    Methodology proposal for assessing safety in WSN and IoT devices in nuclear research laboratory
    2019 - SAVOINE, MARCIA M.; ANDRADE, DELVONEI A.; MENEZES, MARIO O. de
    Nowadays 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.

    A proposal for WSN cybersecurity levels for IoT devices in nuclear research facilities
    2018 - SAVOINE, MARCIA M.; MENEZES, MARIO O.; ANDRADE, DELVONEI A. de
    Nuclear 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.

    Proposal of a methodology for the assessment of security levels of IoT wireless sensor networks in nuclear environments
    2018 - SAVOINE, MARCIA M.; MENEZES, MARIO O. de; ANDRADE, DELVONEI A. de
    The 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.
