QoS of Security Threats and Solution in Cloud Computing Organization

Cloud computing was used to deliver a service through a network. Generally, it used for storing data and accessing services over through Internet. The cloud service models are Infrastructure as a service (IaaS), Platform as a service (PaaS), Software as a service (SaaS), Storage as a service, and Desktop as a service. Cloud basic characteristics are maintenance, performance, security and cost reduction. The most popular cloud service providers are AWS (Amazon Web Services) and IBM. Cloud deployment models are Private, Public, Hybrid and Community cloud. Cloud services major drawbacks are security. Since many cloud providers shares users data to third parties. This paper mainly focus on how to secure users data which are stored under cloud organization. Since, quality of the cloud service provider was standardized by security. Here, algorithm used RSA (Rivest-Shamir Adleman) algorithm. It was an public key encryption technology. By developing the strong login process by encrypting data and providing security alerts in case of emergency.
