Modelling the Spread of Botnet Malware in IoT-Based Wireless Sensor Networks

The propagation approach of a botnet largely dictates its formation, establishing a foundation of bots for future exploitation. The chosen propagation method determines the attack surface, and consequently, the degree of network penetration, as well as the overall size and the eventual attack potency. It is therefore essential to understand propagation behaviours and influential factors in order to better secure vulnerable systems. Whilst botnet propagation is generally well-studied, newer technologies like IoT have unique characteristics which are yet to be thoroughly explored. In this paper, we apply the principles of epidemic modelling to IoT networks consisting of wireless sensor nodes. We build IoT-SIS, a novel propagation model which considers the impact of IoT-specific characteristics like limited processing power, energy restrictions, and node density on the formation of a botnet. Focusing on worm-based propagation, this model is used to explore the dynamics of spread using numerical simulations and the Monte Carlo method, and to discuss the real-life implications of our findings

Central Pivot Heuristics for Botnet Attack Defense in Iot

Botnet assaults on IoT systems have become a big issue, and several strategies for botnet protection have been investigated by the academic and industry communities. While many of these methods are practical and effective for botnet attack prevention, one of the important limits is the load factor on the servers that manage monitoring and control in addition to catering to client system requests. To address load factor difficulties, the focus of this study report is on the conditions of installing a four-layer security control system based on the notion of central pivot points. Inspired by the effective and systematic Markov Chains concept, this publication proposes a four-layer filtering model that shows if botnet detection and prevention methods for servers are required. The model's simulated experimental study demonstrates the potential scope of deploying the system. The study also highlights the future possibilities of model improvisation that can reduce any erroneous signal production that is judged necessary

Cybersecurity program for Philippine higher education institutions: A multiple-case study

Digital technology has become an integral aspect of an educational system. Every state university funded the creation of Information Technology Offices to secure its Management Information System. The challenge on cybersecurity threatens the intellectual capital of students especially in a research university, theft of crucial information, and financial loss. The current study is a multiple case study of cybersecurity threats and challenges of Selected Philippine State Universities and Colleges in the National Capital Region. Sample participants were purposively selected Information Technology experts from various selected State College and Universities. A structured interview as the main instrument of the study investigated threats and challenges of cybersecurity to assess active and proactive approaches to developing a model framework for security resources in respective academic institutions. Responses gathered from the interview were consolidated and analyzed through a thematic coding process. The result of the study revealed the following challenges in cybersecurity are user education, cloud security, information security strategy, and unsecured personal devices. The creation of a program logic model will provide an informed cybersecurity planning, implementation, and assessment framework to the commission on higher education in collaboration with the Department of Information and Communication Technology, and the Philippine Association of the State Colleges and Universities

Elaboración de un plan de mitigación de riesgos de malware en IoT aplicado a un caso de estudio de una solución de gestión de salas de cirugía utilizando delphi y simulación

155 páginasLas revoluciones se han generado a lo largo de nuestra historia cuando tanto la tecnología como las nuevas formas en que las personas percibimos el mundo desencadenan cambios significativos no solo en los sistemas económicos sino también en las estructuras sociales. De los principales retos a los cuales nos enfrentamos hoy en día, uno de los más importantes es cómo entender y darle paso a las diferentes revoluciones que surgen y que significan una transformación de la humanidad. En la actualidad, estamos entrando en la cuarta revolución industrial, una revolución que cambiará esencialmente la forma en la que vivimos, trabajamos y nos conectamos o relacionamos los unos con los otros. El proceso de los seres humanos para transformar su sociedad se debe en gran medida a su curiosidad por la evolución tecnológica. La cual, durante las últimas décadas, ha permitido a la humanidad cruzar nuevas fronteras en todos los sectores económicos permitiendo realizar trabajos en periodos más cortos y con mayor precisión (Sharma et al., 2019).Maestría en Gerencia de IngenieríaMagíster en Gerencia de Ingenierí
