Cloud computing security: attacks, threats, risk and solutions

Cloud computing started a new promising era in the field of IT and provided a new direction for the efficient use of resources, within the least amount. It becomes a centre of attraction for many organisations, as it allows the users to store data and use the resources dynamically, according to their requirements, from any remote location. But, the biggest challenge is to prevent data from malicious attack. Security and privacy are thus, gaining important consideration. Many researchers addressed various security requirements such as confidentiality, integrity, authenticity etc. in their work, but it is difficult to understand that which security requirements are still lacking behind to investigate. In this paper, we discuss the various possible attacks, threats, risks and security concerns with the possible countermeasures that need to be understood related to the cloud. The current research also investigates that how different cloud frameworks are affected by which network attacks.
