Abstract
With the increasingly complex network environment, intrusion detection systems are faced with severe challenges such as high-dimensional feature redundancy, category imbalance and low detection accuracy. Aiming at these problems, this paper proposes a multi-objective and multi-strategy collaborative optimization intrusion detection model (MCO-IDM). The model innovatively integrates multi-objective optimization techniques to simultaneously optimize conflicting objectives such as minimizing the number of features, maximizing detection accuracy and minimizing false alarm rates, and integrates collaborative search strategies such as dynamic adaptive mechanisms and swarm intelligence optimization algorithms (such as CMO-BOA) to achieve efficient trade-offs through Pareto frontier search and weight adjustment. The test results show that on globally public datasets such as KDD CUP99, NSL-KDD and CIC-IDS2017, MCO-IDM achieves the highest accuracy rate of 97.8%, the false alarm rate is reduced to 4.3%, and the training time is controlled within 185.3 seconds. At the same time, it maintains high robustness and scalability under different data scales. These results confirm the effectiveness of the model in feature selection, parameter optimization and multi-policy collaboration, and provide a new scheme with high precision and strong practicability for network intrusion detection.
