Upgrade-Data Security in Cloud by Machine Learning and Cryptography Techniques

The term cloud computing is referred as the shared pool of customizable computer resources and high quantity services which can easily be provisioned with less management endeavours via internet. It transfigured the mode associations reach IT, which enables them to be more perceptive, launch new business models, and minimise the IT costs. These technologies are to be administrated in an interdisciplinary collection of architectures, characterized into various deployment and service models, and can synchronize with other related technologies. The widespread issues with cloud computing are security, reliability, data privacy and anonymity. Cloud computing provides a way to share distributed sources and services that are owned by different organizations or sites. Since it shares distributed resources via network in open environment that results in security issues. In this paper, our aim is to upgrade the security of data in the cloud and also to annihilate the difficulties related to the data security with encipher algorithm. In our proposed plan, some key services of security like authentication and cryptographic techniques are assigned in cloud computing environment.

Drivers for IWMS implementation in real estate management

PurposeIT platforms such as integrated workplace management system (IWMS) gain higher importance in real estate management, but there is a lack of knowledge on what IWMS is and what the drivers are for its implementation in real estate organisations. The paper aims to provide knowledge on this.Design/methodology/approachThe research combines theories of real estate management, IT implementations and change management, with a qualitative case study of IWMS implementation in a public real estate organisation in Denmark. The research data consist of customer surveys, document studies, semi-structured interviews and in-depth analysis of IWMS features.FindingsThe paper identifies several drivers for IWMS implementation, such as data standardisation, validation and easier data exchange, business process optimisation, decrease in IT costs and improved customer service. Furthermore, the case study reveals that the IWMS implementation is not considered as a definite IT project but as an organisational change project impacting the entire organisation.Originality/valueThere has so far not been any public real estate organisations in Denmark using IWMS, and the knowledge about IWMS in public real estate sector is therefore limited. To date, no one has analysed what the drivers are for IWMS implementation in real estate organisations. This research paper brings new knowledge on IWMS and presents drivers for IWMS implementation, observed from an implementation process in a public real estate organisation.

СУЧАСНІ ТЕНДЕНЦІЇ РОЗВИТКУ ІТ-ІНДУСТРІЇ В УКРАЇНІ І СВІТІ

The article considers the current state of the domestic information technology industry. It is shown that the domestic market of information technologies is at the stage of active formation. The key factors for the development of the IT sector are: qualified personnel; building world-class technology infrastructure; open transparent economy; active participation of the state in achieving a balance between the development of technologies and the creation of conditions for the functioning of the market.The trends that have been observed in the IT market in recent years in Ukraine and the world have been studied. Exports of software and IT services are increasing annually, as is the size of the IT industry market. The leader in the ranking of global competitiveness of the IT industry are the United States. The top five countries include Japan, South Korea and Australia, and the UK heads the list of European countries in front of Sweden and Denmark.Ukraine is a country with high technological potential, which contributes to the development of the IT industry. However, in the ranking of the level of IT costs and dependence on this level of economic development, Ukraine occupies one of the last places. The low level of IT consumption in Ukraine is both a consequence and a reason for the low level of economic well-being.The factors constraining the development of the IT sector are identified. These include the low availability of state-of-the-art technologies, the low level of government procurement of goods and services in the IT sector, high tax rates, ineffective promotion of the IT sector in the international arena, and low levels of protection of intellectual property rights.Established the main obstacles on the part of the state and proposed ways to address them. It was noted that the state should become a major player in the development of a promising IT industry. It is necessary to form a state strategy of interaction with the IT sector. Transparency of business, reducing corruption will affect the international image of Ukraine and the flow of investment.

Can information technology help hospital employees to reduce costs?

ObjectivesThe purpose of this study is to examine the association of hospital employees and health IT on Case Mix Index (CMI). MethodsThe California's hospitals observed for three consecutive years were included. Following a review of the available data, there were 180 hospitals selected from the surveys for three years from 2008 to 2010, for a total of 540 hospital observations. To examine the association of hospital employees and health IT on CMI, a generalized estimation equation (GEE) with log link and normal distribution was employed. Staffing (full-/part- time), hospital and market characteristics (hospital ownership, teaching status, network hospital status, competition and number of licensed beds), volume of hospital service (percentage of Medicare and Medicaid, total admissions, outpatient visits, emergency visits, and number of inpatient and outpatient surgeries) were controlled. ResultsIt has three important findings. First, IT use was positively associated with CMI value. Second, the number of PTEs was positively associated with CMI value. Third, the interaction between IT and PTEs was negatively associated with CMI value. ConclusionsThe negative association between CMI value and the interaction of PTEs with IT cost implies that the use of IT systems may reduce some of the productive efforts of PTEs through DRG up-coding.

