The jFramework Role Base Access Control is the all-in-one solution for access control and authorization in jFramework. It supports a wide range of features and is based on the level 2 NIST role based access control standard, the Hierarchical RBAC with a few add-ons to that.

Overview

Role-based access control has quite widely become the access control subsystem architecture used in many major and minor software. To unify the implementations, NIST has published a standard, consisting of four different levels:

• Flat RBAC
• Hierarchical RBAC (inheritance for roles)
• Constraint RBAC
• Symmetric RBAC
