A Standardized Model for Role-Based Access Control
Abstract: Mechanisms
must be provided to protect resources from attackers when users call for
sharing access to resources in the computer network circumstance. Role-Based
Access Control (RBAC) formulates that access decisions are based on the roles
that individual users have as members of one system. However, the lack of
standards for RBAC has led to roles being implemented in different ways,
impeding the advance of RBAC technology. The NIST RBAC model seeks to solve
this problem by unifying ideas from prior RBAC models. It is organized into
four levels of increasing functional capabilities called flat RBAC,
hierarchical RBAC, constrained RBAC and symmetric RBAC. This presentation is to
focus on analysis of above core features to provide a clear outline of the
standardized RBAC model.
