An Analysis of and Perspective on the Information Security Maturity Model: a case study of a Public and a Private Sector Company

Information Security (IS) is a concept that is related to protecting a set of data in order to preserve the value it has for an individual or an organization. A review of the literature shows there are four main aspects related to IS: confidentiality, integrity, availability and non-repudiation. Based on these four aspects, a new framework is put forward for analyzing the information security maturity model (ISMM) in an organization, assuming that each organization has a minimum level of information security policies in each aspect, taking into consideration the percentage of policies that this organization has from all those cited in our model. At the end, a case study was conducted in order to analyze the ISMM of a public and private sector company

Estudo das práticas no desenvolvimento de sistemas de apoio a decisão com enfoque em fatores ambientais e perfis dos usuários

A utilização de Sistemas de Apoio a Decisão (SAD) tem se tornado mais frequente no âmbito empresarial, bem como em algumas decisões pessoais. Porém, a análise, o desenvolvimento e a implantação desse tipo de sistema não é uma tarefa trivial. Os analistas responsáveis por todo ciclo de vida do desenvolvimento do SAD, encontram várias dificuldades nas análises das necessidades dos usuários e na futura satisfação no uso do sistema. Esse tipo de problemática provém, em muitos casos, da necessidade de considerar além das necessidades básicas do usuário, também considerar os fatores ambientais que impactam nas suas atividades, bem como características do seu perfil. Diante da complexidade exposta, faz-se necessário a criação de um modelo de ciclo de vida para o desenvolvimento do SAD, que considere os fatores ambientais inerentes às atividades e aos perfis dos usuários, aglutinando-os nas estruturas do SAD. Esse estudo visa à proposição de recomendações e melhores práticas para os analistas responsáveis pelo desenvolvimento do SAD, identificando as fases críticas para cada estrutura do mesmo, criando um modelo de ciclo de vida com essas fases, bem como as iterações entre ela

Collab-Net on line: An on line platform for DSS research collaboration in EWG-DSS

International audienceRecently, the scientific research collaboration has been extended to social network analysis area, which concerns in evaluating the collaborative interaction among papers authors within publication databases. The Collab-Net platform aims to investigate these publication relationship in an automatic way by a Web-based platform. The present system was developed using free platforms for software development and database system purposes. The main goal of the Collab-Net is to allow researchers to analyze their own collaborative network, as well as possibilities for future collaboration among EWG-DSS members only using a Web-based platform, in anywhere at anytime. The Collab-Net system can be used as two end-users profiles: Administrator and Member profiles

An on-line platform for supporting DSS-research collaboration (EWG-DSS Collab-Net Version 5)

International audienceOver the past few years, a growing concern has taken place among authorities over crimes committed worldwide. It has not been different in Brazil. High crime rates have encouraged government authorities involved in public safety to identify solutions to minimize crimes considered VCA (Violent Crime Against Assets). In this context, one alternative to both plan and manage security is in the division of ISA (Integrated Security Areas) neighborhoods. However, the local government needs to identify the degree of crime severity of each ISA in order to establish prevention policies and, therefore, resources management, which will make it possible for the Secretariat for Social Defense and other entities involved to establish sets of actions intending to minimize the crime rate. Furthermore, it is evident that changes are constantly happening in the crime behavior tendencies in each ISA, requiring a different set of daily actions from authorities. Therefore, the purpose of this study is to analyze the crime behavior in the region under study based on data provided by the website “onde fui roubado” and classify each ISA according to the severity of the crime through algorithms of classification of machine learning. Data analysis will take place from the KDD methodology and Big Data tools will be used to handle the large volume of data. Thus, this paper presents a framework that will allow the identification of the crimes severity in each ISA based on Big Data and Machine Learning

Modeling sequential bargains and personalities in democratic deliberation systems: A NSS for social-efficient agreements

Purpose: This paper aims to introduce a negotiation support system (NSS) with a theoretical modeling that considers the aspects of human personality and negotiator’s behavior to assist the decision-making of public managers and stakeholders in democratic bargaining processes and support social-efficient outcomes. Design/methodology/approach: A game theoretical modeling of public participatory negotiations characterized by complete and perfect information is explored with the inclusion of personality aspects and negotiation styles. The importance of the negotiation knowledge disclosure in the sequential bargains of participative budgeting is highlighted by an experiment with 162 state-owned companies’ managers and graduate students to present the contribution of the system’s applicability. Findings: A considerable number of Pareto-efficient deliberation agreements are obtained with few interactions when the negotiation strategies and the personality aspects of opponents and stakeholders are freely available (a symmetry in the public negotiation knowledge). In addition to the set of Pareto-efficient agreements, those with the best social outcome (i.e. that maximize the group satisfaction despite individual losses) are observed when the informational tool for personality and negotiation style inference is enabled. Originality/value: Many scholars argue for Pareto-efficient allocation instead of equal divisions of resources within participative democracies and public governance. This work provides a new system with an empirical application and theoretical modeling which may support those arguments based on the nonverbal negotiation aspects

Alcohol and violent behavior among football spectators: An empirical assessment of Brazilian's criminalization

The relationship between alcohol and the violent behavior, expressed as branches of hooliganism, is receiving considerable theoretical attention in social and psychological literature along the past decades while empirical researches on that matter are taken for granted. The falling in appreciate such empirical approach relies on the difficult it requires to compare of two different realities; one with alcohol intake and another without it, in order to evaluate whether it might drive sport spectators into a violent behavior, holding everything else constant. This work provides such robust statistical assessment taking into consideration a Brazilian state law 13748 of April 2009, which prohibited the sale of alcoholic beverages in Pernambuco's football stadiums. We consider the effectiveness of alcohol intervention on hooligan behavior by means of non-parametric test and a autoregressive moving average series, resorting to over ten years of data (before and during the criminalization) with regard aggression and unruly conduct committed by fans before in football matches within 3 miles from the stadium. Our results bring support to the decision of Pernambuco State Legislature to abolish in January 2016 the law in favor of the legalization of alcoholic beverages sales
