Abstract

There are a lot of security issues in cloud computing service environments such as virtualization,

distributed big data processing, serviceability, traffic-handling, application security, access control,

authentication, cryptography and etc. Especially, data access using various resources needs authentication

and access control model for integrated management and control in cloud computing environments.

Cloud computing service provides a differentiated service according to component of security

policy because a permitted limit of service provider and user are different. RBAC(Role-Based Access

Control) and C-RBAC(Context-Aware Role Based Access Control) do not suggest effective and

practical solution using dynamic access control method by manager and user. Therefore, new dynamic

access control model needs to make up for the weakness of existing problems according to

cloud computing characteristic. In this paper, we propose Onto-ACM(Ontology Based Access Control

Model) for dynamic access control. Onto-ACM is a semantic analysis model for permitted limit

of service provider and user. This proposed model is the intelligent context-aware access model for

applying the proactive security level of resources access using context information ontology modeling

and reasoning engine.

Keywords: access control model, cloud computing, ontology reasoning, semantic analysis model
