Abstract&Cloud computing is one of recent technologies paradigm that attracted many computer users. Among these are big, small enterprises and individual users. Cloud computing brought a lot of advantages where users can access computer services through internet. With cloud computing, there is no need of physical components as hardware that will support the company’s computer system. Therefore, Cloud computing enables a set of entrepreneurs to start their business with zero investment on IT infrastructure. Data are stored and accessed in a remote server over internet. However, along with the good benefits of cloud computing has to offer, there are some security concerns which make users anxious about the safety, reliability and efficiency of migrating to cloud computing. So, before implementing cloud computing, organizations need to be aware of some security metrics. We will discuss about security concerns and analyze its level based on some of the proposed solutions. Keywords Cloud computing · Security level · Security metrics · Security issues

An Overview on Cloud Computing
Cloud computing is a method of providing a set of shared computing resources that includes applications, computing, storage, networking, development, and deployment platforms as well as business process[1]. Based on cloud computing taxonomy defined by the national Institute of Standards and Technology (NIST), there are three service models [2] in cloud computing which are: Software as a Service (SaaS): most known and first service, it is a major service given as a part of cloud computing. In this case, the application itself is provided by the service provider, typically via Web browser. E. Niyonsaba() · J.

Platform as a Service (PaaS): Providers deliver middleware (databases, messaging engines and so on) and solution stacks for application build, development and deploy. Infrastructure as a service (IaaS): it is the delivery of computing infrastructure as a service. Provider offers capacity for rent basically hosted data center and servers. In Cloud Computing, the management of the technology and services has moved from user to the service provider’s end. The cloud computing provides virtualized resources to the customers using various technologies, for example, Web services, virtualization, and multi-tenancy. The cloud services are delivered to the customer through the Internet. The Web applications are used to access and manage cloud resources that makes Web applications an important component of the cloud computing. The customers’ processes are executed in virtualized environment that in turn utilize the physical resources. Multiple vir
