Siebel Security Guide > About Security for Siebel Business Applications > Siebel Security Architecture > Controlling Access to DataAuthorization refers to the privileges or resources that a user is entitled to within Siebel Business Applications. Even among authenticated users, organizations generally want to restrict visibility to system data. Siebel Business Applications use two primary access-control mechanisms:
Access control provides Siebel customers with a unified method of administering access to many content items for many users. For more information, see Configuring Access Control. View-Level Access ControlOrganizations are generally arranged around functions, with employees being assigned one or more functions. View-level access control determines what parts of the Siebel Business Applications a user can access, based on the functions assigned to that user. In Siebel Business Applications, these functions are called responsibilities. Responsibilities define the collection of views to which a user has access. An employee assigned to one responsibility might not have access to parts of the Siebel Business Applications associated with another set of responsibilities. For example, typically a system administrator has the ability to view and manage user profiles, while other employees do not have this ability. Each user's primary responsibility also controls the user's default screen tab layout and tasks. Record-Level Access ControlRecord-level access control assigns permissions to individual data items within an application. This allows Siebel customers to authorize only those authenticated users who have to view particular data records to access that information. Siebel Business Applications use three types of record-level access: position, organization, and access group. When a particular position, organization, or access group is assigned to a data record, only employees within that position, organization, or access group can view that record.
