| 摘要: |
| 针对灰色关联分析算法无法定量评估样本、没有充分考虑到待评估指标间的关联性和决策者的期望问题，提出了一种基于改进的CRITIC(Criteria Importance Through Intercriteria Correlation)的灰色关联网络安全态势评估算法，借助于改进CRITIC的主客观赋权与TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)的思想来客观衡量当前的网络安全态势。在公开数据集与实际应用中的充分对比试验证明了所提方法的有效性与实用性。 |

| Abstract: |
| For the problem that the Grey Relational Analysis algorithm is unable to evaluate the samples quantitatively and the correlation between the indicators to be evaluated and the expectations of decision-makers have not been fully considered，a gray correlation network security situation assessment algorithm based on the improved Criteria Importance Through Intercriteria Correlation(CRITIC) is proposed.The current network security situation is objectively measured with the help of subjective and objective analysis of the improved CRITIC and the idea of Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS).Comparison tests between open data sets and practical application prove the practicability and effectiveness of the proposed method. |
