Cloud Computing : Provide privacy and Security in Database - as - a - Service

Cloud computing Environment provides the platform to share computing resources and provide different services like SaaS, PaaS and IaaS that will used by organization as private, public or Hybrid. Cloud computing basically known as Everythingas-a-service .Since cloud computing is used shared distributed resources over the world wide network (e.g., internet) in the open environment, thus it will create various security issues in cloud environment and their application. On our personal computer we have full control on data and processes but in cloud environment we used data and application services which are provided by some of other Cloud Service Providers (CSP) (e.g., AWS, Google docs, Go Grid etc.).We overcome these issues of security and privacy by using Radius server which is known as AAA server (Authentication, Authorization and Accounting). Using this we will secure our CSP main server that further link with Data Center which store database of various cloud users. We use client password to encrypt and decrypt their data when they access or store data in Cloud Data Center (CDC).
