Anomaly Detection through Adaptive DASO Optimization Techniques

Abstract

An intrusion detection systems (IDS) detect and prevent network attacks. Due to the complicated network environment, the ID system merges a high number of samples into a small number of normal samples, resulting in inadequate samples to identify and train and a maximum false detection rate. External malicious attacks damage conventional IDS, which affects network activity. Adaptive Dolphin Atom Search Optimization overcomes this. Thus, the work aims to create an adaptive optimization-based network intrusion detection system that modifies the classifier for accurate prediction. The model selects feature and detects intrusions. Mutual information selects feature for further processing in the feature selection module. Deep RNNs detect intrusions. The novel Adaptive Dolphin Atom Search Optimization technique trains the deep RNN. Adaptive DASO combines the DASO algorithm with adaptive concepts. The DASO is the integration of the dolphin echolocation (DE) with the atom search optimization (ASO). Thus, the intrusions are detected using the adaptive DASO-based deep RNN. The developed adaptive DASO approach attains better detection performance based on several parameters such as specificity, accuracy, and sensitivity.

Performance Improvement Scheme of NIDS Through Optimized Intrusion Pattern Database

“…The use of DASO Optimization Techniques was investigated by the author [14], which strongly emphasizes the value of a well-organized database for an anomaly detection system. In order to improve anomaly identification, the study uses adaptive DASO optimization approaches, demonstrating resilience to shifting network dynamics and leading to an increase in anomaly detection accuracy.…”
