A Paper on Security in Cloud Computing

We would like to provide the benefits of cloud computing without any troubles to propel in the direction it is designed for. This is to be achieved by preventing the owner's data from all risks associated and providing a cloud model that is more secure and efficient. The proposed model shall overcome the security risks defined by the security functions over cloud computing, as follows in (Passent M. et al., 2015):

The economic case for cloud computing is compelling and at the same time there are striking challenges in its security. The concepts of cloud computing security issues are fundamentally new and intractable. What appears new is only relative to traditional computing that has been practiced since several years. Many such security problems have been giving attention since the time-sharing era. Cloud computing providers have and can build datacenters as large due to their expertise in organizing and provisioning computational resources at

The cloud computing has more security threats from the cyber hackers, to avoid the cyber-attacks on the cloud the organization must take concerning the cloud security problems like privacy, trust, authentication, data loss. Though the cloud anyone can access the computing technology and the storage of data from the network, as it used for the network cause

By introducing the intense programming which were extremely difficult to hack the servers move toward becoming more secure however it includes certain financial costs furthermore for the organizations which were eager to upgrade to such security components. Centralization is likewise one more factor that makes the cloud innovation the most secure one as it guarantees the simple control particularly to the customers of PaaS and IaaS models. Cloud security is centered around the single area on the primary server which is much better than the idea of individual organizations controlling the security of various servers at various areas. Through cloud security better treatment of the framework in a sheltered and secure way is accomplished. In organizations, if business is coordinated with the cloud administrations they may confront bring down dangers and enhance responsibility and kept up since the cloud specialist co-op is in charge of taking care of the whole thing. Therefore, the business require not to have money related incurrence and due to this reason it is important to pick the most committed organization to give the administrations, further developed safety efforts should have been actualized. The organizations in a need to guarantee development via completing the profound examination with respect to the

This section of paper includes why we need cloud computing as a security control tool against the cyber criminal activities and in how many ways it can be implemented. As we are living in a technical era, many aspects of our lives rely on the Internet and computers, including transportation, communications, government, medicine, finance and education. Consider how much of our personal information is stored either on our own computer or on someone else’s system.

In this fast-paced technology era, organizations are always looking for new innovative ways to increase productivity and efficiency. One emerging technology adopted by many organisations is cloud computing. Cloud computing is a model that uses internet and remote servers for maintaining data and applications (Association of Modern Technologies Professionals 2017). It replaces expensive infrastructure and need of maintenance. Cloud provides access to data anytime, anywhere over the internet. However, like any cyber technology cloud computing is vulnerable to various kinds of cyber-attacks (Amna Riaz 2017).

The objective of this research is introducing the Trusted Computing based security mechanism to the cloud.

Cloud computing has provide the software and services the demand of the client. It offer the client to connect to computer resources and access the resources with a previously unknown level of ease because of this new cloud become the new ground of development of a generation of delivering service and store the privacy and security may be include security concern among user of the cloud have become concern of cloud.

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

Cloud computing has numerous advantages to businesses today. It enables scalability of services that are delivered over the internet when needed. User data is stored in remote servers that the users do not operate. This brings unprecedented convenience. Although it brings so many advantages and efficiencies, cloud computing results to fears arising from loss of data control. This becomes a hindrance to the wide adoption of the emerging technology. As a way of solving these problems, techniques have been developed to ensure that data held in the remote servers is secure and that it cannot be used to achieve malicious activities targeted against the owner of the data.

ABSTRACT: Cloud computing is a method of providing a set of shared computing resources that includes applications, computing, storage, networking, development, and deployment platforms as well as business processes. In cloud computing, data while transferring as well as storage, and get data back when it is needed there is no assurance about the security of that data stored and also it is not changed by the cloud or TPA. Therefore Security and control over data remain to play a significant role in plans for cloud computing initiatives. Existing research work earlier grant data integrity to be verified,but still there are different drawbacks, firstly basic and mostly needed authorization/authentication process is not present in between Cloud Service provider and TPA. Techniques like authentication and encryption are important, our system can provides those things for security issues. Second: in recent research POR protocol in which the verifier stores only a single cryptographic key, POR can only capable of detection of file corruption or loss, and not prevention. Maintaining the storages can be a tough task and second it requires high resource costs for the implementation. This paper, Propose a formal analysis method called full

Cloud computing’s existing security model To obtain maximum security of cloud computing system, some tools and technologies are using. The cloud computing security can be provided as security services. Therefore, security issues for many of these system and technologies are applicable to cloud computing. The Secured Computing Platform The SCP handled by a combination of hardware and software: manufacture adds new hardware to support to trust computing functions and design special operating system that becomes mediator between hardware and application to support trusted computing. Construct trust cloud computing system using SCP With help of trusted computing, we can provide a way to establish secure environment in cloud. Cloud computing service has been integrated with web technology in that case we need to provide trusted computing system to secure data and application. Authentication cloud computing environment with LDAP In cloud computing, different users want to join cloud so they have to prove their identities before join cloud. When users have full information about them (identification) so it is easy to trace the users and that mechanism will implement for cloud and get the record of users and trace them. Person Based Access Control Model in cloud computing environment there are too many users in cloud computing system that wants to access the resources. To attain the objective of trusted computing, users has to come

Nowadays, cloud computing has penetrated into every corner of Internet industry with its low-cost computing resources, easy scaling architectures, and everywhere on-demand services. Security issues is the most important issue faced by people in the use of cloud computing data storage services [1].The advantage of cloud is cost savings. The prime disadvantage is security. The security risks associated with each cloud delivery model vary and are dependent on a wide range of issues counting the understanding of data quality’s, cloud architectures and safety measures organizes engaged in a exacting cloud atmosphere. With public audit capability, a trusted entity with expertise and capabilities data owners do not hold can be entrusted as an outside

Cloud computing security or, more simply, cloud security refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing. It is a sub-domain of computer security, network security, and, more broadly, information security [1]. With the extensive use of virtualization technologies combined with self-service potentialities cloud service providers are providing services to their customers through the Internet. In these service provider surroundingses, virtual machines from different multiple organizations have to be co-located on the same physical server in order to optimally maximize the effectiveness and efficiencies of virtualization. Cloud service

Cloud computing is a model for enabling convenient and on-demand network access to a shared pool of computing resources.One of the major characteristics of the cloud services is that users’ data are processed on unknown remote servers which are not under the control of service owner.Multiple users want to do business of their data or application using cloud , but their fears of losing control over their data or application become a barrier to the wide adoption of cloud computing services.Data owner must get confirmation that his/her data is safe on the cloud. To solve these problems, here proposes a highly decentralized framework to monitor the actual usage of the user’s data available on the cloud.The framework proposed in this work performs automated logging and distributed auditing of relevant access performed by other entity, occured at any point of time at any cloud provider . Software as a service model is considered in this work. The methodology includes an object centered approach that uses JAR programmable capabilities to create an object that contains service owner’s policies and data.When the data are accessed by any external entity, logging mechanism is automatically triggered at the moment itself.Automatic JAR checking is also done to verify the trustworthiness of the cloud server.Data encryption technique,policy checking and technique to
