Cloud Computing Security Challenges
User Authentication

Data resting in the cloud needs to be accessible only by those authorized to do so, making it critical to both restrict and monitor who will be accessing the company's data through the cloud. In order to ensure the integrity of user authentication, companies need to be able to view data access logs and audit trails to verify that only authorized users are accessing the data. These access logs and audit trails additionally need to be secured and maintained for as long as the company needs or legal purposes require. As with all cloud computing security challenges, it's the responsibility of the customer to ensure that the cloud provider has taken all necessary security measures to protect the customer's data and the access to that data.
