Estudo de vulnerabilidades em aplicações web e o seu reflexo em domínios Portugueses

Muito se tem falado sobre revolução tecnológica e do aparecimento constante de novas aplicações Web, com novas funcionalidades que visam facilitar o trabalho dos utilizadores. Mas será que estas aplicações garantem que os dados transmitidos são tratados e enviados por canais seguros (protocolos)? Que garantias é que o utilizador tem que mesmo que a aplicação utilize um canal, que prevê a privacidade e integridade de dados, esta não apresente alguma vulnerabilidade pondo em causa a informação sensível do utilizador? Software que não foi devidamente testado, aliado à falta de sensibilização por parte dos responsáveis pelo desenvolvimento de software para questões de segurança, levam ao aumento de vulnerabilidades e assim exponenciam o número de potenciais vítimas. Isto aliado ao efeito de desinibição que o sentimento de invisibilidade pode provocar, conduz ao facilitismo e consequentemente ao aumento do número de vítimas alvos de ataques informáticos. O utilizador, por vezes, não sabe muito bem do que se deve proteger, pois a confiança que depõem no software não pressupõem que os seus dados estejam em risco. Neste contexto foram recolhidos dados históricos relativos a vulnerabilidades nos protocolos SSL/TLS, para perceber o impacto que as mesmas apresentam e avaliar o grau de risco. Para além disso, foram avaliados um número significativo de domínios portugueses para perceber se os mesmos têm uma vulnerabilidade específica do protocolo SSL/TLS.

Web-assisted tobacco intervention in Portuguese : intentions to make behavioural changes and behavioural changes

