Security Threats and Challenges in Cloud Computing

Cloud Computing has emerged as a new paradigm of computing that builds on the foundations of Distributed Computing, Grid Computing, and Virtualization. Cloud computing is Internet-accessible business model with flexible resource allocation on demand, and computing on a pay-per-use as utilities. Cloud computing has grown to provide a promising business concept for computing infrastructure, where concerns are beginning to grow about how safe an environment is. Security is one of the major issues in the cloud-computing environment. In this paper we investigate some prime security attacks and possible solutions for clouds: XML Signature Wrapping attacks, Browser Security, and Vendor Lock-in.
