Security Issues in Cloud Computing: A survey

Abstract

Cloud computing is attracting great attention nowadays. The elastic nature of cloud makes it suitable for almost any type of organization. The major challenge faced by cloud users and providers are security concerns towards cloud services. These security issues acts as a barrier in the growth of cloud computing. The trust between provider and users is the most important factor to be considered for a cloud service and application. The notion of trust among the various cloud users is also essential to promote the reputation of various cloud providers and their offered services.Here we present an analysis of security issues in a cloud environment. Solution exists to a certain extent for various issues. There are trust based solutions available to provide security in various collaborative environments. Analysis of these solutions can be used to think about a trust based solution in a cloud computing environment.

User Behavior Trust Modeling in Cloud Security

“…The cloud's resources are located at an off-site location, making this model's deployment less secure and riskier than others because malicious activities can occur with the service delivery models. In this case, customer-to-provider servicelevel agreements (SLAs) must be well detailed and analyzed [17,18].…”

“…Due to specified internal exposure, private-cloud usage can be much more secure than a public cloud. Only the organization and designated stakeholders can access a private cloud [17,18].…”

“…A hybrid cloud is traditionally considered a mix of private and public clouds, bringing together the advantages of each type and overcoming their barriers. This model is managed by both the organization and a third-party entity and is located both on-and off-site [17,18].…”

Multi-Level Data Integrity Service

“…Service Availability: Administration of computing assets by a single company infers the threat of a single point of failure. This issue is solved by storing the data on multiple clouds [10]. Whereby no single entire copy of the data resides in one position and only a subset of providers requires being obtainable in order to recreate the data.…”

Efficient Data Possession Auditing for Real-World Cloud Storage Environments

“…Despite its benefits and popularity, this new data hosting paradigm introduces additional security challenges [16]. Users are frequently concerned that their outsourced data may become damaged or lost for various reasons; they may also be concerned that SSPs might attempt to conceal data loss incidents caused by administrative errors in order to preserve their reputations, or discard data that are rarely accessed.…”
