Traditional security measures, such as Virtual Private Networks (VPNs), which create a secure tunnel for data transmission between the user and the corporate network, are not always adequate to protect data in cloud environments, resulting in a growing need to re-evaluate protection strategies. The COVID-19 pandemic has further intensified this demand, as organizations have been forced to adopt remote working practices on a large scale. In this scenario, trust in the final data has become a critical concern, especially given the limitations of traditional VPN solutions. In response to these challenges, Zero Trust Architecture (ZTA) and Zero Trust Network Access (ZTNA) have emerged as promising approaches. ZTNA is a technology based on the principles of ZTA that redefines network access control by eliminating implicit trust in any user or device, regardless of their location, and requiring continuous verification for every access attempt. This approach offers more granular security at the network and access control level, and is adaptable in on-premise and cloud environments, protecting data in distributed and constantly evolving corporate environments. The aim of this work is to carry out a comparative analysis of VPN and ZTNA network technologies, with an emphasis on evaluating security and performance. The security features offered by each technology will be examined, including authentication, access control and encryption, as well as the impact of these technologies on network performance in terms of latency, bandwidth and response time. Through this analysis, we aim to identify the advantages and disadvantages of each technological approach, offering valuable insights for IT professionals and organizations in selecting and implementing the solution best suited to their security and performance needs in modern corporate environments.Item Analisando a presença feminina no Ensino Superior em Tecnologia no Brasil ao longo dos anos de 2013 a 2022(2024-03-07) Ramos, Giuliane Benjamim de Oliveira; Alencar, Andrêza Leite de; Furtado, Ana Paula Carvalho Cavalcanti; http://lattes.cnpq.br/5862330768739698; http://lattes.cnpq.br/6060587704569605; http://lattes.cnpq.br/6421196285147828Masculine stigma, low family encouragement, and lack of representation are the main factors that justify the underrepresentation of women in the technology field. Therefore, this paper aims to highlight the current female landscape in Information Technology (IT) higher education courses in Brazil. To achieve this purpose, a literature review and analysis of microdata from the Higher Education Census from 2013 to 2022, provided by the National Institute for Educational Studies and Research An´ısio Teixeira (INEP), were conducted. The analysis shows significantly low female representation in higher education technology courses over the analyzed period - female enrollments do not exceed 17%, the completion rate averages 15%, and the Southeast region has the highest number of female representatives in IT courses, with São Paulo standing out. However, a trend of increase can be observed in the last two years.Item Desenvolvimento de uma plataforma de compartilhamento e análise de Dados com ênfase em LGPD(2023-04-27) Monteiro, Heitor Augusto Gomes; Medeiros, Victor Wanderley Costa de; http://lattes.cnpq.br/7159595141911505Item Avaliação experimental de replicação em banco de dados para recuperação de desastres(2020-12-18) Santos Neto, Wilson Medeiros dos; Andrade, Ermeson Carneiro de; http://lattes.cnpq.br/2466077615273972; http://lattes.cnpq.br/1208163441814364IT systems are essential for the operations of any modern business. Such systems must support operations of their corresponding company under any conditions. Disaster Recovery (DR) strategies have been implemented to help organizations mitigate unexpected failures and reduce unnecessary expenses. However, to the best of our knowledge, no other work experimentally analyzes data replication at the database layer with a focus on DR strategies. Therefore, this work evaluates a relational database replication as a mean of implementing a DR solution. We use a real testbed in a public cloud environment to perform extensive experiments aimed at implementing the replication provided by MySQL, considering various scenarios in the context of DR. Our results show how response time, Recovery Point Objective (RPO) and Recovery Time Objective (RTO) vary according to the size of the replicated data, the synchronization type (ex.: asynchronous or semisynchronous) and the configuration of the slave servers. This work can assist DR coordinators or individuals to decide which database replication configuration for disaster recovery is best for their work environment.Item Um guia para organização de hackathons corporativos no contexto de inovação(2020-10-27) Oliveira, Nycolas Lacerda de; Santos, George Augusto Valença; http://lattes.cnpq.br/8525564952779211; http://lattes.cnpq.br/9735432226857557Hackathons have become a worldwide innovation phenomenon thanks to a paradigm shift. From events focused on solving system bugs, they came to be perceived as a strategy for open innovation in small to large organizations, such as Uber and Facebook. When promoted by private companies, they are known as corporate hackathons, with key business activities as the object of analysis by the participants. Organizing a corporate hackathon is not a trivial process, considering issues such as the type of audience to be involved, the duration of the event or the technologies and challenges to be presented. Motivated by this scenario, we carry out a systematic mapping to identify the process of corporate hackathons (pre-hackathon, hackathon and post-hackathon) as well as its main characteristics (objectives, participants, duration, location and application domain) based on a set of 29 primary articles. At the end, we conducted a review by experts, with participants and hackathon organizers to interpret our findings and raise adjustment needs. In this way, our main contribution is to propose a guide for organizing corporate hackathons extracted from the literature and later enriched with the expert’s view.Item Análise dos vídeos produzidos para o ensino de Química na plataforma digital YouTube em 2021: o que os canais mais acessados abordam?