Cloud Computing Essay

The security concerns for IaaS and PaaS models are described collectively because of their reliance over each other. The attacks on these two layers are of three types: attacks on the cloud services, attacks on virtualization and attacks on utility computing. Hardware virtualization, software virtualization, cloud software, utilitycomputing and Service Level Agreement (SLA) are considered some of the common security concerns for IaaS and PaaS.

Cloud computing security or, more simply, cloud security is an evolving sub-domain of computer security, network security, and, more broadly, information security. It refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing.

Cloud computing is vast and so are the security threats. When a company opts for cloud computing, it will consider the advantages, but some of the companies fail to consider the vulnerabilities that might lead to data lost and misuse.

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.

Most of us have been heard about the most cloud security failures in which all the cloud technology companies are continued to mature, they still suffer the same type of issues in-house infrastructure’s. Cloud computing has become a biggest market in today’s technology. In a report of 2016, analysts at Gartner predicted that transferring to cloud is going to affect $1 Trillion in Information technology in the next five years. Cloud services market has grown to an extent level that it was not a notable percentage of total it is spending, which was helping to generate new technologies and start-ups which are born in the cloud. When cloud services are going offline or software and websites will fail it can always results in huge business

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 high regard to cloud computing is on the rise due to its ability to improve flexibility, expand access to data, and lower costs. Cloud computing discharges organizations from requiring their hardware and software infrastructure to be acquired and maintained (Leavitt et al., 2009). On the other hand, while there is much noise being made about the benefits of cloud computing, questions have been brought up with respect to whether cloud computing is safe especially when it comes to its privacy, security, and reliability. The purpose of this paper is to discuss the different general controls and audit approaches for software and architecture, cloud computing, service-oriented architecture, and virtualization. This paper gives a summary analysis of the recent research that is available. Additionally, risks and vulnerabilities associated with public clouds, private clouds, and hybrids have also been researched. Within the research conducted, there are important examples provided. Recommendations are shown on how organizations could implement and mitigate these risks and vulnerabilities. This paper even outlines a list of IT audit tasks that focuses on a cloud computing environment due to the results of the analysis, the risks and vulnerabilities, and the mitigation controls.

This journal examines the various types of threats that a cloud-based company has to defend against. The authors recognize that the cloud has the potential to be a disruptive force in technology, and it examines the concerns that a business has for migrating to the cloud through the use of surveys. The benefits and risks are examined and the article provides statics and charts to illustrate the findings. The most interesting point of this article is it highlights the concerns customers have listing security as the number one reason preventing a business from migrating to the cloud. I plan to use this article to explain the challenges developers face in securing data on the cloud, not only with application development but also with educating businesses to alleviate misconceptions on cloud computing.

Security is additionally one of the significant worries of the cloud computing innovation and is evident through the prior investigations. There exist a few dangers included which will limit the organizations in partaking and actualizing these cool administrations. There exist significant odds of dangers like losing of information, information ruptures, in security to the secret information which can affect the organizations. In this manner, the vast majority of the organizations introduce in the market fears to render their private information helpless against the uncertainties of unapproved access and they were in that by embracing the cloud benefits, their information might be more presented to dangers and likely of getting assaulted or

Everyone has an opinion on what is cloud computing. It can be the ability to rent a server or a thousand servers. It can be the ability to rent a virtual server, load software on it, turn it on and off at will. It can be storing and securing large amounts of data that is accessible only by authorized applications and users.

Cloud services: The organizations have been highly dependent on the cloud services. The cybercriminals have been seeking ways to exploit corporate security policies for protecting cloud services. The cloud services have been providing immense risk of data being disclosed deliberately or accidentally. The hosting companies have a greater ease of control over the private data and information and can even communicate between the end user and access his user data even without his permission. Therefore this threat has to be placed at the highest priority. Additionally, the cloud providers have the authority to the share information with any of the third parties even without any warrant. All these activities poses privacy concerns as the data can be access on the cloud anywhere and anytime where the information can be deleted, or even altered. All these activities have further left a room for potential unwanted disclosure of data and information on the cloud. Thus using cloud services in an organization poses a threat to exploitation and stealing of confidential data by their competitors, cybercriminals and vigilante justice seekers (Shaikh, F. B., & Haider, S., 2011).

Security is the most prioritized aspect for any form of computing, making it an obvious expectation that security issues are crucial for cloud environment as well. As the cloud computing approach could be associated with having users’ sensitive data stored both at clients’ end as well as in cloud servers, identity management and authentication are very crucial in cloud computing. Verification of eligible users’ credentials and protecting such credentials are part of main security issues in the cloud - violation in these areas could lead to undetected security breach at least to some extent for some period. A possible authentication scenario for a cloud infrastructure is illustrated in figure 4.

However, with all the benefits, the rapid development of information and communication technology (ICT) involves certain security challenges as well. The associated challenges and issues of Cloud computing must be considered prior to the ubiquitous adoption of the technology [2]. The paper presents the analysis of the cloud computing model in terms of the deployment of its service models, along with the security issues associated with it. The paper also presents the possible techniques of eliminating the security concerns of the cloud computing.

When we speak cloud computing, we are about multi-tenancy and a server host; so, the service is always never really owned by clients who want to rent it. All cloud computing(CC) platforms and infrastructures-as-service operates on a

Cloud computing is a shared resource that holds valuable data from masses of people and organisations and is therefore an easy target for hackers. Security within cloud computing involves a set of control-based technologies, polices, processes and standards to protect information, data applications and infrastructures related to cloud computing usage. Security within this area addresses the physical and logical security issues across the different service models as well as how these services are delivered ie.via the public, private or hybrid model. There are many points of entry for an attacker in the cloud environment and people are more exposed to data breaches than they think e.g. using an insecure website on your mobile phone or if a database administrator shares a password, personal details can be accessed.
