ML enables systems to learn from data without explicit programming, enhancing their capacity to detect cyber threats through experience. Various ML models have been applied to cybersecurity, categorized into supervised, unsupervised, semi-supervised, and reinforcement learning.

Deep Learning (DL)

DL, a subset of ML, processes large datasets through neural networks, facilitating the automatic detection of cyber threats while adapting to evolving attack methods. DL architectures, such as Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) networks, are increasingly utilized due to their effectiveness in pattern recognition relevant to cybersecurity tasks.

Metaheuristic Algorithms

Metaheuristic algorithms optimize processes within complex and dynamic environments, making them ideal for feature selection in cyber-attack detection. Their classification includes evolution-based, swarm intelligence-based, and human-related algorithms, each employing different strategies to optimize detection efficiencies.
