Item Utilização de inteligência de ameaças cibernéticas para prevenção e mitigação de ataques ransomware: uma revisão sistemática da literatura(2025-02-27) Cabral, Rennan Luis Barros; Lins, Fernando Antonio Aires; http://lattes.cnpq.br/2475965771605110; http://lattes.cnpq.br/4612932794474682Item Redes ópticas de acesso: uma análise comparativa entre EPON e SuperPON(2024-12-12) Silva, Marcos Antonio da; Araújo, Danilo Ricardo Barbosa de; http://lattes.cnpq.br/2708354422178489The demand for high transmission rates for Internet services has been increasing over time, resulting in a large flow of data. This project focuses on access networks, which provide quality intemet services to homes and small business. Optical fiber offers high transmission rates, both for upstream and downstream, capable of transporting several Gbps, depending on the network architecture and equipment used, such as the OLT (Optical Line Terminal). Passive optical networks are access networks that use interconnected optical fibers in a star topology and point-to-multipoint configuration, consisting only of passive optical components between the Optical Line Terminal (OLT) and the Optical Network Unit (ONU). As a technological evolution strategy, they can be used to leverage the installed base of copper cables and coaxial cables in the access network, serving as feeder cables for technologies such as Digital Subscriber Line (DSL), cable modem, and Local Multipoint Distribution System (LMDS), and, in the future, to provide optical fiber to user premises. This project aims to show the difference between EPON and SuperPON technologies, both of which are passive network technologies, and to verify the cost-effectiveness of both. In this work, we explore the particularities of both technologies, considering the size of the network. We observe that EPON (Ethernet Passive Optical Network) stands out for its significantly lower cost compared to SuperPON when expanding the network to smaller areas. This is due to the lower need for expenses with CO (Central Office) and equipment. On the other hand, SuperPON presents a cost advantage when expanding to larger areas, as it requires less CO. Therefore, it becomes a more advantageous option compared to EPON in such network expansion scenarios. Another comparison we will address is the number of ONUs (Optical Network Unit) that we can obtain compared to EPON and SuperPON. In EPON, one fiber can support up to 64 ONUs in a network with a 1:8 splitter, resulting in 8 CTOs (Optical Termination Boxes). In a network with a 1:16 splitter, we can have 4 CTOs. On the other hand, in the SuperPON network, we can accommodate up to 1024 ONUS on a single fiber with a 1:8 splitter, resulting in 128 CTOs. With a 1:16 splitter, we can have 64 CTOs.Item Rede de Atenção Psicossocial na cidade de Olinda: desenvolvimento de um protótipo web para melhoria do acesso aos serviços de saúde mental(2024-10-04) Silva, Isaque João da; Andrade, Ermeson Carneiro de; Araújo, Carlos Julian Menezes; http://lattes.cnpq.br/3156174527107999; http://lattes.cnpq.br/2466077615273972; http://lattes.cnpq.br/1877126987902999This article highlights the importance of the Psychosocial Care Network (RAPS) in the mental health of the population and the need to provide clear and accessible information about its services in the city of Olinda.

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 Uso de Blockchain na rastreabilidade de produtos: uma revisão sistemática da literatura(2024-10-03) Alves, Edvaldo Ribeiro; Lins, Fernando Antonio Aires; http://lattes.cnpq.br/2475965771605110; http://lattes.cnpq.br/1693577382765854In recent times, Blockchain has ceased to be exclusively associated with the digital currency Bitcoin and has expanded its applications to a variety of sectors such as healthcare, product traceability, the Internet of Things, and education. Traceability is becoming increasingly crucial in various sectors due to a combination of factors involving security, transparency, sustainability, and operational efficiency. Traceability has become an essential strategic tool to ensure safety, enhance transparency and efficiency, and meet regulatory and ethical demands. However, a gap has been observed in the current literature concerning the review and analysis of research initiatives focused on product traceability using Blockchain, particularly detailing how Blockchain operates in this context and the improvements the technology brings to this environment. Although there are studies exploring the application of Blockchain technology in different areas, the current literature lacks a comprehensive synthesis specifically addressing product traceability. This gap is particularly relevant given the growing interest and importance of traceability in the supply chain to ensure transparency, authenticity, and product safety. Therefore, this work aims to fill this gap by providing an analysis of existing research initiatives in this area. The present work seeks to comprehensively explore the implications of this combination, analyzing how Blockchain can transform the way products are tracked and managed. In this context, the main contribution of this paper is a systematic review of existing research on Blockchain-based systems developed to enhance traceability. This involves understanding how Blockchain is applied to track and verify the improvements it brings to those who adopt this combination. This systematic mapping also offers an overview of current research trends in this area. Additionally, it sheds light on research and innovation challenges that remain open in this area.Item Racismo algorítmico no desenvolvimento de software: um estudo de caso sobre letramento racial no ensino superior(2024-08-05) Silva, Jamelly Nascimento; Falcão, Taciana Pontual da Rocha; Santos, George Augusto Valença; http://lattes.cnpq.br/8525564952779211; http://lattes.cnpq.br/5706959249737319This article presents a case study on the topic of algorithmic racism in software development, focusing on racial literacy in higher education.
