Abstract

With the rise of remote work and the digital industry, advanced cyberattacks have become more diverse and complex in terms of attack types and characteristics, rendering them difficult to detect with conventional intrusion detection methods. Signature-based intrusion detection methods can be used to detect attacks; however, they cannot detect new malware. Endpoint detection and response (EDR) tools are attracting attention as a means of detecting attacks on endpoints in real-time to overcome the limitations of signature-based intrusion detection techniques. However, EDR tools are restricted by the continuous generation of unnecessary logs, resulting in poor detection performance and memory efficiency. Machine learning-based intrusion detection techniques for responding to advanced cyberattacks are memory intensive, using numerous features; they lack optimal feature selection for each attack type. To overcome these limitations, this study proposes a memory-efficient intrusion detection approach incorporating multi-binary classifiers using optimal feature selection. The proposed model detects multiple types of malicious attacks using parallel binary classifiers with optimal features for each attack type. The experimental results showed a 2.95% accuracy improvement and an 88.05% memory reduction using only six features compared to a model with 18 features. Furthermore, compared to a conventional multi-classification model with simple feature selection based on permutation importance, the accuracy improved by 11.67% and the memory usage decreased by 44.87%. The proposed scheme demonstrates that effective intrusion detection is achievable with minimal features, making it suitable for memory-limited mobile and Internet of Things devices.
