The Internet of Medical Things (IoMT) introduces complex security challenges as interconnected medical devices enlarge the attack surface and limit the effectiveness of traditional intrusion detection systems (IDS). In this paper, we propose a Neuro-Symbolic Intent-Based Intrusion Detection System (NS-IBN) that integrates deep learning–based pattern recognition with symbolic reasoning to produce interpretable, intent-aligned security decisions. NS-IBN comprises an Intent-to-Symbol Translation Layer, an Intent-Driven Attention Mechanism, a Neural-Symbolic Synchronization Module, and a Symbolic Reasoning Engine that together link administrator-defined security intents to concrete detection behavior. In a representative intensive care unit (ICU) scenario with networked infusion pumps and vital-sign monitors, NS-IBN can be configured to detect lateral movement and unauthorized command injection while limiting disruptive false alarms for clinicians. Evaluation on the IoT-IDS2021 benchmark shows that NS-IBN achieves 98.3% accuracy, an explainability score of 0.94, and a 1.2% false positive rate, providing transparent and auditable intrusion detection for IoMT environments.

Sequential recommendation is becoming more critical in a variety of e-commerce platforms. The aim of sequential recommender systems is to model the dynamic preferences of users based on their previous actions and predict what they will do next. The collected user activity logs on real-world platforms could be quite long. This wealth of information provides options to follow users’ actual interests. Prior efforts primarily aimed at providing recommendations following recent behaviors. Meanwhile, the entire sequential data may not be used efficiently since early actions may influence users’ decisions at present. Furthermore, scanning the whole behavior sequence while doing inference for every user is unbearable due to the need for prompt reaction time in real-world applications. To this end, we propose the DELIGHT Sequential Recommender System (DSRS), which takes the above properties into account to recommend the next item the user might be interested in. DSRS divides the entire user behavior sequence into long- and short-term segments and models them through independent networks before integrating their learned representations. In particular, the first network learns user long-term, whereas the second one learns short-term preferences and then combines them for an efficient joint recommendation. Experimental findings across four datasets show that our model outperforms other state-of-the-art sequential models in apprehending long-term dependence.

In today’s world, fake news on social media is a universal trend and has severe consequences. There has been a wide variety of countermeasures developed to offset the effect and propagation of Fake News. The most common are linguistic-based techniques, which mostly use deep learning (DL) and natural language processing (NLP). Even government-sponsored organizations spread fake news as a cyberwar strategy. In literature, computational-based detection of fake news has been investigated to minimize it. The initial results of these studies are good but not significant. However, we argue that the explainability of such detection, particularly why a certain news item is detected as fake, is a vital missing element of the studies. In real-world settings, the explainability of the system’s decisions is just as important as its accuracy. This article explores explainable fake news detection and proposes a sentence-comment-based co-attention sub-network model. The proposed model uses user comments and news contents to mutually apprehend top-$k$explainable check-worthy user comments and sentences for detecting fake news. The experimental result on real-world datasets shows that our proposed model outperforms state-of-the-art techniques by 5.56% in the$F$1 score. In addition, our model outperforms other baselines by 16.4% in normalized cumulative gain (NDCG) and 22.1% in Precision in identifying top-$k$comments from users, which indicates why a news article can be fake.

A fundamental expectation of the stakeholders from the Industrial Internet of Things (IIoT) is its trustworthiness and sustainability to avoid the loss of human lives in performing a critical task. A trustworthy IIoT-enabled network encompasses fundamental security characteristics such as trust, privacy, security, reliability, resilience and safety. The traditional security mechanisms and procedures are insufficient to protect these networks owing to protocol differences, limited update options, and older adaptations of the security mechanisms. As a result, these networks require novel approaches to increase trust-level and enhance security and privacy mechanisms. Therefore, in this paper, we propose a novel approach to improve the trustworthiness of IIoT-enabled networks. We propose an accurate and reliable supervisory control and data acquisition (SCADA) network-based cyberattack detection in these networks. The proposed scheme combines the deep learning-based Pyramidal Recurrent Units (PRU) and Decision Tree (DT) with SCADA-based IIoT networks. We also use an ensemble-learning method to detect cyberattacks in SCADA-based IIoT networks. The non-linear learning ability of PRU and the ensemble DT address the sensitivity of irrelevant features, allowing high detection rates. The proposed scheme is evaluated on fifteen datasets generated from SCADA-based networks. The experimental results show that the proposed scheme outperforms traditional methods and machine learning-based detection approaches. The proposed scheme improves the security and associated measure of trustworthiness in IIoT-enabled networks.

The Internet of Medical Things (IoMT) effectively tackles several shortcomings of conventional healthcare systems. It includes medical personnel shortages, patient care quality, insufficient medical supplies, and healthcare expenditures. There are several advantages of using IoMT technology for enhanced treatment efficiency and quality, thus improving patient health. However, the frequency and magnitude of cyberattacks on IoMT are increasing at a breakneck pace. Therefore, this article proposes a cyberattack detection method for IoMT-based networks using ensemble learning and fog-cloud architecture to address security issues. The ensemble technique employs a set of long short-term memory (LSTM) networks as individual learners at the first level and stacks a decision tree on top of them to classify attack and normal events. In addition, we present a framework for deploying the proposed IoMT-based approach as Infrastructure as a Service in the cloud and Software as a Service in the fog. The proposed method is evaluated on the telemetry datasets of IoT and IIoT sensors (ToN-IoT) dataset, and the outcomes reveal that it surpasses the baseline approaches in terms of precision by 4%.
