Abstract
This paper discusses cloud ERP security challenges and their existing solutions. Initially, a set of definitions associated with ERP systems, cloud computing, and multi-tenancy, along with their respective challenges and issues regarding security and privacy, are provided. Next, a set of security challenges is listed, discussed, and mapped to the existing solutions to solve these problems. This thesis aims to build an effective approach to the cloud ERP security management model in terms of data storage, data virtualization, data isolation, and access security in cloud ERP. The following proposed techniques are used to improve the security for multi-tenant SaaS: database virtualization, implementation of data encryption and search functionality on databases and developed systems, distribution of data between tenant and ERP providers, secure application deployment in multi-tenant environments, implementation of the authentication and developed systems together as a two-factor authentication, and improved user access control for multi-tenant ERP clouds.
Highlights
This section focuses on the main purpose of securing cloud enterprise resource planning (ERP) systems, a new proposed model to secure the cloud ENTERPRISE RESOURCE PLANNING (ERP) environment
The primary focus is on the services provided by software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS) to discuss the main problems and issues associated with the security and privacy thereof
Cloud-based ERP is a development of integrated business suites supporting ERP, CRM, and ECommerce capabilities where application modules can be accessed using the software as a service (SaaS) delivery model, and where application users have flexibility to configure and subscribe to a set of application modules based on an architecture called multi-tenancy [12][25]
Summary
This section focuses on the main purpose of securing cloud enterprise resource planning (ERP) systems, a new proposed model to secure the cloud ERP environment. We aim to investigate and discuss the potential security issues and challenges arising from cloud ERP and list some existing solutions. The research methodology is based on a literature review of cloud ERP systems to define the security challenges and issues arising from the cloud ERP from the perspective of both the user and service provider. We use the best ideas and suggestions collected in the literature review to propose a model to improve the security and privacy in the cloud ERP.
