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.Artigo IPEN-doc 25911 Caracterização de testbed em WSN e IoT na reserva indígena no norte do Tocantins2018 - MORAIS, HENRIQUE M.; ROCHA, KAIO R.; TEIXEIRA, LETICIA dos S.; COSTA, MATHEUS F.; SAVOINE, MARCIA M.; MENEZES, MARIO O. deThe use of a WSN with IoT devices in a critical scenario makes it relevant to perform tests to presume the behavior of the elements of a network in order to optimize its application. This work will present an experiment performed in the FIT IoT-Lab testbed platform, characterizing the Xambioá indigenous reservation, located in the northern region in the state of Tocantins, as an application scenario.Artigo IPEN-doc 25543 A proposal for WSN cybersecurity levels for IoT devices in nuclear research facilities2018 - SAVOINE, MARCIA M.; MENEZES, MARIO O.; ANDRADE, DELVONEI A. deNuclear facilities represent a growing security concern and the standards aimed at preserving the physical integrity of these highly critical environments have intensified, considering the scale of the impacts of nuclear accidents. This paper presents a proposal to establish layers, levels and zones of cybersecurity for Wireless Sensor Networks (WSNs) with IoT devices in these critical and hostile environments, taking into consideration the concept of defense-in-depth. The proposal of establishing cybersecurity through layers and levels provides the ability to control access to IoT devices in nuclear facilities, in order to maintain a high level of privacy.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.Resumo IPEN-doc 24599 Proposed methodology for evaluating safety levels in WSN on IOT devices in nuclear environments2017 - SAVOINE, M.M.; ANDRADE, D.A.; MENEZES, M.O.; ROCHA, K.R.; MORAIS, H.M.; TEIXEIRA, L.S.; COSTA, M.F.Over the last few years, concern for safety in nuclear facilities has grown considerably, and as a result, standards have been stepped up to preserve the physical integrity of these facilities. Similarly, the Internet of Things (IoT), together with Wireless Sensor Networks or Wireless Sensor Networks (WSN), are gaining importance in the continuous advancement of information and communication technologies, especially due to their connection and Internet integration across multiple application areas. Nuclear areas can be considered as critical and hostile environments because of the inherent risk of the presence of radioactivity and the extent of the impact of safetyrelated problems. Therefore, a WSN is an innovative technology with potential to perform distributed sensing tasks, especially for security monitoring and evaluation applications. Such environments, which are highly critical, require the existence of an appropriate methodology for the evaluation of issues related to the employment security of these WSNs and IoT technologies. Specifically in the nuclear environment, no indications of appropriate methodologies for such an assessment are found today in the literature, even taking into account the nuclear safety scenario and IAEA (International Atomic Energy Agency) recommendations and documentation. Given the high degree of safety importance in these hostile environments, specifically nuclear, due to the scale of the impacts caused by accidents in these places, it is essential to develop a methodology to preserve the physical integrity of these installations from the point of view of the operation of the WSNs and IoT. This work presents, at an early stage of development, an innovative methodology for the evaluation of the security levels in a WSN with IoT devices in nuclear environments, being composed by the hybridization of phases, aggregated to characteristic factors of a context of a WSN coupled to devices IoT.
