Abstract: This paper analyzes the attack effect of target network and the ability of attackers, basing on Grey theory, it evaluates the ability of attackers in the process of network attacks. It gives the evaluation index system, and calculates the evaluation criterions. Experimental results in the actual network show that the method can quantitatively evaluates the ability of attacker in the process of network attacks.

Key words: attack effect, attack ability, information access, grey theory

摘要： 分析网络攻击对目标网络的破坏效果以及攻击者的攻击能力。基于灰色理论，提出一种评估攻击者攻击能力的方法，给出评估的指标体系，对评估准则进行计算。在实际网络中进行攻击实验，结果表明，该评估方法能有效对网络攻击过程中攻击者的攻击能力进行定量评估。
