摘要:

摘要:针对网络安全态势预测动态、实时等特性,设计了基于隐马尔可夫模型网络安全态势预测模型。根据t时刻的网络安全态势计算出t+1时刻的态势,同时结合最大熵算法,对态势进行一致性判定,提高了预测准确率。分析及模拟实验表明该基于隐马尔可夫模型的网络安全态势预测方法具有自主学习及主动防御特征,同时平衡了速度和准确度要求,能够高效、准确地进行网络安全态势预测。

Abstract:

Aiming at the dynamic and real-time characteristics of network security situation prediction,a network security situation prediction model based on hidden Markov model(HMM)was designed.According to the HMM,the situation in t+1 from t time can be calculated.Meanwhile,the maximum entropy algorithm was combinated with HMM to improve the accuracy rate.The analysis and simulation experiments show that the method has the characteristics of autonomous learning and active defense,and it also balance the speed and accuracy.

Key words: network security situation prediction, hidden Markov model, regularization, network security
