Intrusion detection and response of network node attacks based on game theory

Aiming at the problem that the traditional one-to-one correspondence method is cumbersome and lacks of effective correspondence when responding to the intrusion detection results after the detection of network node attacks, an intrusion detection and response structure based on game theory is proposed, and an intrusion detection and response model based on Markov game decision is established. Considering the system resources, response cost, detection rate, false positive rate and false negative rate, the response decision of intrusion detection system is simulated under the condition of considering the resource consumption and detection accuracy. The factors influencing the intrusion response decision are analyzed experimentally, which provides experimental basis for practical application.
