Today cloud is the most attractive place for the researchers. Everyone is trying hard to make cloud as secure service so as to confirm to CIA triad. Among various issues the security issue is of the huge importance. This study focuses on the security aspects of cloud computing so the vendors of cloud can provide security guaranteed storage service. The study focuses on availability, confidentiality and authentication procedures. Availability factor is most frequently targeted in clouds. Cloud is vulnerable to DDoS attack, hence the availability of the services are reduced. This study stresses upon the encryption and managing encryption keys by using any famous algorithm or by designing an improved one. Managing cloud data is one of the major challenges in cloud. Most of the Organizations consider security as their primary need for any web service. All sensitive information must be properly located in cloud environment.
