    Towards Secure 5G Service Marketplaces: A review of “an SLA-driven Trust and Reputation Management Framework” [Póster]
    (Universidad de Sevilla. Escuela Técnica Superior de Ingeniería Informática, 2024) Jorquera Valero, José María; Gil Pérez, Manuel; Martínez Pérez, Gregorio
    In the 5G era, marked by an expansive network of stakeholders, resources, and services, establishing trust in distributed marketplaces is crucial to ensure fruitful business agreements. A proposed reputation-based trust management framework aims to secure reliable transactions by analyzing behavior and predicting trust scores, further reinforced by an SLA-driven reward and punishment system for real-time trust adaptation. Demonstrated through real-life experiments in the 5GZORRO H2020 European project, this framework effectively identifies bad-mouthing attacks with 67% accuracy, even with significant recommender compromise, showcasing its resilience to misbehavior.

    Unleashing Security: Shaping the Resilient Future of 5G/B5G Network Orchestration
    (Universidad de Sevilla. Escuela Técnica Superior de Ingeniería Informática, 2024) Landa Arrue, Aitor; Urbieta, Aitor; Garitano, Iñaki
    In the era of Industry 4.0, expanding device connectivity via 5G and Beyond 5G (B5G) networks introduces significant security challenges, and advanced solutions for attack detection and mitigation are needed. This study focuses on the complexities of distributed architecture inherent to 5G/B5G networks, underscoring the crucial role of network service orchestration, Moving Target Defense strategies, and advanced attack detection mechanisms. This research identifies cuttingedge mechanisms for ensuring the security of service orchestration through an in-depth state-of-the-art analysis, focusing on artificial intelligence-driven solutions for zero-touch networks. By minimizing human intervention, these networks offer enhanced security and efficiency
