Applying authentication and network security to in-cloud enterprise resource planning system

Abstract

The service-oriented hosts in enterprises like enterprise resources planning (ERP) system have always encountered the crucial problem of unexpected down-time or system failure that will cause data loss and system termination. Failover is a challenge issue that cannot be done successfully between physical hosts. Traditional information security using demilitarized zone approach costs a lot. Therefore, this paper introduces in-cloud enterprise resources planning (in-cloud ERP) deployed in the virtual machine cluster together with access control authentication and network security which can resolve the three problems mentioned above. Access control authentication and network security have been implemented in the cloud computing system to prevent the service-oriented hosts form external fraud, intrusion, or malicious attacks. As a result of the experiments the number of accessing in-cloud ERP is 5.2 times as many as in-house ERP. The total expenditure of in-cloud ERP has decreased significantly to 48.4 % the cost of in-house ERP. In terms of operational speed, the approach proposed in this paper outperforms two well-known benchmark ERP systems, in-house ECC 6.0 and in-cloud ByDesign.