Cloud Computing: An Analysis on Round Robin Technique

Cloud computing (CC) performs calculation over a collective and huge group of resources for the dispersed environment. It calculates the resources using applications, processing power, storage etc. As its practical use in the day to day life, it grabs much more attention for the research in academic and industry. CC gives various advantages, including lessened IT costs, adaptability, expanded collaboration, and so forth. Nonetheless, the approach of CC has represented an assortment of new difficulties for both cloud clients and cloud specialist sources. With increasing attentiveness and apprehensions considers to CC and Information Security, there is increasing awareness and practice of Security Algorithms into procedures and Systems of records. As recognized by study, numerous of the concerns dealing with the CC want to be resolved immediately. The industry has prepared important progresses in reducing threats to CC, but there is additional to be done to attain a level of maturity that presently exists with conventional/on-premise hosting.

GraphBAD: A general technique for anomaly detection in security information and event management

SummaryThe reliance on expert knowledge—required for analysing security logs and performing security audits—has created an unhealthy balance, where many computer users are not able to correctly audit their security configurations and react to potential security threats. The decreasing cost of IT and the increasing use of technology in domestic life are exacerbating this problem, where small companies and home IT users are not able to afford the price of experts for auditing their system configuration. In this paper, we present GraphBAD, a graph‐based analysis tool that is able to analyse security configurations in order to identify anomalies that could lead to potential security risks. GraphBAD, which does not require any prior domain knowledge, generates graph‐based models from security configuration data and, by analysing such models, is able to propose mitigation plans that can help computer users in increasing the security of their systems. A large experimental analysis, conducted on both publicly available (the well‐known KDD dataset) and synthetically generated testing sets (file system permissions), demonstrates the ability of GraphBAD in correctly identifying security configuration anomalies and suggesting appropriate mitigation plans.

Multi-users Coordinated Sharing Grid Resource Management System

The fundamental task of grid resource management system is to supply on-demand resources service for various users and applications by aggregate heterogeneous, dynamic and increase resource. Most current grid resource management system is exclusive which brings two sides of deficiency distinctively. We bring forward and realize a multi-user coordinated sharing resource management system, which is a utility oriented resource management system to support resources sharing by multi users or multi workload schedulers, thus extendable resource serving capability can be improved. When the system is used in an “intelligent building” and “intelligent community”, the IT cost of the community enterprises can be reduced significantly.

Ontology for Semantic Data Integration in the Domain of IT Benchmarking

A domain-specific ontology for IT benchmarking has been developed to bridge the gap between a systematic characterization of IT services and their data-based valuation. Since information is generally collected during a benchmark exercise using questionnaires on a broad range of topics, such as employee costs, software licensing costs, and quantities of hardware, it is commonly stored as natural language text; thus, this information is stored in an intrinsically unstructured form. Although these data form the basis for identifying potentials for IT cost reductions, neither a uniform description of any measured parameters nor the relationship between such parameters exists. Hence, this work proposes an ontology for the domain of IT benchmarking, available at https://w3id.org/bmontology. The design of this ontology is based on requirements mainly elicited from a domain analysis, which considers analyzing documents and interviews with representatives from Small- and Medium-Sized Enterprises and Information and Communications Technology companies over the last eight years. The development of the ontology and its main concepts is described in detail (i.e., the conceptualization of benchmarking events, questionnaires, IT services, indicators and their values) together with its alignment with the DOLCE-UltraLite foundational ontology.

