Cloud Security Leveraging AI: A Fusion-Based AISOC for Malware and Log Behaviour Detection

Cloud Security Operations Center (SOC) enable cloud governance, risk and compliance by providing insights visibility and control. Cloud SOC triages high-volume, heterogeneous telemetry from elastic, short-lived resources while staying within tight budgets. In this research, we implement an AI-Augmented Security Operations Center (AISOC) on AWS that combines cloud-native instrumentation with ML-based detection. The architecture uses three Amazon EC2 instances: Attacker, Defender, and Monitoring. We simulate a reverse-shell intrusion with Metasploit, and Filebeat forwards Defender logs to an Elasticsearch and Kibana stack for analysis. We train two classifiers, a malware detector built on a public dataset and a log-anomaly detector trained on synthetically augmented logs that include adversarial variants. We calibrate and fuse the scores to produce multi-modal threat intelligence and triage activity into NORMAL, SUSPICIOUS, and HIGH\_CONFIDENCE\_ATTACK. On held-out tests the fusion achieves strong macro-F1 (up to 1.00) under controlled conditions, though performance will vary in noisier and more diverse environments. These results indicate that simple, calibrated fusion can enhance cloud SOC capabilities in constrained, cost-sensitive setups.

Time Series Anomaly Detection with CNN for Environmental Sensors in Healthcare-IoT

This research develops a new method to detect anomalies in time series data using Convolutional Neural Networks (CNNs) in healthcare-IoT. The proposed method creates a Distributed Denial of Service (DDoS) attack using an IoT network simulator, Cooja, which emulates environmental sensors such as temperature and humidity. CNNs detect anomalies in time series data, resulting in a 92\% accuracy in identifying possible attacks.

Machine Learning for Healthcare-IoT Security: A Review and Risk Mitigation

The Healthcare Internet-of-Things (H-IoT), commonly known as Digital Healthcare, is a data-driven infrastructure that highly relies on smart sensing devices (i.e., blood pressure monitors, temperature sensors, etc.) for faster response time, treatments, and diagnosis. However, with the evolving cyber threat landscape, IoT devices have become more vulnerable to the broader risk surface (e.g., risks associated with generative AI, 5G-IoT, etc.), which, if exploited, may lead to data breaches, unauthorized access, and lack of command and control and potential harm. This paper reviews the fundamentals of healthcare IoT, its privacy, and data security challenges associated with machine learning and H-IoT devices. The paper further emphasizes the importance of monitoring healthcare IoT layers such as perception, network, cloud, and application. Detecting and responding to anomalies involves various cyber-attacks and protocols such as Wi-Fi 6, Narrowband Internet of Things (NB-IoT), Bluetooth, ZigBee, LoRa, and 5G New Radio (5G NR). A robust authentication mechanism based on machine learning and deep learning techniques is required to protect and mitigate H-IoT devices from increasing cybersecurity vulnerabilities. Hence, in this review paper, security and privacy challenges and risk mitigation strategies for building resilience in H-IoT are explored and reported.
