为提高攻击预警的准确性,本文在基于攻击意图的攻击预警方法的基础上提出了一种基于模糊聚类的攻击预警方法。该方法通过聚类攻击行为,量化和反映攻击者的攻击意图,从而对攻击者的下一步攻击行为进行准确预警。实验表明,该方法能够在有效的时间内更加准确地预测并报警攻击者下一步攻击行为,满足攻击预警时效性和准确性要求。 In order to improve the accuracy of attack early warning, this paper proposes an attack early warning method based on fuzzy clustering based on the attack early warning method based on attack intent. By clustering attack behavior, this method quantifies and reflects attackers’ attack intentions, so as to accurately warn attacker’s next attack. Experiments show that this method can predict and alert attackers more accurately in the effective time and attack attackers to meet the requirements of timeliness and accuracy.
