Enhancing cybersecurity in cloud computing and WSNs: A hybrid IDS approach

The evolution of cloud computing has revolutionized how users access services, simplifying the development and deployment of applications across various industries. With its pervasive adoption, robust security measures become imperative. Integrating Intrusion Detection Systems (IDSs) into cloud computing and Wireless Sensor Networks (WSNs) addresses these challenges. IDSs serve as attentive protectors, monitoring network traffic and responding to breaches promptly, enhancing security across industries reliant on cloud services. Similarly, IDS integration in WSNs ensures the security of mission-critical operations, despite resource constraints and dynamic topologies, facilitated by cloud computing. This research proposes a hybrid IDS approach, leveraging the NSL-KDD dataset and methodologies like Intrusion Support Scalar Impact Rate (ISSIR), Optimized Support Vector Machine (OSVM), Extended Long-Short-Term Memory (ELSTM), and Multilayer Perceptron Neural Network (MLPNN), enhancing intrusion detection efficacy. ISSIR aids in feature selection, OSVM mitigates localization errors, ELSTM enables precise anomaly detection, and MLPNN provides robust defense mechanisms. Each method is integrated into a collaborative framework to address specific challenges in detecting intrusions with higher accuracy and reduced false positives. The interplay between these methodologies strengthens the overall intrusion detection framework, addressing the dynamic nature of cybersecurity threats. Results demonstrate the superior performance of MLPNN across various metrics, showcasing its effectiveness in accurately predicting outcomes compared to other models. The proposed MLPNN hybrid system achieves an accuracy of 99.9%, surpassing state-of-the-art methods. This study underscores the significance of advancing IDSs in cloud computing and WSNs, offering insights into enhancing security and mitigating vulnerabilities in an interconnected digital landscape.
