Cloud computing relies on a change in perspective with ramifications in computational issues. Ideal models moving to cloud computing are the fundamental mainstay of progress in traditional computational models for addressing problems concerning information security and protection. The various components concerned with security and protection types of problems are shown in Table 2.1 and discussed below.

Table 2.1: Shared responsibility model for security of cloud computing.

 User information restrained by third-party service: Currently, domination is surrendered to the third-party services; thus, extraordinary security and protection problems concern allied unapproved ingress, information ingress restraint, information debasement, upgrading non-static allotment methodologies, restraining sensitive data stream and so forth. As far as third-party service is concerned, customers store their precise information in the database and storage service provided by a third party. Thus, outsiders have the obligation to keep up the security and protection of the information, which is the reason why outsiders need to empower an inspecting service. As per information systems control and audit, IT reviewing could be characterized as a procedure of conglomerating and assessing confirmation to choose whether a computational information framework shields resources, maintains information trustworthiness and secures sensitive user information, accomplishes hierarchical goals adequately and expends physical and computational resources proficiently.

 Information is stored in different locations which are regulated by numerous associations: Cloud services are provided by various CSPs, which maintain hardware components, such as processors, memory and storage, in individualized parts. Therefore, the user information is stored in numerous locales which are controlled by a few associations. Thus, the purported “issue of numerous ways” could emerge based on the capacity of specialists and/or people to process and manage the administration by the accumulation, utilization, distribution and revealing of their personal information by others. Boundless universal information utilization, information sharing and pools of information storage among the associations would become an issue in the perplexing association of cloud services. It is very hard to verify who will assume the liability if anything undesirable happens to stored information. All the logging information must be checked and should keep information acquisition, information transmission or information change.

 Accountability: This is another part of protection and security. Sufficient data is needed with respect to how information is overseen by the CSPs so they can keep track of information acquisition, information transmission or information change. That is the reason why the representatives of associations authorize the standards and directions used to maintain bookkeeping records.
