Cloud computing is an emerging and upcoming field of discussion and advancement in computer science. This is mainly due to its popularization in the world of computing which has happened due to its limitless applications like Gaming, education, health care, It enterprises, daily life and many more. Accessing confidential data from cloud is an issue of concern as many users at a time can have access to the same cloud. Moreover, some users accessing the cloud information can be malicious and can destroy the data stored in the clouds which makes cloud computing suspicious and less reliable to use. Users may think that it’s more secure to save your data on the personal machine rather than accessing through a common cloud which is accessible to all. Keeping in mind these cons a concern is raised about the security issues in cloud communication. The two ways of accessing data from clouds are intra-cloud i.e. accessing data within the cloud and inter-cloud communication i.e. accessing data from different clouds to fulfill user requirements. Although the intra-cloud communication is secured from outside threats, there are still prevailing security risks due to the transferred data between two services could potentially be ‘visible’ to the cloud provider. It is possible for a malicious neighbors for instance within the same physical machine or LAN to sniff the transferred data. However, inter-cloud communication raises an even higher security risk than that in intra-Cloud communications because the transferred business data goes through multiple cloud infrastructures and the entrusted public Internet. Considering the above points a review paper on various security issues in inter-cloud communication is written in which various reasons of security threats posed to inter-cloud communication are discussed with their potential solutions.
