Comparative Study of Deep Learning and Machine Learning in Intrusion Detection

Deep Learning for Intrusion Detection Systems

Overview of Deep Learning Models

The increasing volume of network traffic and sophisticated cyber threats necessitate the development of advanced Intrusion Detection Systems (IDS). Traditional IDS often struggle with high false positive rates, complex feature engineering, and class imbalances in datasets. To address these challenges, various deep learning models have been implemented, including multilayer perceptron (MLP), convolutional neural networks (CNN), and long short-term memory (LSTM) networks. Traditional algorithms such as logistic regression, naive Bayes, random forest, K-nearest neighbors, and decision trees are also analyzed.

Performance Comparison of Models

A significant contribution of the research is the application of the synthetic minority over-sampling technique (SMOTE) to handle class imbalances, enhancing the learning process. The models undergo extensive performance comparisons, which involve correlation-based feature selection and hyperparameter tuning to maximize detection accuracy. Results reveal that deep learning models, particularly CNN and LSTM, outperform traditional machine learning approaches in detecting cyber threats, achieving accuracy rates of 98%. Notably, random forest stands out with the highest accuracy at 99.9%.

Conclusion

For organizations seeking to enhance their cybersecurity measures, implementing advanced IDS using deep learning techniques offers a promising solution. The findings underscore the potential benefits of utilizing deep learning models tailored to specific network conditions.

Ransomware Attacks Target Russian Vodka and Healthcare Sectors

The Novabev Group, parent company of the Beluga vodka brand, experienced a ransomware attack on July 14, 2025, causing significant disruptions. The attack affected WineLab, the company's liquor store chain, leading to a three-day closure of over 2,000 locations in Russia. The company reported that the attack crippled its IT infrastructure, particularly point-of-sale systems and online services. Novabev Group stated, "The company maintains a principled position of rejecting any interaction with cybercriminals and refuses to fulfill their demands."

Preventing ClickFix Attacks: Safeguarding Against Human Error

ClickFix is an emerging social engineering technique utilized by threat actors to exploit human error. This technique involves misleading users into executing malicious commands under the guise of providing "quick fixes" for common computer issues. Threat actors use familiar platforms and deceptive prompts to encourage victims to paste and run harmful scripts.
