A model for checking consistency in access control policies for network management
Abstract
This paper addresses the consistency of initially heterogeneous access control policies in the network management area. It addresses the well-know network management frameworks like SNMP (v3), CLI, Netconf and the lesser known TR-069 proposed in the framework of ADSL operators. For each of these, a formal definition of the access control model is proposed as well as the conversion towards a unified Role-Based Access Control model. Next, we show how to compare roles and permissions between the generated access control policies and to answer to questions like: which policy is more permissive, what are the common privileges between a set of roles ?
