Key Point: As security professionals, our work is cut out for us. Cloud Computing Security Issues Randy Marchany, VA Tech IT Security, marchany@vt.edu. The major issues in cloud computing can be outlined as: Secure storage of data; The security of the stored data is a primary concern. Before deploying a particular resource to cloud, one should need to analyze several aspects of the resource such as: Select resource that needs to move to the cloud and analyze its sensitivity to risk. Since all the data is transferred using Internet, data security is of major concern in the cloud. All of the service models should incorporate security mechanism operating in all above-mentioned areas. From the consumers' perspective, cloud computing security concerns, especially data security and privacy protection issues, remain the primary inhibitor for adoption of cloud computing services. Along with purchase cost, off-site hardware cuts internal power costs and saves space. 8. Understand the cloud service provider's system about data storage and its transfer into and out of the cloud. Some most common Security Risks of Cloud Computing are given below-Data Loss. Security: Many cloud vendors offer a broad set of policies, technologies, and controls that strengthen our data security. To identify the security challenges those are expected in the future of Cloud Computing. 50% of cybersecurity professionals strongly agree or agree with the statement: It is difficult to audit network security controls associated with cloud computing infrastructure. Distributed Denial of Service– a DDoS attack attempts to knock a resource offline by flooding it with too much traffic. To restrict client from accessing the shared data directly, proxy and brokerage services should be employed. The march of cloud computing is unstoppable. All of the above steps are shown in the following diagram: Encryption helps to protect data from being compromised. The proxy forwards the request to the broker. In this approach, two services are created: A broker with full access to storage but no access to client. [4] illustrates the unique issues of security and privacy challenges with cloud whereas Minqi Zhou et al. Cloud computing configurations provide computer-based resources and outsourcing mechanisms that enable different services for different users, such as application-based systems. IaaS provides the infrastructure, PaaS provides platform development environment, and SaaS provides operating environment. There are numerous legal issues in cloud computing like operational, legislative or regulatory, security, third party contractual limitations, risk allocation or mitigation, and jurisdictional issues. 2. RELATED WORK Hasan Tabaki et al. With Wycore, people can securely access their data and programs on any device of their choice at anytime, anywhere. Consider the cloud type to be used such as public, private, community or hybrid. Although each service model has security mechanism, the security needs also depend upon where these services are located, in private, public, hybrid or community cloud. II. Shared Technology Issues Lead Research Scientist CERT Enterprise Threat and Vulnerability Management Team . Cloud Computing Issues & Challenges – Cloud computing is a common term you hear about on and off. However, it is not yet made possible because each of the cloud provider uses different standard languages for their platforms. Something Old, Something New •New: Cloud describes the use of a collection of services, applications, information, and infrastructure comprised of pools of compute, network, information and … These aspects of cloud computing are: (i) The illusion of infinite computing resources available on demand, thereby eliminating the need for cloud computing users to … It means the application on one platform should be able to incorporate services from the other platforms. Data intensive applications on cloud requires high network bandwidth, which results in high cost. Security issues is one of the biggest concerns that has been affecting the growth of cloud computing .It adds complications with data privacy and data protection continues to affect the market. The Cloud Security Alliance works to promote the use of best practices for providing security assurance within Cloud Computing, and provide education on the uses of Cloud Computing to help secure all other forms of computing. By and large, cloud computing is a very secure technology, offering organisations plenty of options for protecting their sensitive data. 3. [24] examined cloud security and privacy issues in As companies begin to move data to the cloud, they have to implement policies and procedures that will enable their employees to take advantage of cloud computing without affecting the security of corporate data. 3. Low bandwidth does not meet the desired computing performance of cloud application. Shared responsibility for security between cloud providers and their customers. Data in cloud should be stored in encrypted form. Whether a lack of visibility to data, inability to control data, or theft of data in the cloud, most issues come back to the data customers put in the cloud. Among all the cloud security risks, cloud data privacy seem to concern the cloud users the most since businesses always have the risk to lose its reputation and trust because of data leakage. Introduction New computing era, the concept of cloud computing become more popular because of his cost and elasticity. Finally the proxy sends the data to the client. Covers topics like Introduction, Planning of security, Security Boundaries, Data security in cloud, etc. To suggest some counter measures for the future challenges to be faced in Cloud Computing. Most cloud computing security risks are related to cloud data security. And professionals use it without even knowing about the actual concept. IaaS has the least level of integrated functionalities and integrated security while SaaS has the most. It is necessary for cloud systems to be reliable and robust because most of the businesses are now becoming dependent on services provided by third-party. Select resource that needs to move to the cloud and analyze its sensitivity to risk. If this is achieved, the data being transmitted can be altered. In figure 2 we can see the five main areas of concern for a cloud service provider when it comes to security. Cloud computing, an emergent technology, has placed many challenges in different aspects of data and information handling. Account or Service Traffic Hij… Cloud computing is bringing amazing advantages and benefits companies. The risk in cloud deployment mainly depends upon the service models and cloud types. But data breaches have existed in all different forms for years. Similar point. Man in the Middle attacks– where a third party manages to become a relay of data between a source and a destination. Some of these are: 1. Portability This is another challenge to cloud computing that applications should easily be migrated from one cloud provider to another.
