Below is a list of commonly used terms for SAP Security.
Application Link Enabling (ALE)
Integration technology that integrates processes between external legacy systems as well as SAP systems. Data and messages are exchanged between this application systems in a controlled and consistent manner. This provides SAP customers with a distribution model that enables the programs to interconnect across various types of systems and platforms. There are three layers to the ALE: communication services, application serivces, and distribution services. The use of an intermediate document (iDoc), a container for the data, is commonly used to transmit data in between applications. An RFC (Remote Function Call) is performed on the communication layer, using an RFC destination specified in the model and a port definition.
Central User Administration (CUA)
The CUA allows for easier maintenance of users across multiple systems within a single system. A number of “child” systems/clients can be connected to the CUA; thus allowing the managing of all the users in the “child” systems through the CUA. Through transaction SCUM, you can set parameters that will set certain user administration activities be run specifically through the CUA or the “child” system. For example, user parameters can be maintained in the “child” system while role assignments be kept with the CUA.
This refers to any type of service, application, or information, that can be seen in a internet browser frame. iViews are shown in a container known as a tray, a type of functionality for using an iView. iViews are self-contained web documents that are provided through a URL (Uniform Resource Locator) managed by an SAP portal framework. An iView must always provide the user with added value.
