A Survey on Threat Management in Cloud Infrastructure

The computational world is becoming very large and complex. Cloud Computing has emerged as a popular computing model to support processing large volumetric data using clusters of commodity computers. With the fast development of computing and communication technique, a high-quality of information area unit generated. Over the last years, cloud computing satisfies the applying necessities and grows terribly quickly. Basically, it takes the information process as a service, like storage, computing, information security, etc. However, along with desirable benefits come risks and security concerns that must be considered and addressed correctly. The investigation of potentials for secret communication in cloud environments and its possible application scenarios are needed. Security consciousness and concerns arise as soon as one begins to run applications beyond the designated firewall and move closer towards the public domain. Thereby, the current approaches of different kinds of secret communication including covert channels, side channels and obfuscation techniques have to be reviewed. This paper highlights and categorizes many of security issues introduced by the "cloud"; surveys the risks, threats and vulnerabilities, and makes the necessary recommendations that can help promote the benefits and mitigate the risks associated with Cloud Computing.
