Abstract: For a variety existing vulnerability assessments problems in the complex network system, such as the inaccurate vulnerability assessment quantization, the large assessment error, etc, this paper designs a quantitative vulnerability assessment method, which takes adjacency matrix knowledge as theoretical basis and combines the complex network systems environment. This method starts detailed in-depth discussion from the level of professional intruder singly on the one hand; on the other hand, it also introduces the intruders’ choosing ability and the size of intruders’ selecting invasion network node ability; in addition, it also designs the information structure of the network sub-station to verify the effectiveness of this method. The validation results indicate that this method of vulnerability research network system has great advantage.
