Abstract

Cyber-attack detection is crucial for safeguarding sensitive data, digital assets, and critical infrastructure. This research introduces the "Peak Synergy Network Model Framework (PSNM)", a revolutionary method that improves detection accuracy, resilience, and adaptability to evolving threats by utilizing Multi-Agent Reinforcement Learning (MARL). Conventional MARL techniques face several drawbacks, including high computational demands, the need for large volumes of data, and challenges in agent coordination. The proposed framework addresses these issues by incorporating several innovative components. First, comprehensive data preprocessing ensures high-quality training inputs through cleaning and normalization. The intrusion response system is modelled as a multi-attribute decision-making problem, optimizing time efficiency, cost, and resource constraints. The proposed "Antecedent DQN Model" maximizes the predicted cumulative discounted reward and ensures convergence to an optimal policy by employing Markov Decision Process parameters. A key advancement is the "Shared Decision-Making Protocol," which enables agents to independently learn policies through local observations, resulting in faster and more reliable convergence with minimized communication overhead. Furthermore, "Premium Hyperparameter Optimization" fine-tunes each parameter’s learning rate, accelerating training and enhancing overall performance. The effectiveness of the proposed framework has been validated through performance metrics, achieving 99.9% accuracy, 100% precision, 99.9% recall, 99.9% F1-score, and a 0.0 false positive rate. These results confirm the framework’s substantial potential for effectively detecting advanced and dynamic cyber threats.