Achieving IT‐based synergies through regulation‐oriented and consensus‐oriented IT governance capabilities

AbstractThis study aims at exploring the IT governance capabilities that enable organizations to achieve IT‐based synergies. Following existing work on the contextualization of theories and drawing on the resource‐based view of the firm (RBV), we develop an RBV of IT‐based synergies in two steps. First, we adopt existing context‐specific constructs and relationships from prior work on IT governance capabilities, IT relatedness, and synergies to develop a preliminary contextualization of the RBV. Second, to further refine our theoretical framework, we conduct an exploratory field study that includes interviews with 26 CIOs and other IT executives from 21 multibusiness firms. Our findings suggest that IT governance capabilities lead to IT‐based synergies through IT relatedness and business process relatedness. We found regulation‐oriented IT governance capabilities (IT roles and IT processes) to increase IT relatedness, while consensus‐oriented IT governance capabilities (IT groups and relational capabilities) had a positive effect on business process relatedness. Our results suggest that, in isolation, IT and business process relatedness lead to IT cost synergies, while collectively enabling IT‐induced business synergies. Our study is among the first to treat IT relatedness as an endogenous construct and to explicitly integrate business process relatedness into the IT governance domain. Our context‐specific decomposition of IT governance capabilities helps to better explain their links to IT and business process relatedness. These findings contribute to a better understanding of the tension between IT‐based synergies and business‐IT alignment. Decision‐makers are guided in developing IT governance capabilities to achieve IT‐based synergies.

2017 ACR Annual Meeting Open-Microphone Session: Navigating the Landscape of Changing Practice Models: Private Practice, Corporate Radiology, and Enterprise Systems

Many practice groups are considering adopting new practice models, primarily to secure their practices by adapting to new payment models, government compliance and regulation, and increasing IT and infrastructure costs. As we move toward value-based care and capitation, the value equation (value = quality/cost) will lead us to also compete on cost to improve value. No matter what payment models ultimately dominate, we need to be prepared to lead in a value-based care environment. Measures of value will either be defined by radiologists or imposed by outside entities. It is critical to our continued success that practices and practice leaders continue to fully and strongly support the ACR to avoid the possibility of a decline in membership that may accompany a lack of practice engagement. Consolidation appears inevitable, but with the help of the ACR, radiologists should have a vibrant future if investments are made now in determining appropriate radiology-specific value measures that are meaningful in consolidated health care environments.

Clouds are Forming Around the Upstream Sector, and That’s a Good Thing

The oil and gas business knows that it is on the slow track when it comes to leveraging many of the latest digital technologies. However, this may be a bit of an overstatement when discussing the influence of cloud computing—which allows businesses to crunch data faster than ever before thanks to a nearly unlimited ability to scale up processing power. Fatima Alsubhi is the chief executive officer of Certis Information Services, a Houston-based information management firm that has helped some of the biggest names in the oil field transition their data and files into the cloud. That experience tells her that cloud platforms are well on their way to becoming the norm in the upstream business, comparable to how advanced oilfield software became mainstream years ago. “If someone says they increased reliability by 10%, you know part of that is because of the use of software—and now it’s the same thing happening with the cloud,” she explained, adding that the early adopters no longer see cloud services as simply rented server space. The growing consensus is that cloud platforms combined with software-as-a-service represent a powerful data tool, the limits of which have only begun to be tested. “This is going to evolve and keep moving forward because it just makes sense,” emphasized Alsubhi. “The cloud is cheaper, it’s faster, and it’s easier.” Plenty of others appear to be in agreement. Take for instance just a few news items from July including an announcement that BP is transferring proprietary information out of its own data centers and into Microsoft’s Azure cloud-based analytics processing platform. The shift is notable because it represents the latest step in BP’s strategy to shutter its on-premises data centers and fully embrace public cloud platforms. At a recent conference the company said the effort has already cut its IT costs by around 40%. Also in July, ConocoPhillips made clear its feelings about cloud technology by appointing the founder of a cloud-based analytics company to its board of directors. Around the same time, Amazon Web Services noted in a press release that Halliburton’s Landmark software product line is among the earliest users of its newest cloud product built to support intensive 3D visualizations and virtual reality applications. These examples all highlight how big oil is warming to the biggest players in cloud technology. But because the cloud market is growing at a far faster rate than traditional IT spend, more small and medium-sized oil and gas producers are expected to begin following suit.

