Security Issues in Cloud Computing

Cloud computing is an emerging computing paradigm that offers the concept of time shared remote services with attractive technological and financial advantages. The infrastructure uses new technology and services which have not been fully evaluated with respect to security. A few of the concerns include data security, expectations, trust, regulations and performance issues. Cloud computing environments are multi-domain in which each domain can use different security, privacy and trust requirements and potentially employ various mechanisms, interfaces and semantics. The domain may represent individually enabled services or other infrastructural or application components. Service Oriented Architecture facilitates such multi domain formation through service composition and orchestration. As the shape of the cloud computing is emerging and rapidly developing conceptually and in reality, the issues such as contractual, service quality, interoperability, security and privacy issues pose serious challenges. In this paper an attempt is made to identify the challenges and suggest technological solutions to mitigate these challenges and facilitate ubiquitous adoption of this technology.