(2022-05-27) Alves Neto, Francisco de Assis; Leite, Bruno Silva; http://lattes.cnpq.br/4932752031807872; http://lattes.cnpq.br/7066108122235142The accelerated evolution of technology has exceeded the use of digital resources resulting in the increase of the need for appropriation of these resources in the classroom, seeing that they are part of the social context and environment of students. In this way, teachers need to adapt to this new educational panorama that is forming. In the context of education in the virtual environment, we have studied follow-up practices of students in remote learning and done analyses of instructional progress to discover the best pedagogic effects in this medium. Academics in education argue in favour of the use of Digital Technologies of Information and Communication (DTIC) as one of the alternative resources to support the process of education and learning, because they are presenting sufficient positive results to justify their use. In the instruction of chemistry, as in other areas of knowledge pertinent to the natural sciences, alterations and improvements are increasingly requested in an attempt to find procedures and mechanisms which promote the improvement in the processes of teaching and learning of students. In this perspective, the objective of this work is to investigate the principal foci of content production to use in social media platforms, such as an instructional resource to assist students learning chemistry. Therefore we have identified the social media platforms which are the most popular for production with the focus on videos and chose to use YouTube®. In this way, the research was carried out in five steps, with the objective to improve and organize the understanding of the analyses: 1. a weighing was made with selection of 16 channels to be studied; 2. classification of the channels; 3. analysis of the content addressed in the channels; 4. analysis of types related to presentation of the content and intrinsic characteristics of the videos, using principally the Moran type of video and Mayer's principles of multimedia learning; 5. analyzing the level of engagement of the students through the commentary on the videos. The results showed that teachers who spent more time on media production in the aspects of vídeo editing and planning were well rewarded in return from their audience. Finally, this reseach concludes with the premise that the dialogue between teaching practive a–nd multimedia instructions can result in a more eficiente teaching and learning process.Item Modelo e algoritmos para seleção de sensores como serviço(2019) Verçosa, Nichene Joslin; Gonçalves, Glauco Estácio; Medeiros, Victor Wanderley Costa de; http://lattes.cnpq.br/7159595141911505; http://lattes.cnpq.br/6157118581200722; http://lattes.cnpq.br/3645909376039196The Internet of Things (IoT) plays a key role in the future of the Internet, as it will inte-grate billions of smart devices which will present sensing, actuation and data processingcapabilities. Thus, each integrated device may have one or more built-in sensors thatwill potentially generate huge amounts of data. This scenario raises the challenge ofefficiently searching and selecting the most appropriate sensors within a set that canpresent similar functionalities and capabilities. In this context, this work presents a math-ematical model for sensor selection able to maximize the attendance to user input re-quirements, such as accuracy, robustness, and availability for different types of sensors(such as temperature, pressure, humidity, wind speed, and so on) in a limited budget.This model was tested through two algorithms, the first being an optimization algorithmand the second a greedy heuristic. These solutions were evaluated and compared interms of three criteria: the optimization time, the amount of budget being utilized, andthe optimal value. The best solutions were found by the optimization algorithm but, thegreedy heuristic found close results. In some cases, the greedy heuristic found solu-tions more than 10x faster when compared to the Optimal Algorithm.Item Avanços da tecnologia da informação sobre a concorrência no setor bancário de 2014 a 2018(2019) Filgueiras, Igor Fellype Loureiro Valença; Silva Filho, Guerino Edécio da; http://lattes.cnpq.br/2977795200183918; http://lattes.cnpq.br/8480123229873786Economic theory teaches that competition generates efficiency and tends to stimulate innovation. But to what extent could the entry of new financial institutions based on information technology influence such a consolidated sector as the banking segment? This paper aims to observe the advances of information technology on competition in this sector. Data for the elaboration of the research were taken from the Brazilian Federation of Banks Research (FEBRABAN), Central Bank of Brazil and the World Bank. It is a qualitative and quantitative research, whose data included information from the main traditional and digital banks in the country. Among the main results of the survey were the relatively lower rates found in digital banking services when compared to those of traditional banks and a possible change in dynamics in physical bank branches that may be changing with the absorption of new technologies by the sector.Item O lugar da tecnologia nas licenciaturas em pedagogia das universidades públicas de Pernambuco(2019-12-04) Souza, Bruna Lima de Araújo; Tenório, Alexandro Cardoso; http://lattes.cnpq.br/6169033174942344; http://lattes.cnpq.br/4360303649622105This monograph aims to identify whether the Pedagogy Degree courses of public universities of Pernambuco contemplate the formation of technologically qualified professionals for pedagogical purposes, discussing the place of Information and Communication Technologies (ICT) in the Pedagogy Degree curricula. public universities of the State of Pernambuco. For this we seek to analyze the main documents that guide the pedagogy courses of public institutions that were available on the network as public data. And so, we turn our concern in the Political Course Projects (PPC), in the curriculum matrices and programs of the disciplines of UFPE, UFRPE and UPE. It was also sought to apply an online questionnaire to pedagogues , and pedagogy students, in order to understand which elements of the technological area the courses have addressed during the training, in order to train a pedagogical professional capable of facing the contemporary challenges of the emerging society of education. information.
