    Cloud computing has emerged as a popular paradigm and an attractive model for providing a reliable distributed computing model.it is increasing attracting huge attention both in academic research and industrial initiatives. Cloud deployments are paramount for institution and organizations of all scales. The availability of a flexible, free open source cloud platform designed with no propriety software and the ability of its integration with legacy systems and third-party applications are fundamental. Open stack is a free and opensource software released under the terms of Apache license with a fragmented and distributed architecture making it highly flexible. This project was initiated and aimed at designing a secured cloud infrastructure called BradStack, which is built on OpenStack in the Computing Laboratory at the University of Bradford. In this report, we present and discuss the steps required in deploying a secured BradStack Multi-node cloud infrastructure and conducting Penetration testing on OpenStack Services to validate the effectiveness of the security controls on the BradStack platform. This report serves as a practical guideline, focusing on security and practical infrastructure related issues. It also serves as a reference for institutions looking at the possibilities of implementing a secured cloud solution.Comment: 38 pages, 19 figures

    Public transit systems around the world have for decades served as a principal venue for terrorist acts. Today, transit security is widely viewed as an important public policy issue and is a high priority at most large transit systems and at smaller systems operating in large metropolitan areas. Research on transit security in the United States has mushroomed since 9/11; this study is part of that new wave of research. This study contributes to our understanding of transit security by (1) reviewing and synthesizing nearly all previously published research on transit terrorism; (2) conducting detailed case studies of transit systems in London, Madrid, New York, Paris, Tokyo, and Washington, D.C.; (3) interviewing federal officials here in the United States responsible for overseeing transit security and transit industry representatives both here and abroad to learn about efforts to coordinate and finance transit security planning; and (4) surveying 113 of the largest transit operators in the United States. Our major findings include: (1) the threat of transit terrorism is probably not universal—most major attacks in the developed world have been on the largest systems in the largest cities; (2) this asymmetry of risk does not square with fiscal politics that seek to spread security funding among many jurisdictions; (3) transit managers are struggling to balance the costs and (uncertain) benefits of increased security against the costs and (certain) benefits of attracting passengers; (4) coordination and cooperation between security and transit agencies is improving, but far from complete; (5) enlisting passengers in surveillance has benefits, but fearful passengers may stop using public transit; (6) the role of crime prevention through environmental design in security planning is waxing; and (7) given the uncertain effectiveness of antitransit terrorism efforts, the most tangible benefits of increased attention to and spending on transit security may be a reduction in transit-related person and property crimes

    Mental Health in the Workplace: Situation Analyses, Finland

    [From Introduction] Mental health problems are among the most important contributors to the global burden of disease and disability. Of the ten leading causes of disability worldwide, five are psychiatric conditions: unipolar depression, alcohol use, bipolar affective disorder (manic depression), schizophrenia and obsessive-compulsive disorder. The burden of mental disorders on health and productivity throughout the world has long been profoundly underestimated.2 The impact of mental health problems in the workplace has serious consequences not only for the individuals whose lives are influenced either directly or indirectly, but also for enterprise productivity. Mental health problems strongly influence employee performance, rates of illnesses, absenteeism, accidents, and staff turnover. The workplace is an appropriate environment in which to educate and raise individuals\u27 awareness about mental health problems. For example, encouragement to promote good mental health practices, provide tools for recognition and early identification of the symptoms of problems, and establish links with local mental health services for referral and treatment can be offered. The need to demystify the topic and lift the taboos about the presence of mental health problems in the workplace while educating the working population regarding early recognition and treatment will benefit employers in terms of higher productivity and reduction in direct and in-direct costs. However, it must be recognised that some mental health problems need specific clinical care and monitoring, as well as special considerations for the integration or reintegration of the individual into the workforce
