    Awareness of cybersecurity topics facilitates software developers to produce secure code. This awareness is especially important in industrial environments for the products and services in critical infrastructures. In this work, we address how to raise awareness of software developers on the topic of secure coding. We propose the “CyberSecurity Challenges”, a serious game designed to be used in an industrial environment and address software developers’ needs. Our work distills the experience gained in conducting these CyberSecurity Challenges in an industrial setting. The main contributions are the design of the CyberSecurity Challenges events, the analysis of the perceived benefits, and practical advice for practitioners who wish to design or refine these games.info:eu-repo/semantics/acceptedVersio

    Is secure coding education in the industry needed? An investigation through a large scale survey

    Get PDF
    The Department of Homeland Security in the United States estimates that 90% of software vulnerabilities can be traced back to defects in design and software coding. The financial impact of these vulnerabilities has been shown to exceed 380 million USD in industrial control systems alone. Since software developers write software, they also introduce these vulnerabilities into the source code. However, secure coding guidelines exist to prevent software developers from writing vulnerable code. This study focuses on the human factor, the software developer, and secure coding, in particular secure coding guidelines. We want to understand the software developers' awareness and compliance to secure coding guidelines and why, if at all, they aren't compliant or aware. We base our results on a large-scale survey on secure coding guidelines, with more than 190 industrial software developers. Our work's main contribution motivates the need to educate industrial software developers on secure coding guidelines, and it gives a list of fifteen actionable items to be used by practitioners in the industry. We also make our raw data openly available for further research.info:eu-repo/semantics/acceptedVersio

    Secure software development is a crucial topic that companies need to address to develop high-quality software. However, it has been shown that software developers lack secure coding awareness. In this work, we use a serious game approach that presents players with Java challenges to raise Java programmers' secure coding awareness. Towards this, we adapted an existing platform, embedded in a serious game, to assess Java secure coding exercises and performed an empirical study. Our preliminary results provide a positive indication of our solution's viability as a means of secure software development training. Our contribution can be used by practitioners and researchers alike through an overview on the implementation of automatic security assessment of Java CyberSecurity Challenges and their evaluation in an industrial context.info:eu-repo/semantics/publishedVersio

    No Brasil, foi marcante a ocupação de grupos humanos em áreas com potencial hídrico elevado para o desenvolvimento da agricultura irrigada. Neste contexto, inseri-se o rio São Francisco, que vem passando por constantes mudanças em relação à sua cobertura vegetal original. O presente estudo buscou responder as seguintes perguntas: Como fazendeiros e funcionários representam as possíveis mudanças da vegetação ciliar ao longo do tempo? Quais os eventos históricos responsáveis por essas possíveis mudanças? Como os fazendeiros e funcionários representam os aspectos relacionados às utilidades e à conservação da vegetação ciliar? Um total de 17 homens e oito mulheres, proprietários e funcionários de áreas próximas à vegetação ripária em cinco municípios dos estados da Bahia e Pernambuco, participaram da pesquisa. Entrevistas semiestruturadas e entrevista semiestruturada do tipo projetiva foram empregadas para investigar as representações sobre conservação da mata ciliar e mudanças locais da paisagem, bem como resgatar os eventos históricos que as influenciaram. Com o objetivo de registrar o conhecimento local sobre a diversidade de espécies úteis mais importantes foi utilizada a técnica de lista livre. Em relação às modificações da paisagem verificou-se que apenas um entrevistado afirmou não haver mudanças na vegetação ciliar, seis afirmaram que houve mudanças para pior e quatro para melhor. Quatro proprietários responderam que as mudanças na vegetação iniciaram há 10 anos, seis há mais de 30 anos, dois não sabiam e um não verificou mudanças. Entre os funcionários, cinco afirmaram que elas ocorreram há mais de 20 anos, quatro há mais de 10 anos e para quatro deles a vegetação não mudou. Observou-se que todos os informantes concordaram que a vegetação deve ser conservada, sendo que 64% destacaram que ela protege o rio e os outros 36% indicaram outras utilidades para a vegetação ciliar, tais como: atrair chuva, fazer sombra, usos medicinais e aumentar a quantidade de oxigênio. Sobre quem seriam os responsáveis pela conservação: 48% disseram que eram os próprios proprietários de terras, 48% afirmaram que era dever de todos conservar e 4% atribuíram a responsabilidade ao IBAMA. Eles também apontaram soluções para a conservação da vegetação ripária, como o reflorestamento (39%), não desmatar (17%), educação ambiental (13%) e cuidar bem (13%). Futuros projetos de restauração que podem vir a ocorrer nessa área devem levar em consideração essas diferentes representações, demandas e expectativas

    Local representations of change and conservation of the riparian forests along the São Francisco River (Northeast Brazil).

