| /** |
| * Implementation class that performs runtime access control operations on data objects of type Fortress entities |
| * This class performs runtime access control operations on objects that are provisioned RBAC entities |
| * that reside in LDAP directory. These APIs map directly to similar named APIs specified by ANSI and NIST |
| * RBAC system functions. |
| * Many of the java doc function descriptions found below were taken directly from ANSI INCITS 359-2004. |
| * The RBAC Functional specification describes administrative operations for the creation |
| * and maintenance of RBAC element sets and relations; administrative review functions for |
| * performing administrative queries; and system functions for creating and managing |
| * RBAC attributes on user sessions and making access control decisions. |
| * <hr> |
| * <h3></h3> |
| * <h4>RBAC0 - Core</h4> |
| * Many-to-many relationship between Users, Roles and Permissions. Selective role activation into sessions. API to add, |
| * update, delete identity data and perform identity and access control decisions during runtime operations. |
| * <p> |
| * <img src="../doc-files/RbacCore.png" alt=""> |
| * <hr> |
| * <h4>RBAC1 - General Hierarchical Roles</h4> |
| * Simplifies role engineering tasks using inheritance of one or more parent roles. |
| * <p> |
| * <img src="../doc-files/RbacHier.png" alt=""> |
| * <hr> |
| * <h4>RBAC2 - Static Separation of Duty (SSD) Relations</h4> |
| * Enforce mutual membership exclusions across role assignments. Facilitate dual control policies by restricting which |
| * roles may be assigned to users in combination. SSD provide added granularity for authorization limits which help |
| * enterprises meet strict compliance regulations. |
| * <p> |
| * <img src="../doc-files/RbacSSD.png" alt=""> |
| * <hr> |
| * <h4>RBAC3 - Dynamic Separation of Duty (DSD) Relations</h4> |
| * Control allowed role combinations to be activated within an RBAC session. DSD policies fine tune role policies that |
| * facilitate authorization dual control and two man policy restrictions during runtime security checks. |
| * <p> |
