Integrated Access Control Management

. In this paper, we discuss access control for objects distributed over heterogeneous network management systems. In particular, we compare the access control mechanisms of SNMP version 2 against those proposed for CMIP. We employ the Typed Access Matrix model as a framework to study the two approaches in detail. Apart from the differences due to their management model, both schemes use an identitybased ACL scheme on object groups defined as collections of subtrees. We present an access control scheme integrating both systems.