    Investigations of local representations about the environment allow for the elucidation of historical landscape transformation and the elaboration of strategies for environmental conservation. Thus, this study aimed to answer the following questions. How does the local population represent the possible changes in riparian vegetation over time? What historical events were responsible for these possible changes? How does the local population represent concerns related to the use andmaintenance of riparian vegetation? This study was carried out with 87 informants from three communities: two rural ex-settlement communities and one quilombo in Northeastern Brazil. According to the informants, therewere changes in the riparian vegetation. Themain causes of these changes include the type of agriculture practiced in the region and the building of a large dam to provide water to the city of Sobradinho in the state of Bahia. However, there was no significant difference between the number of informants who said that the changes were for the worse and those who said that they were for the better. In addition, the respondents reported an increase in the abundance of exotic species and a decrease in the abundance of native species. Thus, the importance of including this group of people in the process of the forest restoration that will occur in the region is emphasized because they possess information about the past vegetation changes and their causes. They can also indicatewhich species should be prioritized for replanting according to their usage needs and they understand the importance of conserving riparian vegetation

    The ALPS project release 1.3: open source software for strongly correlated systems

    Full text link
    We present release 1.3 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open source software project to develop libraries and application programs for the simulation of strongly correlated quantum lattice models such as quantum magnets, lattice bosons, and strongly correlated fermion systems. Development is centered on common XML and binary data formats, on libraries to simplify and speed up code development, and on full-featured simulation programs. The programs enable non-experts to start carrying out numerical simulations by providing basic implementations of the important algorithms for quantum lattice models: classical and quantum Monte Carlo (QMC) using non-local updates, extended ensemble simulations, exact and full diagonalization (ED), as well as the density matrix renormalization group (DMRG). Changes in the new release include a DMRG program for interacting models, support for translation symmetries in the diagonalization programs, the ability to define custom measurement operators, and support for inhomogeneous systems, such as lattice models with traps. The software is available from our web server at http://alps.comp-phys.org/

    É previsto um grande aumento da população humana nas regiões em desenvolvimento do globo nos próximos anos. Tais regiões serão inevitavelmente demandadas por aumento na produção de alimentos. Espécies ainda não domesticadas ou semi-domesticadas possuem enorme potencial para alimentar o número crescente de pessoas do planeta. Ciente de tais desafios, a Embrapa inclui desde 2009 em sua Plataforma Nacional de conservação de Recursos Genéticos, os animais silvestres de interesse econômico. Coleções de animais, bancos de DNA e bancos de germoplasma são mantidos por unidades da empresa e por parceiros da rede, com vistas ao desenvolvimento do setor agropecuário em bases sustentáveis. A plataforma e suas redes de conservação de recursos genéticos propiciam pesquisas sobre as espécies conservadas, gerando uma notável quantidade de informações sobre o genótipo, o fenótipo e o potencial aproveitamento de tais animais em sistemas sustentáveis de produção, para benefício da população humana. Por seu caráter contínuo, a necessidade de captar recursos para manutenção das ações da plataforma é constante

    Measurement of the production of charm jets tagged with D0^{0} mesons in pp collisions at s\sqrt{s}= 7 TeV

    The production of charm jets in proton-proton collisions at a center-of-mass energy of s=7\sqrt{s}=7 TeV was measured with the ALICE detector at the CERN Large Hadron Collider. The measurement is based on a data sample corresponding to a total integrated luminosity of 6.236.23 nb1{\rm nb}^{-1}, collected using a minimum-bias trigger. Charm jets are identified by the presence of a D0^0 meson among their constituents. The D0^0 mesons are reconstructed from their hadronic decay D0^0\rightarrowKπ+^{-}\pi^{+}. The D0^0-meson tagged jets are reconstructed using tracks of charged particles (track-based jets) with the anti-kTk_{\mathrm{T}} algorithm in the jet transverse momentum range 5<pT,jetch<305<p_{\rm{T,jet}}^{\mathrm{ch}}<30 GeV/c{\rm GeV/}c and pseudorapidity ηjet<0.5|\eta_{\rm jet}|<0.5. The fraction of charged jets containing a D0^0-meson increases with pT,jetchp_{\rm{T,jet}}^{\rm{ch}} from 0.042±0.004(stat)±0.006(syst)0.042 \pm 0.004\, \mathrm{(stat)} \pm 0.006\, \mathrm{(syst)} to 0.080±0.009(stat)±0.008(syst)0.080 \pm 0.009\, \rm{(stat)} \pm 0.008\, \rm{(syst)}. The distribution of D0^0-meson tagged jets as a function of the jet momentum fraction carried by the D0^0 meson in the direction of the jet axis (zchz_{||}^{\mathrm{ch}}) is reported for two ranges of jet transverse momenta, 5<pT,jetch<155<p_{\rm{T,jet}}^{\rm{ch}}<15 GeV/c{\rm GeV/}c and 15<pT,jetch<3015<p_{\rm{T,jet}}^{\rm{ch}}<30 GeV/c{\rm GeV/}c in the intervals 0.2<zch<1.00.2<z_{||}^{\rm{ch}}<1.0 and 0.4<zch<1.00.4<z_{||}^{\rm{ch}}<1.0, respectively. The data are compared with results from Monte Carlo event generators (PYTHIA 6, PYTHIA 8 and Herwig 7) and with a Next-to-Leading-Order perturbative Quantum Chromodynamics calculation, obtained with the POWHEG method and interfaced with PYTHIA 6 for the generation of the parton shower, fragmentation, hadronisation and underlying event.Comment: 29 pages, 8 captioned figures, 3 tables, authors from page 24, published version, figures at http://alice-publications.web.cern.ch/node/525
