Feature Subset Search for Cybersecurity in Industrial Internet of Things Environment Using Coot Optimization Algorithm
The Industrial Internet of Things (IIoT) is the incorporation of industrial processes with smart technology and interconnected devices to improve productivity and efficiency. The need for robust cybersecurity measures is crucial as the IIoT environment becomes vital to critical infrastructure in industries. Cybersecurity in IIoT is paramount to secure against possible threats, which ensures the integrity and resilience of industrial operations. Intrusion detection systems (IDSs) are instrumental in detecting anomalies, unauthorized access, or malicious activities. The incorporation of deep learning (DL) further reinforces the cybersecurity posture of the IIoT network. DL approach excels in analyzing complex and large datasets, which enables the detection of complex cyber threats by learning anomalies and patterns. Industrial processes can operate with heightened security, securing sensitive information, and critical infrastructure, and maintaining the reliability of a connected system in the industrial landscape by combining IIoT cybersecurity with innovative intrusion detection and DL technologies. Therefore, this article proposes an Integration of Coot Optimization Algorithm-based Feature Subset Search with Deep Learning for Cybersecurity (COAFSS-DLCS) technique on IIoT network. The objective is in the effectual recognition and classification of cyberattacks in the IIoT environment. Initially, the COAFSS-DLCS method uses min-max scalar to transform the input dataset into a suitable format. Furthermore, the COAFSS-DLCS employs the COAFSS approach for choosing an optimal feature subset. Additionally, the stacked long short-term memory autoencoder (SLSTM-AE) model is employed for classification. Moreover, the parameters of the SLSTM-AE classifier are fine-tuned using the Arithmetic Optimization Algorithm (AOA) for improved performance. A comprehensive empirical validation of the COAFSS-DLCS approach is performed under the UNSW_NB15 and UCI_SECOM datasets. The simulation outputs inferred the power of the COAFSS-DLCS over other methods.
