Research on Dynamic Network Security Defense Mechanism Based on Simulated Intrusion

Network security is facing evolving threats. In order to improve the intelligence and adaptability of network security defense, this study discusses a dynamic network security (DNS) defense mechanism based on simulated intrusion. Through the in-depth analysis of simulated intrusion data, this study constructs a threat behavior model and designs several attack scenarios to evaluate the performance of the mechanism in different environments. By using simulated intrusion data, a threat behavior model is established, which makes the dynamic defense mechanism better understand the possible threats in the network, which provides a more accurate basis for real-time detection. The experimental results show that in many experiments, the dynamic defense mechanism shows the improvement of attack detection rate, the decrease of false alarm rate and relatively stable response time. The improvement of attack detection rate reflects the adaptability of the mechanism to various attack types, while the decrease of false alarm rate shows that the mechanism has made remarkable progress in false alarm management. DNS defense mechanism based on simulated intrusion provides a new, flexible and efficient defense means for network security. This study provides a new idea and experimental basis for building a more intelligent and adaptable network security defense system.
