Security Concerns and Countermeasures in Cloud Computing Paradigm

Since the inception in 2006, cloud computing has been a hot researching area of computer network technology. Some giant companies are offering the cloud services now. Migrating data to the cloud remains a tempting trend from a financial perspective but there are several other aspects that must be taken into account before it is decided to do so. One of the most important aspects is security. Cloud computing security refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing. This work will enable researchers and security professionals to know about users and vendors concerns and identifies relevant countermeasures to strengthen security and privacy in the Cloud environment.
