Providing Security and Privacy in Cloud Computing Using Distributed Firewall and VPN

Dr. Chinthagunta Mukundha, Dr. I. Surya Prabha

Abstract: Cloud Computing is a flexible, cost-effective, and proven delivery platform for providing business or consumer IT services over the Internet. The main interest is to investigate the impact of using Virtual Private Network VPN together with firewall on cloud computing performance. Therefore, computer modeling and simulation of cloud computing with OPNET modular simulator has been conducted for the cases of cloud computing with and without VPN and firewall. However, cloud Computing presents an added level of risk because essential services are often outsourced to a third party, which makes it harder to maintain data security and privacy, support data and service availability, and demonstrate compliance. Cloud Computing leverages many technologies it also inherits their security issues cloud involves defined interaction with SLA based policies for the resource and service usages. If someone violates these rules the protection level of system gets compromised. Traditional security of the system is handled by the firewall. They are made for a static and fixed environment having limited policies and interactions. But in cloud environments the scenarios are changed totally and hence the behavior of firewall might also get adaptive as per the need of cloud computing.