ABSTRACT - The problem of how to support “intentions to make behavioural changes” (IBC) and “behaviour changes” (BC) in smoking cessation when there is a scarcity of resources is a pressing issue in public health terms. The present research focuses on the use of information and communications technologies and their role in smoking cessation. It is developed in Portugal after the ratification of WHO Framework Convention on Tobacco Control (on 8 November 2005). The prevalence of smokers over fifteen years of age within the population stood at 20.9% (30.9% for men and 11.8% for women). While the strategy of helping people to quit smoking has been emphasised at National Health Service (NHS) level, the uptake of cessation assistance has exceeded the capacity of the service. This induced the search of new theoretical and practical venues to offer alternative options to people willing to stop smoking. Among these, the National Health Plan (NHP) of Portugal (2004-2010), identifies the use of information technologies in smoking cessation. eHealth and the importance of health literacy as a means of empowering people to make behavioural changes is recurrently considered an option worth investigating. The overall objective of this research is to understand, in the Portuguese context, the use of the Internet to help people to stop smoking. Research questions consider factors that may contribute to “intentions to make behavioural changes” (IBC) and “behavioural changes” (BC) while using a Web-Assisted Tobacco Intervention Probe (WATIP). Also consideration is given to the trade-off on the use of the Web as a tool for smoking cessation: can it reach a vast number of people for a small cost (efficiency) demonstrating to work in the domain of smoking cessation (efficacy)”? In addition to the introduction, there is a second chapter in which the use of tobacco is discussed as a public health menace. The health gains achieved by stopping smoking and the means of quitting are also examined, as is the use of the Internet in smoking cessation. Then, several research issues are introduced. These include background theory and the theoretical framework for the Sense of Coherence. The research model is also discussed. A presentation of the methods, materials and of the Web-Assisted Tobacco Intervention Probe (WATIP) follows. In chapter four the results of the use of the Web-Assisted Tobacco Intervention Probe (WATIP) are presented. This study is divided into two sections. The first describes results related to quality control in relation to the Web-Assisted Tobacco Intervention Probe (WATIP) and gives an overview of its users. Of these, 3,150 answered initial eligibility questions. In the end, 1,463 met all eligibility requirements, completed intake, decided on a day to quit smoking (Dday) and declared their “intentions to make behavioural changes” (IBC) while a second targeted group of 650 did not decide on a Dday. With two quit attempts made before joining the platform, most of the participants had experienced past failures while wanting to stop. The smoking rate averaged 21 cigarettes per day. With a mean age of 35, of the participants 55% were males. Among several other considerations, gender and the Sense of Coherence (SOC) influenced the success of participants in their IBC and endeavour to set quit dates. The results of comparing males and females showed that, for current smokers, establishing a Dday was related to gender differences, not favouring males (OR=0.76, p<0.005). Belonging to higher Socio-economic strata (SES) was associated with the intention to consider IBC (when compared to lower SES condition) (OR=1.57, p<0.001) and higher number of school years (OR=0.70, p<0.005) favoured the decision to smoking cessation. Those who demonstrated higher confidence in their likelihood of success in stopping in the shortest time had a higher rate of setting a Dday (OR=0.51, p<0.001). There were differences between groups in IBC reflecting the high and low levels of the SOC score (OR=1.43, p=0.006), as those who considered setting a Dday had higher levels of SOC. After adjusting for all variables, stages of readiness to change and SOC were kept in the model. This is the first Arm of this research where the focus is a discussion of the system’s implications for the participants’ “intentions to make behavioural changes” (IBC). Moreover, a second section of this study (second Arm) offers input collected from 77 in-depth interviews with the Web-Assisted Tobacco Intervention Probe (WATIP) users. Here, “Behaviour Change” (BC) and the usability of the platform are explored a year after IBC was declared. A percentage of 32.9% of self-reported, 12-month quitters in continuous abstinence from smoking from Dday to the 12-month follow- up point of the use of the Web-Assisted Tobacco Intervention Probe (WATIP) has been assessed. Comparing the Sense of Coherence (SOC) scores of participants by their respective means, according to the two groups, there was a significant difference in these scores of non smokers (BC) (M=144,66, SD=22,52) and Sense of Coherence (SOC) of smokers (noBC) (M=131,51, SD=21,43) p=0.014. This WATIP strategy and its contents benefit from the strengthening of the smoker’s sense of coherence (SOC), so that the person’s progress towards a life without tobacco may be experienced as comprehensible, manageable and meaningful. In this sample the sense of coherence (SOC) effect is moderate although it is associated with the day to quit smoking (Dday). Some of the limitations of this research have to do with self-selection bias, sample size (power) and self-reporting (no biochemical validation). The enrolment of participants was therefore not representative of the smoking population. It is not possible to verify the Web-Assisted Tobacco Intervention Probe (WATIP) evaluation of external validity; consequently, the results obtained cannot be applied generalized. No participation bias is provided. Another limitation of this study is the associated limitations of interviews. Interviewees’ perception that fabricating answers could benefit them more than telling the simple truth in response to questions is a risk that is not evaluated (with no external validation like measuring participants’ carbon monoxide levels). What emerges in this analysis is the relevance of the process that leads to the establishment of the quit day (Dday) to stop using tobacco. In addition, technological issues, when tailoring is the focus, are key elements for scrutiny. The high number of dropouts of users of the web platform mandates future research that should concentrate on the matters of the user-centred design of portals. The focus on gains in health through patient-centred care needs more research, so that technology usability be considered within the context of best practices in smoking cessation.

Desenvolvimento de aplicações de Sistemas de Informação Geográfica WEB para gestão de resíduos urbanos.

