A Study on Security Issues in Cloud

AbstractCloud based E-Learning is the method to reduce cost and complexity of data accessing, which are controlled by thirdparty services. Traditional E-Learning methods are incorporated with cloud computing technology to provide massiveadvantages to the academic users but it compromises in security aspects. Proposed methodology ensures data availability and provides solution to protect indispensable data from the attackers. This study identifies different security issues incloud service delivery model with an aim to suggest a solution in the form of security measures related to the cloud based e-learning. Different types of attacks in service delivery models of e-learning proposed by different researchers are dis-cussed. Threats, security requirements, and challenges involved are also taken into consideration. This study of e-Learningmodels advocates users to access their data in the cloud through a secured layer using the internet