A Holistic Decision Framework to Avoid Vendor Lock-in for Cloud SaaS Migration

Cloud computing offers an innovative business model to enterprise for IT services consumption and delivery. Software as a Service (SaaS) is one of the cloud offerings that attract organisations as a potential solution in reducing their IT cost. However, the vast diversity among the available cloud SaaS services makes it difficult for customers to decide whose vendor services to use or even to determine a valid basis for their selections. Moreover, this variety of cloud SaaS services has led to proprietary architectures and technologies being used by cloud vendors, increasing the risk of vendor lock-in for customers. Therefore, when enterprises interact with SaaS providers within the purview of the current cloud marketplace, they often encounter significant lock-in challenges to migrating and interconnecting cloud. Hence, the complexity and variety of cloud SaaS service offerings makes it imperative for businesses to use a clear and well understood decision process to procure, migrate and/or discontinue cloud services. To date, the expertise and technological solutions to simplify such transition and facilitate good decision making to avoid lock-in risks in the cloud are limited. Besides, little investigation has been carried out to provide a comprehensive decision framework to support enterprises on how to avoid lock-in risks when selecting and implementing cloud-based SaaS solutions within existing environments. Such decision framework is important to reduce complexity and variations in implementation patterns on the cloud provider side, while at the same time minimising potential switching cost for enterprises by resolving integration issues with existing IT infrastructures. This paper proposes a holistic 6-step decision framework that enables an enterprise to assess its current IT landscape for potential SaaS replacement, and provides effective strategies to mitigate vendor lock-in risks in cloud (SaaS) migration. The framework follows research findings and addresses the core requirements for choosing vendor-neutral interoperable and portable cloud services without the fear of vendor lock-in, and architectural decisions for secure SaaS migration. Therefore, the results of this research can help IT managers have a safe and effective migration to cloud computing SaaS environment.

Strategic management in the IT department

Alexander N. Biryukov - Associate Professor, Department of Business Informatics, Financial University under the Government of the Russian FederationAddress: 49, Leningradskiy Prospect, Moscow, 125993, Russian Federation E-mail: anbiryukov@fa.ru This paper describes a new approach to strategic management in IT departments as compared with the existing approach, traditionally based on the development of an IT strategy aligned with the enterprise’s business strategy. The proposed method assumes gaining greater trust from the business to be the principal goal of an IT department. Meanwhile, all the other goals are treated as implications of the trust, because none of them can be achieved if the IT department is not considered a trusted partner by the business management. Trust in the IT department is an aggregate of individual trust exhibited by its customers, some of which are interrelated and mutually affect their opinions. To obtain maximal personal trust, the IT department should apply an individual approach to each of its customers. In terms of IT Service Management (ITSM), this means that an individual Service Level Agreement (SLA) should be designed and used with respect to each customer. As a result, the IT Department will be able to gain the maximal integral trust. The IT Department can benefit from the acquired trust for different purposes. For example, the IT Department can use the increasing customer trust to justify modifications of SLA conditions so as to reduce IT costs without affecting the customer. Another way is using the integral trust to guarantee support of the corporate management when the IT Department starts some innovative undertaking in its own field. In the conclusion, it is shown that the problem of maximizing integral trust is not easier than the well-known knapsack problem.

Comparative Study of Traditional Database and Cloud Computing Database

This paper gives a comparative analysis of latest technology called “Cloud Computing database ” or “database-as-a-service”(DBaaS) called Relational Cloud which is causing a major shift in the Information Technology industry with the traditional databases Realtional Database Management System which have been used since many years .Cloud Computing is a new technology which has been developed to virtualize IT systems and to access the needed applications on the Internet, through web based applications. This means no IT costs for hardware or servers. As compared to the traditional way of building an IT environment is to buy servers, hardware, licenses and to install the software. This is a long and costly process, involving many infrastructure demands and long deployment cycles. This fully IT internal model may be commonplace, but IT as we know it today is being replaced by newer technologies.

Cloud Computing in Education in Developing Countries

The main advantage of cloud computing is to reduce the IT cost. By using cloud computing, organisations do not have to set up an IT infrastructure, and instead are able to rent resources and give payment only for the using services. Even with the appealing of cloud computing benefits, it is still in infancy in developing countries due to many reasons. Technology adoption has been explored to a limited degree in developing countries, particularly in relation to cloud computing in the tertiary education sector. Existing studies have examined technology adoption in developed countries and to a lesser extent in developing countries in non-education contexts such as e-government. This paper contributes to the cloud computing adoption literature in developing countries, and specifically in Saudi Arabian universities.