A gestão do território contribui para o desenvolvimento socioeconómico e para o alcance de necessidades coletivas. A gestão de recursos, por sua vez, é uma das vias para atingir tais propósitos, convocando agentes, entidades e serviços para a administração de um território. O crescimento social e económico e a expansão urbana das últimas décadas tiveram um impacto significativo no consumo de recursos e na decorrente produção de resíduos, fazendo da gestão dos mesmos um importante meio para a gestão de recursos, com contributo para a gestão do território. Neste contexto, surgem serviços de gestão de resíduos urbanos, que dependem de informação geográfica referente ao seu sistema e ao do ambiente territorial em que o mesmo se insere. Face ao dinamismo e às relações entre diversos fenómenos e elementos presentes no referido ambiente, o processo de gestão de resíduos urbanos torna-se um desafio cada vez mais exigente e heterogéneo, em matéria de decisão espacial. Por esse motivo, é indispensável possuir ferramentas que integrem vários dados e que possibilitem abordagens metodológicas orientadas para uma intervenção territorial mais realista. Para tal, existem diversos métodos e técnicas, assentes em Tecnologias de Informação e Comunicação, com uma considerável adesão a soluções de Sistemas de Informação Geográfica, dada a necessidade de manipular informação com carácter espacial referente à gestão de resíduos urbanos. No quadro atual da produção e da prestação de serviços através de rede digital, as plataformas Web desses Sistemas de Informação Geográfica constituem-se como um instrumento para gestão de resíduos. Considerando o exemplo do Gabinete de Estudos, Planeamento e Controlo, dos Serviços Intermunicipalizados de Águas e Resíduos dos Municípios de Loures e Odivelas, no presente Trabalho de Projeto, pretende-se avaliar a situação atual das metodologias e dos recursos tecnológicos que um serviço deste tipo possui, percebendo o contributo que aplicações de Sistemas de Informação Geográfica Web podem ter para a concretização da sua missão, na conjuntura atual da tecnologia, da informação e da comunicação na Administração Pública. Assim, o presente Trabalho de Projeto propõe também um modelo de desenvolvimento das referidas aplicações, assentes em Sistemas de Informação Geográfica Desktop e Web de código aberto, livres e gratuitos. As aplicações abarcam informação interna, referente ao sistema de resíduos urbanos, dos Serviços Intermunicipalizados de Águas e Resíduos dos Municípios de Loures e Odivelas, e informação externa diversa, referente ao seu território de intervenção. A integração e relação da informação interna e externa, com resultados nas aplicações, são apresentadas como possíveis meios de assistência aos procedimentos efetuados no Gabinete de Estudos, Planeamento e Controlo e à prestação efetiva do serviço de gestão de resíduos urbanos. Igualmente, é possível inferir a versatilidade, a aplicabilidade e o potencial de aplicações de Sistemas de Informação Geográfica, em diversas vertentes e escalas de gestão do território.

Development of a data acquisition system to characterise sustainable energy technologies and to support Web-Based learning (DAQ-WBL)

Driven by concerns about rising energy costs, security of supply and climate change a new wave of Sustainable Energy Technologies (SET’s) have been embraced by the Irish consumer. Such systems as solar collectors, heat pumps and biomass boilers have become common due to government backed financial incentives and revisions of the building regulations. However, there is a deficit of knowledge and understanding of how these technologies operate and perform under Ireland’s maritime climate. This AQ-WBL project was designed to address both these needs by developing a Data Acquisition (DAQ) system to monitor the performance of such technologies and a web-based learning environment to disseminate performance characteristics and supplementary information about these systems. A DAQ system consisting of 108 sensors was developed as part of Galway-Mayo Institute of Technology’s (GMIT’s) Centre for the Integration of Sustainable EnergyTechnologies (CiSET) in an effort to benchmark the performance of solar thermal collectors and Ground Source Heat Pumps (GSHP’s) under Irish maritime climate, research new methods of integrating these systems within the built environment and raise awareness of SET’s. It has operated reliably for over 2 years and has acquired over 25 million data points. Raising awareness of these SET’s is carried out through the dissemination of the performance data through an online learning environment. A learning environment was created to provide different user groups with a basic understanding of a SET’s with the support of performance data, through a novel 5 step learning process and two examples were developed for the solar thermal collectors and the weather station which can be viewed at http://www.kdp 1 .aquaculture.ie/index.aspx. This online learning environment has been demonstrated to and well received by different groups of GMIT’s undergraduate students and plans have been made to develop it further to support education, awareness, research and regional development.
