The purpose of making this report is to build an understanding and perspective about updates in information security and for building generic skills. In field of information technology various current developments have seen and these are booming this industry. For users, there are various new technologies available that can help them in their personal and official works. With the advancement of technologies, risks for security and privacy are also found in usage of technologies. The main emphasizing factor of this report is regarding Security and Privacy Issues in Cloud Computing. Cloud Computing is so much popular worldwide for its security, reliability and easiness to access remote databases. In online businesses i.e. e-commerce, cloud computing has provided big contribution. Basically cloud computing is considered better to host services over the internet. (SearchCloudComputing, 2016)
Cloud Computing is a wide concept to discuss. Cloud computing provides various benefits to its users that include on-demand service, resistance and user can pay for this service according to their consumption. Private, Public and Hybrid types of services are provided by cloud computing to its users. Besides these benefits of this technology, some issues of security and privacy are found in it and it is important to emphasize on those issues.
According to analysis about this cloud computing, some essential challenges and issues of cloud computing are found and these issues and challenges are discussed as below:
Security and Privacy
This is major concerning issue of cloud computing that how security and privacy of data can be maintained. Business information is so much confidential and cloud service providers must provide security to its users regarding security and privacy of information. The network attacks like hacking and phishing would affect cloud infrastructure and multiple clients who are based on that infrastructure. This kind of issues should be mitigated as soon as possible. (Klostermann, 2012)
Delivery and Selling of Services
In case of on-demand service of cloud computing, it is difficult to evaluate actual cost of these services. Until cloud service provider will not have good and comparable benchmarks till then proper budgeting and assessment of cost is difficult in case of cloud services. Service-Level-Agreement (SLAs) of the cloud providers do not provide guarantee for the availability and scalability for service. It is possible that businesses will be reluctant to switch to cloud without a strong service quality guarantee.
Availability and Reliability
Some problems are found in availability of cloud services. Cloud providers are accountable to identify that all users are getting their services properly or not. For doing this, provider should use internal and third party tools. It is vital to have plans for supervising usage of services, SLAs Performance and Business Dependency of Services.
Cost of Bandwidth and Performance
It is possible for businesses to save money on hardware, but they cannot spend more for the bandwidth. It is right that cost of bandwidth is low for small cloud based applications, but in case data-intensive applications, cost rate is high. For delivering intensive and complex data requires high bandwidth. That is why businesses have to wait for reduction in cost before switching to the cloud.
These above listed challenges must be taken into consideration by cloud providers and must find out mitigations for this. Next segment of this report describes relevant technologies for security and privacy of cloud computing.
Security issues of cloud computing must be mitigated by cloud providers that are big barriers in security of cloud computing. There are various relevant technologies available that can be used for maintaining security and privacy of cloud computing. Here are some tools that can be used for maintaining security and privacy of cloud services.
It is responsibility of cloud providers to ensure already existed effective governance, risk and compliance processes to control security violation.
Next tool that can be used for security and privacy of cloud computing is to understand importance of auditing the agreement of IT systems that provides hosting for applications and data. It is necessary to ensure that it is compliance with their corporate and policies of government and industry. (AlZain, M, 2012)
Understanding of internal cloud environment of cloud service provider is also necessary, so that customers can ensure that this environment is according to their requirements or not.
Proper assurance of the facilities for management and control of cloud services.
The technologies or tools that are discussed above for maintaining security and privacy of data, have wide application areas in web services. Not only to secure cloud applications but also other internet based services use above discussed tools for maintaining high level of security. As we know knowledge about security policies and understanding about security audits are required, in every case of security and privacy.
Over the years the word “Cloud” in IT industry has become a vague and flexible term and it does not reference anything in particular. Due to this vague meaning of cloud, some people take advantage of this and provide any other services as cloud. Those people make fool of cloud users. So it is necessary to clear meaning of cloud in IT. Cloud in IT industry consists of remote delivery, eliminates need for on-site facilities, load balancing and multi-tenancy.
For this report, some forums about issues of cloud computing are analyzed and in those forums issues about management of large scale cloud computing and management of security of cloud users are discussed in detail. On the behalf of this discussion in forums, we can say that, our summary report provides information about these questions in detail. In this report, important concepts are issues and challenges of cloud computing, relevant technologies for this and clarification about vague statement of cloud. So users can get accurate answers for their queries.
There is one important issue about management of large scale of cloud computing is not discussed. This is a weak point of this report. This information is necessary for those people who use cloud services at large scale. This issue is important because in future, cloud services will be used at large scale and its management will become priority for cloud providers. (Career.guru99.com, 2016)
In this report, some important issues of cloud are discussed. The major impact of these cloud issues on real world is that they may not get appropriate and quality services from cloud providers. Due to improper security of confidential information on cloud platform, heavy loss of information can occur. That is why, security and privacy is essential.
Cloud technology is a useful approach to IT users who want secure access of information from remote database and on-demand services. But while adapting cloud services, awareness about implementation of this technology is necessary for users. Besides this, users must have clarification about vague statement of cloud. These are some important factors that must be considered before implementation of cloud computing both at large and small scale businesses.
