Abstract This paper proposes a quantization evaluation algorithm for attack graph based on node score named NSBRank, which is used to quantize the importance of all nodes in the attack graphs. It computes the initial ranks of all nodes, and works out the final ranks on the basis of the initial values, so that the relative importance between nodes is more clear, and the ability of response for network security is enhanced. Experimental results prove that NSBRank is more reasonable and effective.
