The proliferation of Internet of Things (IoT) devices has introduced significant challenges in cybersecurity, particularly in the realm of intrusion detection. While effective, traditional centralized machine learning approaches often compromise data privacy and scalability due to the need for data aggregation. In this study, we propose a federated learning framework for near-real-time intrusion detection in IoT environments. Federated learning enables decentralized model training across multiple devices without exchanging raw data, thereby preserving privacy and reducing communication overhead. Our approach builds upon a previously proposed hybrid model, which combines a machine learning model deployed on IoT devices with a second-level cloud-based analysis. This previous work required all data to be passed to the cloud in aggregate form, limiting security. We extend this model to incorporate federated learning, allowing for distributed training while maintaining high accuracy and privacy. We evaluate the performance of our federated-learning-based model against a traditional centralized model, focusing on accuracy retention, training efficiency, and privacy preservation. Our experiments utilize actual attack data partitioned across multiple nodes. The results demonstrate that this hybrid federated learning not only offers significant advantages in terms of data privacy and scalability but also retains the previous competitive accuracy. This paper also explores the integration of federated learning with cloud-based infrastructure, leveraging platforms such as Databricks and Google Cloud Storage. We discuss the challenges and benefits of implementing federated learning in a distributed environment, including the use of Apache Spark and MLlib for scalable model training. The results show that all the algorithms used maintain an excellent identification accuracy (98% for logistic R=regression, 97% for SVM, and 100% for Random Forest). We also report a very short training time (less than 11 s on a single machine). The previous very low application time is also confirmed (0.16 s for over 1,697,851 packets). Our findings highlight the potential of federated learning as a viable solution for enhancing cybersecurity in IoT ecosystems, paving the way for further research in privacy-preserving machine learning techniques.

Technology-facilitated abuse, so-called “tech abuse,” through phones, trackers, and other emerging innovations, has a substantial impact on the nature of intimate partner violence (IPV). The current chapter examines the risks and harms posed to IPV victims/survivors from the burgeoning Internet of Things (IoT) environment. IoT systems are understood as “smart” devices such as conventional household appliances that are connected to the internet. Interdependencies between different products together with the devices' enhanced functionalities offer opportunities for coercion and control. Across the chapter, we use the example of IoT to showcase how and why tech abuse is a socio-technological issue and requires not only human-centered (i.e., societal) but also cybersecurity (i.e., technical) responses. We apply the method of “threat modeling,” which is a process used to investigate potential cybersecurity attacks, to shift the conventional technical focus from the risks to systems toward risks to people. Through the analysis of a smart lock, we highlight insufficiently designed IoT privacy and security features and uncover how seemingly neutral design decisions can constrain, shape, and facilitate coercive and controlling behaviors.

Internet of Things (IoT) is expected to improve our lifestyle in a noticeable way. However, although the IoT holds a lot of chances, it contains a lot of serious risks. This leads to a focus on developing security techniques that can increase the security level of IoT. Blockchain is considered as an innovative technique for securing IoT and sharing data in a secure and tamperproof way. The blockchain is a peer-to-peer connection system that performs transactions securely by using consensus algorithms with no need for a trusted third party.

The transition towards decentralized energy systems, driven by the global shift to renewable energy sources, introduces new cybersecurity complexities that challenge traditional energy security paradigms. Distributed Renewable Energy (DRE) systems comprising solar photovoltaics, wind turbines, microgrids, and battery storage are inherently decentralized, networked, and reliant on advanced digital technologies for real-time monitoring, control, and optimization. While these systems offer resilience, flexibility, and sustainability, they also expand the attack surface for cyber threats due to their reliance on Internet of Things (IoT) devices, cloud computing, and bidirectional communication protocols. This paper critically examines the cybersecurity challenges associated with DRE infrastructure, including unauthorized access, data breaches, malware propagation, and system manipulation, all of which could lead to energy theft, grid instability, and large-scale outages. Emerging opportunities lie in developing adaptive cybersecurity frameworks tailored to the unique topology of decentralized energy networks. These include the integration of artificial intelligence for anomaly detection, blockchain technologies for secure data exchange and identity management, and zero-trust architectures to enforce stringent access control. Additionally, the convergence of operational technology (OT) and information technology (IT) within DRE environments demands cross-sectoral collaboration, robust regulatory frameworks, and enhanced stakeholder awareness to build cyber-resilient systems. The paper also highlights the necessity for proactive risk assessment, real-time threat intelligence sharing, and the establishment of decentralized security standards to harmonize practices across diverse stakeholders and jurisdictions. Case studies from recent cyber incidents in the energy sector provide empirical evidence of vulnerabilities and mitigation strategies. By exploring both the risks and solutions, the study underscores the dual imperative of securing DRE systems not only as critical infrastructure but also as pivotal enablers of the global clean energy transition. In conclusion, while decentralized energy systems present new cybersecurity challenges, they also create opportunities to reimagine and strengthen energy security in the digital age. Addressing these issues through innovation, regulation, and cooperation will be crucial for ensuring sustainable and secure energy futures.
