Artigo IPEN-doc 28395 Monitoring network for nuclear research laboratory using WSN and IoT devices2020 - ROCHA, KAIO; COSTA, MATHEUS; SAVOINE, MARCIAThis work presents a proposal of implementation of an automatic monitoring system for environments who does experimentation and manipulation of ionizing radioactive particles, having as a base scenario the structures off nuclear energy research laboratories through sensors coupled to integrated microprocessor circuit boards, to carry out the communication between the sensors a Wireless Sensor Network with star topology was raised by resorting in the Internet of Things paradigm. For the network security, the concept of layered access level was applied, specifically, access level according to the criticality off the process and environment whose the sensors are exposed to.Artigo IPEN-doc 26332 Methodology proposal for assessing safety in WSN and IoT devices in nuclear research laboratory2019 - SAVOINE, MARCIA M.; ANDRADE, DELVONEI A.; MENEZES, MARIO O. deNowadays there is a gap due to the absence of an updated and formalized methodology that can be used to assess security levels in WSNs (Wireless Sensor Network) under IoT (Internet of Things) devices in nuclear environments (which are considered hostile environments and require a higher level of security). This gap causes information security professionals to have di culties in making a broad assessment of the vulnerabilities in their WSNs, with greater concern when coupled with IoT devices. This work aims to present a methodology to evaluate the reliability of the use of levels security with IoT devices for nuclear installations using WSNs. The proposal of the methodology consists of 5 main stages and 21 substages, which are part of the category of a function in groups of cyber security results that are linked to programmatic needs and speci c activities of mandatory execution. Understanding so that the security of a WSN considering the current IoT context for nuclear installations is necessary, where important characteristics in these critical environments should be explored (e g., the presence of radioactivity, in addition to the decontamination of materials and equipment, determine access to authorized persons). The application of the defense-in-depth concept of anomaly solution management and prevention against atypical events to provide an e ective safety mechanism, ensuring its safe use in these high criticality environments.Resumo IPEN-doc 25188 Uso de WSN em dispositivos IoT em Reserva Indígena no Tocantins2018 - MORAIS, HENRIQUE M.; ROCHA, KAIO R.; TEIXEIRA, LETICIA dos S.; COSTA, MATHEUS F.; SAVOINE, MARCIA M.; MENEZES, MARIO O. deArtigo IPEN-doc 24789 Proposal of a methodology for the assessment of security levels of IoT wireless sensor networks in nuclear environments2018 - SAVOINE, MARCIA M.; MENEZES, MARIO O. de; ANDRADE, DELVONEI A. deThe use of Wireless Sensor Networks (WSN) associated with the reality of an Internet of Things (IoT) scenario in nuclear environments is a growing security concern. In this context, standards are intensified to preserve the physical integrity of these facilities considered to be highly critical due to the size of the impacts of safety accidents. This paper presents a proposal to build a methodology to evaluate the security levels of WSNs with IoT devices when used in nuclear areas. The proposal is initially based on related work to establish a more concrete initial framework and is structured in consistent steps from previous scientific studies.
