A STUDY on SECURITY ISSUES in SaaS CLOUD COMPUTING

Cloud Computing is an Internet-based delivery of computing services, which include shared resources, software and data storage that are provided to the computing devices on demand. Cloud computing is very popular in distributed computing as well as used in our everyday. Cloud Services are provided on a leased basis and are mainly delivered by a third-party source which owns cloud infrastructure. Software as a Service (SaaS) is a software licensed delivery model that provides software through cloud. Saas has a feature of multi tenancy that virtually provides all the services at individual basis but physically all users can make use of the service at same time. In Recent Years, Saas has an increasing number of countries attention that promote SaaS Market. Even though SaaS provides attractive features, the Security Challenges are the main factor that makes SaaS in a critical situation. The Major Security Issues faced by SaaS include Data Confidentiality, Availability, Data Breaches, etc. In this paper we attempt to describe about SaaS Cloud Computing and Its Security Challenges.
