Combining dynamic and static host intrusion detection features using variational long short-term memory recurrent autoencoder Объединение преимуществ динамического и статического обнаружения вторжений с использованием вариационного рекуррентного автокодировщика с долгой краткосрочной памятью

Despite the many advantages offered by Host Intrusion Detection Systems (HIDS), they are rarely adopted in mainstream cybersecurity strategies. Unlike Network Intrusion Detection Systems, a HIDS is the last layer of defence between potential attacks and the underlying OSs. One of the main reasons behind this is its poor capabilities to adequately protect against zero-day attacks. With the rising number of zero-day exploits and related attacks, this is an increasingly imperative requirement for a modern HIDS. In this paper variational long short-term memory — recurrent autoencoder approach which improves zero-day attack detection is proposed. We have practically implemented our model using TensorFlow and evaluated its performance using benchmark ADFA-LD and UNM datasets. We have also compared the results against those from notable publications in the area. © 2024 Saint Petersburg State University. All rights reserved.
