Security Issues and Challenges in Cloud Computing

IJCSMC, 2022

In today’s era almost all the organizations are preferring to use cloud as their primary storage. Once the organization uploads its data to cloud, then the organization has no control over it. Then comes the security challenges in handling data to cloud service providers. While selecting a Cloud Service Provider we need to be aware about that service provider before giving our data because as from now you will not have all the control. This paper gives a better understanding on the concept of cloud computing and the risks that came up after outsourcing data handling tasks. Section 1 is Introduction, Section 2 discusses on various Service Models in Cloud Computing, Section 3 contains Cloud Deployment Models, Section 4 focuses on Security Issues and Challenges in Cloud Computing.

Cloud computing is a new computing paradigm in the field of it that provides hosted services to a large number of user on demand basis over the internet. They are internet based network that has large numbers of servers. It allows to use the services only when you want and pay only for the amount what you have used. Since cloud computing share distributed resources over an open environment, so security becomes a major concern here. To improve the work performance different services are distributed on different servers but the security and safety aspects are remaining insufficient. Security is the one of major issues that hampers the growth of cloud. So, in this paper we first try to give an idea about cloud computing and then concentrate on the major security aspects of cloud computing paradigm.

Cloud computing is commonly used to represent any work done on a computer, mobile or any device, where the data and possibly the application being used do not reside on the device but rather on an unspecified device elsewhere on the Internet. The basic premise of cloud computing is that consumers (individuals, industry, government, academia and so on) pay for IT services from cloud service providers (CSP). Services offered in cloud computing are generally based on three standard models (Infrastructure-as s service, Platform-as a service, and Software as a Service) defined by the National Institute of Standards and Technology (NIST). The reason for cloud existence is to resolve managing problems being faced for data that were excessively stored, either mandatory capacity was limited due to the infrastructure of the business, or large capacity that led to a wasted capital. Apart from those major factors such as the initial capital, capitals and the service-fix cost, the sophisticated effort for the patching, the managing and the upgrading of the internal infrastructure is a huge obstacle for firm‘s development and mobility. For many firms where client and cultural competency have not got the strength to manage large data center environments and infrastructure, it would be wise to upload their files or data backups to another machine via internet, in order to concentrate more on the organizations primary objectives.

With the advancement of information technology, there is a need to perform computing tasks everywhere and anytime. There is also a need for people to be able to do their heavy computing work without expensive hardware and software through services. Cloud computing has been the latest technological answer to these needs. Cloud computing means providing processing services such as server, storage space, data center, network, software, data analysis and artificial intelligence on the Internet platform, which in order to increase the speed of innovation. Flexible access to resources and scalable economic benefits are used. Cloud computing is a new model for delivering information and services using existing technologies that use the Internet platform as a connection between the user and the server. One of the important issues is the focus of security challenges on new technologies. Cloud as a successful computing model that allows users and organizations to use external providers to store and process their data and make them available to others. Placement has appeared. Security is considered as one of the security challenges in the cloud. Guaranteeing security means guaranteeing reliability and not damaging data (data integrity) and providing services to legal users, in line with contracts with providers.

Cloud Computing is one of the popular techniques in distributed computing due to its ability to minimize the cost of computing when scalability and flexibility of computer process get increased. Cloud Computing provides shared resources and services via internet. Services are delivered through data center. Cloud Computing allows an interesting business proposal for IT industries to provide IT services without any extra investment. Client is able to perform heavy computer processes with low capable device (like mobile) which has resource to run the web browser. But cloud computing is crowded with many security related issues. When client saves his data to the company’s cloud, there may be chance of data breaching. So the purpose of this paper is to search out various issues in cloud computing where all computing is done on the server side and both data & tasks are stored on the data centers.
