As consequence, a large mount of knowledge is being produced. This causes the problem of efficient knowledge management and mining. The main aim is to develop DM infrastructures to fully exploit the benefit of the knowledge contained in these very large data repositories. To this end, we introduced ”knowledge map” approach to represent easily and efficiently the knowledge mined in a large-scale platform such as Grid. This also facilitates the integration and coordination of local mining processes along with existing knowledge to increase the accuracy of the final models. In this paper, we discuss its advantages and its design issues.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123377629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Next Generation Cloud Computing Architecture: Enabling Real-Time Dynamism for Shared Distributed Physical Infrastructure","authors":"V. Sarathy, P. Narayan, Rao V. Mikkilineni","doi":"10.1109/WETICE.2010.14","DOIUrl":"https://doi.org/10.1109/WETICE.2010.14","url":null,"abstract":"Cloud computing is fundamentally altering the expectations for how and when computing, storage and networking resources should be allocated, managed and consumed. End-users are increasingly sensitive to the latency of services they consume. Service Developers want the Service Providers to ensure or provide the capability to dynamically allocate and manage resources in response to changing demand patterns in real-time. Ultimately, Service Providers are under pressure to architect their infrastructure to enable real-time end-to-end visibility and dynamic resource management with fine grained control to reduce total cost of ownership while also improving agility. The current approaches to enabling real-time, dynamic infrastructure are inadequate, expensive and not scalable to support consumer mass-market requirements. Over time, the server-centric infrastructure management systems have evolved to become a complex tangle of layered systems designed to automate systems administration functions that are knowledge and labor intensive. This expensive and non-real time paradigm is ill suited for a world where customers are demanding communication, collaboration and commerce at the speed of light. Thanks to hardware assisted virtualization, and the resulting decoupling of infrastructure and application management, it is now possible to provide dynamic visibility and control of services management to meet the rapidly growing demand for cloud-based services. What is needed is a rethinking of the underlying operating system and management infrastructure to accommodate the ongoing transformation of the data center from the traditional server-centric architecture model to a cloud or network-centric model. This paper proposes and describes a reference model for a network-centric datacenter infrastructure management stack that borrows and applies key concepts that have enabled dynamism, scalability, reliability and security in the telecom industry, to the computing industry. Finally, the paper will describe a proof-of-concept system that was implemented to demonstrate how dynamic resource management can be implemented to enable real-time service assurance for network centric datacenter architecture.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123624969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Importance of Corporate Forensic Readiness in the Information Security Framework","authors":"G. Pangalos, C. Ilioudis, I. Pagkalos","doi":"10.1109/WETICE.2010.57","DOIUrl":"https://doi.org/10.1109/WETICE.2010.57","url":null,"abstract":"Corporate forensics is rapidly becoming an essential component of modern business. Having no a priori knowledge on whether a security related event or corporate policy violation will lead to litigation, it is argued in this paper that digital forensics principles need to be applied to all corporate investigatory, monitoring and auditing activities. Corporate forensics are also necessary in modern organizations in order to credibly investigate what and how it happened, what part of the security policy was breached, whether existing corporate security mechanisms are sufficient and responding promptly, help investigate the impact and costs of a security incident, help management take well documented actions, and so forth. Forensic practices are therefore departing fast from the niche of law enforcement and becoming a business function and infrastructural component. This migration poses new challenges to security professionals that must be resolved. Furthermore, protecting information and information assets solely through technical means and security procedures is also no longer sufficient in modern corporate environments, as accountability from management is also needed. Forensic readiness helps enhance the security strategy of an organization, reduce the impact of a security incident and provide management with the means to demonstrate that reasonable care has been taken to protect information resources. Forensic readiness is becoming important for modern corporate environments and a significant component of the Information Security Good Practice. In this paper we also advocate that the scope of forensics needs to be expanded in order to encompass the whole information security domain and we address a number of related issues that need further attention or must be resolved in order to take full advantage of forensic readiness in a corporate environment. The expanded scope of information security due to the inclusion of forensic readiness is expected to disturb established information security good practices. As such we challenge the concept of a generic good practice, its applicability to a specific organizational context and we investigate alternatives for adapting information security good practices to accommodate digital forensics processes.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124003677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The models have been introduced by Loukas et al. [1, 2]. We have developed a collaborative decision support framework named UTH-MODELER which automates the migration of the two models into OpenMI. This framework synchronizes spatially and temporarily the two models into a collaborative simultaneous simulation. The produced software allows time series input in various formats and model extensibility. Furthermore, an optimization library for the calibration of the models has been incorporated. The experimental verification of the coupled system has been tested for the case study of the reservoir of the restored Lake Karla in Thessally Greece. The results show that the collaboration process is bounded by the time, space and optimization characteristics of the coupled models.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126400761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A typical application foresees to collect data through sensors deployed in the desired area. We proposed to use Ultrawideband (UWB) technology to provide connectivity among sensors enabling the collecting site (the sink) to store environmental parameters. When necessary those parameters are transmitted to the remote monitoring site. The main problems of sensor network is from one side to have a large number of nodes to guarantee a high connectivity level and on the other side not to have a harmful interference on licensed primary users (PUs), with which UWBs share the same bandwidth. In this paper, we propose a deployment strategy for sensors in an open outdoor area. The methodology takes into account both connectivity and coexistence issues envisaged in the deployment phase. Results show that a certain connectivity level can be reached depending on the number of sensors in the area and on propagation conditions. Moreover, an analysis on coexistence between UWBs and PUs is performed depending on the number of PUs in the same area to be preserved and the bit rate required by the application.","PeriodicalId":426248,"journal":{"name":"2010 19th IEEE International Workshops on Enabling Technologies: Infrastructures for Collaborative Enterprises","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125989585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
