评估方法在网络安全评估过程的作用是非常大的。一个评估方法的好坏将会直接影响到评估结果的准确性。一般来说,安全评估方法的选择和组织的规模、信息系统的复杂程度、系统要达到的安全级别程度紧密相关。大多数学者一般将安全评估方法分为四大类:定性的评估方法、定量的评估方法、综合的评估方法、基于模型的评估方法。 Evaluation methods in the network security assessment process is very large. The quality of an assessment will have a direct impact on the accuracy of the assessment. In general, the selection of safety assessment methods is closely related to the size of the organization, the complexity of the information system, and the degree of safety to be achieved by the system. Most scholars generally divide safety assessment methods into four categories: qualitative assessment method, quantitative assessment method, comprehensive assessment method, and model-based assessment method.
