Data Security and Privacy Challenges in Cloud Computing
Cloud computing is the next generation paradigm in computation. Cloud computing environment makes it possible for the delivery of resources and application on demand over the internet. The cloud technology is made of software and hardware resources in the data centres with the capability of providing diverse services over the internet with the aim of satisfying the requirement of users. IT enables the ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. Cloud computing is essential in providing convenient on-demand network access to configurable computing resources that are shared. Configurable computing resources include various components such as virtual servers, network resources, software services, platforms and computing infrastructure. Cloud computing is a new computing archetype with the capability of providing services on demand at a minimal cost. There are three models of cloud computing model that include infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS).
The fact that the application of Information Technology (IT) consistently faces the problems of data security cannot be disputed. Data security has emerged to be one of the most significant barriers to the adoption of cloud computing technology. Data security involves various issues like trust, legal matters, compliance, and privacy. Data security is a serious concern since data in cloud computing are in different components such as servers, storage devices, smartphones, and wireless sensor networks.
Unlike the traditional information system, cloud computing has more complicated data security issues. Cloud computing can only be trustworthy if the security concerns of the users are rectified. A trustworthy environment is considered to be a key prerequisite for winning the confidence of the users to adopt cloud computing technology. The two most important factors that can facilitate the successful use of cloud computing are data protection and security. Although there are several techniques for data protection and security proposed by research studies, there is a need for further enhancement of techniques of data protection.
Cloud data security encompasses several aspects such as the availability of data, data protection, secure transmission of data, protection of data, and data location. Security challenges facing cloud computing are multi-tenancy issues, threats, external malicious attacks, disruption of services and the loss of data. Cloud computing requires the adoption of a robust data security framework. The three main potential threats to the adoption of cloud computing include security, privacy, and trust. Despite that fact that cloud computing is capable of saving an organization time and money, trusting the system is considered to be more important since it is handling data which is the real asset of an organization. The application of effective data protection and prevention techniques is crucial in trusting the entire cloud computing system.
Strategies for Addressing Data Security Issues in Cloud Computing
Tackling data security and privacy in cloud computing is vital in increasing the trust and confidence of users as well as leveraging the immense benefits associated with cloud solutions. The security, management, and monitoring of resources remain to be major issues in cloud computing. There is currently no standardized rules and regulation for deploying applications in the cloud. The establishment of standardized protocols in the cloud is crucial in boosting the integrity of the system. The dynamics of the cloud environment have rendered several novel techniques infective in ensuring total security of the cloud data. Privacy and security of data in cloud computing can be ensured by focusing on segregation of data, security of the cloud, and privacy protection. Addressing data security and privacy issues is essential in removing the barriers and hurdles that are hindering the rapid growth of cloud computing.
One of the easiest ways of stopping the implementation of a new technological solution is to raise security red flag. A project can come to a halt once security concerns have been raised around a new IT solution. As cloud infrastructure and computing become common in enterprise IT one of the biggest hurdles to its adoption revolves around the security of the cloud. The creation of a security strategy plan is considered to be essential for enterprise IT organizations. The first essential step in the adoption of cloud computing is partnering with a service provider that has a strong security capability. The organization should take an active role in ensuring the security and management of risk. The enterprise resources of the organization can be secured using seven basic steps that provide a proven methodology for realizing cost-effective security and privacy of data and information. Appropriate execution of the procedures can enable the organization to gain the cost and business advantages associated with cloud computing without compromising the security of enterprise applications.
The first step is reviewing the objectives of the organization. It is essential for loud security plans to start with a basic understanding of business goals. The focus of security is to enable people, technologies and processes. Gaining executive input is vital in ensuring the protection of assets with proper safeguard. It also ensures that all parties have a good understanding of the strategic goals.
The second step is maintaining a risk management program. The program should be developed centrally and viewed holistically. The establishment of a risk management program in cloud computing is essential in the reduction of the overall risks to the organization. It is also useful in the prioritization and utilization of resources as well as the provision of a long0term strategy to a business.
The third step is the creation of a security plan that supports the objectives of the organization. It is vital to establish an objective with measurable outcomes. The goals should be capable of supporting the growth and stability of the organization. These goals should comprise of the following: specific date of completion, measurable expected outcome, and verification of achievements. Careful analysis needs to be conducted by security professionals. Necessary controls and auditing capabilities should also be performed by security personnel with the aim of mitigating threats and maintaining a reasonable security program that can offer protection to the assets of the organization.
The fourth procedure is the establishment of corporate-wide support. The establishment of the levels of security that are capable of meeting the objective of the organization as well as complying with the policies if risk management and regulatory requirements are very vital. The organization should focus on establishing centrally managed security measures that can be implemented efficiently across the organization without any significant effect on productivity.
