Security Issues Of Cloud Computing Essay

Organizations use the Cloud in a variety of different service models (SaaS, PaaS, IaaS) and deployment models (Private, Public, Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers.In most cases, the provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information.

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):

Managing the security of an Electronic Medical Record (EMR) system in a cloud computing environment can be challenging. Even without the addition of the cloud computing environment, the EMR system is vulnerable to the compromise of login information, unauthorized viewing or editing of medical records, and denial of service attacks. First of all, the data contained within the Electronic Medical Record (EMR) itself is sensitive. Inside the structure of an EMR, one is potentially looking to find patient data that pertains to identity, billing information, dentistry, cardiology, dermatology, mental health, and physical attributes among other forms of data. In many EMR systems, tools to provide security and privacy are implemented. In these

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)

One of the main reasons to deliver security and privacy for the data in cloud computing is, as it utilizes distributed resources in an unsecured location or environment to allocate their services among people that belong to different organizations [1]. Enlargement in cloud adoption rates will result in increased computing security problems [2]. The greatest terror of cloud clients is that, most of the companies are not relaxed or comfortable accumulating their data and applications on systems that exists outside of their own assumed data centers [3]. Increased security of potential unwarranted approach and discovery to customer’s personal information is caused by relocating workloads to a distributed infrastructure. Data security and privacy protection issues are relevant to both hardware and software in the cloud architecture. This study is to review different security challenges and solutions for protecting data in the cloud and also aims at enhancing the data security and privacy protection for the trustworthy cloud environment. In this paper, we made a research analysis of an overview of security and privacy levels in secure provisioning and composition, about the interfaces which are been provided to user throughout the data storage and recovery and backup techniques which have been developed in the cloud p province where the data of the clients can be backed up[4]

In this article, we discuss about the different cloud types and models, threats and vulnerabilities of cloud, and how to manage them. The main aim of this literature review is to identify the weak points in cloud computing, minimize the threats and improve the security system. We will also discuss two of the main concepts of cloud – virtualization and multi-tenancy (Mishra, Mathur, Jain, & Rathore, 2013). A brief analysis of each of the threat and security measure is described in the literature review.

Cloud computing has become so famous; there is much widespread news about the cloud these days. This is mainly because of the exponential shift of the business applications from traditional models of software towards the Internet, and now through mobile devices. Cloud computing is a model that uses the network of remote servers that has been hosted on the internet rather than on a specific hardware. This would enable a better shared pool for storing, accessing and processing of data. With the huge information being available in the internet, the security for cloud computing has been challenging and this paper would elucidates the security threats of cloud computing also stating the possible countermeasures for them.

A significant paradigm shift is represented by public cloud computing from conventional norms of an organizational data center to a de-parameterized infrastructure which opens gates for potential adversaries to use. Cloud computing should be approached carefully with any emerging information technology area with due consideration to the sensitivity of data. A good planning helps and ensures that the computing environment is secure to the most possible extant and is in compliance with all relevant policies of an organization and makes sure the privacy is maintained.

The main issue that slows down the growth of cloud computing is security. No matter how many security management tools are released or assurances of reliability are made, complications with data privacy and data protection continue to plague the market. Covering all potential security issues in this article is simply impossible. This is because of the fact that we 're still discovering many of the security issues which challenges cloud computing as it is still a work-in-progress. Cloud Computing is rapidly evolving and hence what we see today may quickly become irrelevant.

Almost all kind of large and small organizations might face increasing number of attacks into their network or intellectual property. This may lead to data disclosure, data destruction, and damage of organization’s reputation. There are numerous threats in the cyber space which might be capable of stealing, destroying or making use of out sensitive data for financial and non-financial gains. As the amount of computer, mobile and internet users increases, so does the number of exploiters.

Users, resources, and the CLOUD should establish the trustful relationship among themselves. And they will be able to deal with the changing dynamically. The CLOUD includes distributed users and resource from distributed local systems or organizes, which have different security policies. According to this reason, how to build a suitable relationship among them is a challenge. In fact, the requirements for the security in cloud computing environment have some aspects, including confidentiality.

The ever growing need for the data in Information technology organizations has always lead to invent new services to meet the data needs, whether it is in the form of software, platform, hardware or storage. Cloud computing provides this services to organizations with cost effective methodologies like pay per service, network access, on-demand self-service. Organizations no more have to worry about storage overhead. This services has made huge impact on the organizations business process (Q. Wang, C.Wang, and Ren) (2011). At the same time with increase in technological services, the ever growing services are restricted due to security. Organizations use storage as a service to store their data remotely over cloud however the security of data is not guaranteed which leads to problems like data integrity, data availability, and data correctness. Various models has been proposed to address this data integrity concern over cloud (Chakraborty, Dhami, bansal), (2013).

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.

Cloud computing is a technology trend which is enabling and driving new markets in technology. Cloud computing refers to the idea of delivering personal (email, word processing, presentations, etc.) and business productivity applications (sales force automation, customer service, accounting, etc.) from centralized servers that share resources like storage, processing and bandwidth more efficiently by a cost factor of at least 5-10x. Cloud computing continues to garner a lot of industry buzz, but currently security and the cloud mix about as well as oil and water. There are many security challenges that enterprises face as they evaluate the agility, economics, and
