and if necessary, create a mechanism to decide which sub-application to launch. Typically most applications use a log in screen to accomplish the single access point.

Known Uses

Login window in Windows, Unix, MacOS.
