Distributed Access Control for Web and Business Processes

Middleware influenced the research community in developing a number of systems for controlling access to distributed resources. Nowadays a new paradigm for the lightweight integration of business resources from different partners is starting to take hold – Web Services and Business Processes for Web Services. Security and access control policies for Web Services protocols and distributed systems are well studied and almost standardized, but there is not yet a comprehensive proposal for an access control architecture for business processes. So, it is worth looking at the available approaches to distributed authorization as a starting point for a better understanding of what they already have and what they still need to address the security challenges for business processes

An overview to Software Architecture in Intrusion Detection System

Today by growing network systems, security is a key feature of each network infrastructure. Network Intrusion Detection Systems (IDS) provide defense model for all security threats which are harmful to any network. The IDS could detect and block attack-related network traffic. The network control is a complex model. Implementation of an IDS could make delay in the network. Several software-based network intrusion detection systems are developed. However, the model has a problem with high speed traffic. This paper reviews of many type of software architecture in intrusion detection systems and describes the design and implementation of a high-performance network intrusion detection system that combines the use of software-based network intrusion detection sensors and a network processor board. The network processor which is a hardware-based model could acts as a customized load balancing splitter. This model cooperates with a set of modified content-based network intrusion detection sensors rather than IDS in processing network traffic and controls the high-speed.Comment: 8 Pages, International Journal of Soft Computing and Software Engineering [JSCSE]. arXiv admin note: text overlap with arXiv:1101.0241 by other author

Challenging content exclusivity in network industries: the case of digital broadcasting

Interacting with network externalities and switching costs, exclusive dealings for premium contents in digital broadcasting markets allow incumbents to deny rivals critical mass and profitable market entry. A downstream company that acquires the exclusive rights to high-quality programming in the upstream market may obtain a competitive advantage over its rivals which suffer from negative externalities. Instead of fostering competition and innovation, exclusive licensing serves as an effective entry-deterrent strategy in order to preserve market power and to leverage monopolies. Although exclusivity for premium content has long been considered the only way for guaranteeing the remuneration of the vast investments in content production and platform infrastructure, this paper challenges the profitability of this exclusivity strategy in network industries. The paper questions the traditional economic assumptions underlying exclusivity of content and argues that the increasing emergence of multi-sided platforms in the broadcasting industry creates incentives for right holders to multi-home rather than single-home their contents. --Business model,digital broadcasting,exclusivity,bundling,shared access,innovation

CAUSE RELATED MARKETING – TRUE HEART-FELT CORPORATE BENEVOLENCE?

Nowadays, globally, consumers’ expectations have reached a new high, as they expect companies to act responsibly in changing the world. More than often these expectations are not met solely out of the kindness and generosity of corporations, but they are mixed in with corporate social responsibility programs and cause-related marketing. Consumers want more of the products and services they buy to support worthy social and environmental issues.Cause Related Marketing, Corporate Social Responsibility, Consumption Philanthropy, Corporate Philanthropy

Warrnambool exchange fire: consumer and social impact analysis

How can governments, communities, businesses and individuals prepare for a total communications blackout in the 21st century? Overview This report presents the findings of a research project which assessed the social impact of the Warrnambool exchange fire. The fire occurred on November 22, 2012 and caused a telecommunications outage that lasted for about 20 days. The outage affected about 100,000 people in South West Victoria, a region of Australia covering approximately 67,340 square kilometers. The social impact of the fire was researched by conducting focus groups, by gathering quantitative and qualitative data, and interviewing people affected. The research project findings call for an understanding of the need for government, communities, business and individuals to be prepared for future “extreme events” which result in telecommunications network failures.   This research was supported by a grant from the Australian Communications Consumer Action Network

Can the U.S. Get There from Here?

Climate change impacts in the United States are increasingly evident and come with steep economic and social costs. The frequency and intensity of extreme weather events has increased in recent years, bringing record-breaking heat, heavy precipitation, coastal flooding, severe droughts, and damaging wildfires.According to the National Oceanic and Atmospheric Administration (NOAA), weather-related damages in the United States were $60 billion in 2011, and are expected to be significantly greater in 2012.The mounting costs convey an unmistakable urgency to address climate change by reducing greenhouse gas emissions (GHGs). This report examines pathways for GHG reductions in the United States through actions taken at the federal and state levels without the need for new legislation from the U.S. Congress

Perception of VMS Effectiveness: A British and Canadian Perspective

Variable Message Signs are becoming a common sight on the UK Motorway network and have been well established on North American Freeways for several decades, as highway authorities strive to better manage scarce road network resources and provide travellers with up-to-date traffic information and alternative route options. The flexibility of VMS allows them to display varied information on road conditions, safety messages, alternate routes, speed limits, and general travel information. The steady growth in deployment of VMS in the next few years will lead to enhanced use of information to better manage highways and control levels of traffic congestion. The effectiveness of VMS in achieving this goal, however, depends entirely upon driver response to and perception of the information displayed. Previous research has indicated that VMS information needs to be timely, accurate, easily understandable and also believable for motorists to take any notice of it and act accordingly. This paper will report on findings from several attitudinal questionnaire surveys, conducted in and around London and Manchester in the UK, and Toronto in Canada, to determine VMS effectiveness. The studies focus on driver perception of the effectiveness of different types of information displayed and drivers’ preferences for future information provision

The Northern Arc: The Outer Perimeter Reincarnated?

Plans for the proposed Outer Perimeter were scaled back after the Regional Transportation Plan (RTP) and State Implementation Plan (SIP) lapsed in 1998 due to non-compliance with national clean air standards. In place of the 200-mile circumferential route, a dramatically modified Northern Arc emerged as an alternative in the revised alternative of the Regional Transportation Plan released in the Spring of 1999 by the Atlanta Regional Commission. In the Summer of 1999 the State Department of Transportation held a series of Public Hearings on the proposed 59 mile route extending from I-75 in the Cartersville area eastward to I-85 and GA Route 316 in the Lawrenceville area. Without advocating a position on the project, this paper examines several issues requiring resolution prior to action for or against its ultimate construction.Research Atlanta released a report in 1993 discussing issues for consideration in the public debate on the highway's fate. The current report lends some updated perspective on these issues and the text of the original report is contained in an appendix
