Cloud computing presents many unique security issues and challenges. In the cloud, data is stored with a third-party provider and accessed over the internet. This means visibility and control over that data is limited. It also raises the question of how it can be properly secured. It is imperative everyone understands their respective role and the security issues inherent in cloud computing.
Cloud service providers treat cloud security issues and risks as a shared responsibility. In this model, the cloud service provider covers security of the cloud itself, and the customer covers security of what they put in it. In every cloud service—from software-as-a-service (SaaS) like Microsoft Office 365 to infrastructure-as-a-service (IaaS) like Amazon Web Services (AWS)—the cloud computing customer is always responsible for protecting their data from security threats and controlling access to it.
Most cloud computing security risks are related to cloud data security. Whether a lack of visibility to data, inability to control data, or theft of data in the cloud, most issues come back to the data customers put in the cloud. Read below for an analysis of the top cloud security issues in SaaS, IaaS, and private cloud, placed in order by how often they are experienced by enterprise organizations around the world.
