The increasing prevalence of unknown-type attacks on the Internet highlights importance developing efficient intrusion detection systems. While machine learning-based techniques can detect unknown types attacks, need for innovative approaches becomes evident, as traditional methods may not be sufficient. In this research, we propose a deep solution called log-cosh variational autoencoder (LVAE) to address challenge. LVAE inherits strong modeling abilities (VAE), enabling it understand...

A large amount of sensitive information is generated in today’s evolving network environment. Some hackers utilize low-frequency attacks to steal from users. This generates minority attack samples real traffic. As a result, the data distribution traffic asymmetric, with number normal and rare To address imbalance problem, intrusion detection systems mainly rely on machine-learning-based methods detect attacks. Although this approach can attacks, performance not satisfactory. solve...
