CyberSecurity challenges for software developer awareness training in industrial environments

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

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

Automated Java challenges' security assessment for training in industry: Preliminary results

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

Representações dos proprietários e funcionários de fazendas sobre as mudanças e conservação da vegetação ciliar às margens do rio São Francisco, Nordeste do Brasil.

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

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/

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 $\sqrt{s}=7$ 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 $6.23$ ${\rm nb}^{-1}$, collected using a minimum-bias trigger. Charm jets are identified by the presence of a D$^0$ meson among their constituents. The D$^0$ mesons are reconstructed from their hadronic decay D$^0\rightarrow$K$^{-}\pi^{+}$. The D$^0$-meson tagged jets are reconstructed using tracks of charged particles (track-based jets) with the anti-$k_{\mathrm{T}}$ algorithm in the jet transverse momentum range $5<p_{\rm{T,jet}}^{\mathrm{ch}}<30$ ${\rm GeV/}c$ and pseudorapidity $|\eta_{\rm jet}|<0.5$. The fraction of charged jets containing a D$^0$-meson increases with $p_{\rm{T,jet}}^{\rm{ch}}$ from $0.042 \pm 0.004\, \mathrm{(stat)} \pm 0.006\, \mathrm{(syst)}$ to $0.080 \pm 0.009\, \rm{(stat)} \pm 0.008\, \rm{(syst)}$. The distribution of D$^0$-meson tagged jets as a function of the jet momentum fraction carried by the D$^0$ meson in the direction of the jet axis ($z_{||}^{\mathrm{ch}}$) is reported for two ranges of jet transverse momenta, $5<p_{\rm{T,jet}}^{\rm{ch}}<15$ ${\rm GeV/}c$ and $15<p_{\rm{T,jet}}^{\rm{ch}}<30$ ${\rm GeV/}c$ in the intervals $0.2<z_{||}^{\rm{ch}}<1.0$ and $0.4<z_{||}^{\rm{ch}}<1.0$, 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

Comparative analysis of four medicinal floras: phylogenetic methods to identify cross-cultural patterns

Summary Four medicinal floras were compared using phylogenetic methods, to test whether there are shared patterns in medical plant use at the level of the whole medicinal floras, or for specific therapeutic applications. Checklists of the native plants and medicinal plants of Oman were compiled, and analyzed alongside existing checklists for Nepal, the Cape of South Africa and New Zealand. We reconstructed a plant phylogeny at generic level for Oman, and a new, more inclusive phylogeny to represent the genera found in all four local floras. Methods from community phylogenetics were used to identify clustering and overdispersion of the plants used. The impacts of using local or more inclusive phylogenies and different null model selections were explored. We found that Omani medicinal plant use emphasizes the same deep lineages of flowering plants as the other three medicinal floras, most strongly when comparing Omani and Nepalese medicinal plants. Drivers of this similarity might be floristic composition, opportunity for exchange of knowledge and shared beliefs in the causation of illness. Phylogenetic patterns among therapeutic applications are cross‐predictive within and between cultures, and must be interpreted with care since inappropriate use of null models can result in spurious similarity. High levels of cross‐predictivity suggest that targeting plants used for specific therapeutic applications to identify specific bioactives may have limited value. We outline the questions that might be addressed using a global phylogeny and medicinal plant checklists, suggest the best methods for future studies and propose how findings might be interpreted
