企业网络可信评估实验模型的设计研究

Enterprise Network Trusted Evaluating Experiment Model Design Research

企业的网络可信性评估是在国家相关法律和国际公约、标准[1]-[5]的相关规定范围内对企业的局域网进行网络可信性仿真环境下的评估实验测试。从实验方法学上对网络给出了一个从真实网络到仿真实验再到真实网络的网络分级的可信评估的具体模型和实现过程。网络建模过程采用抽取真实网络的网络数据[6],建立标准指纹特征库,建立仿真环境,产生发送离散随机测试协议数据包,按照测试模型构架处理、收集数据,根据可信评估的数学模型使用集合论的方法,用集合中的矩阵向量数据生成数据库并进行处理;在动态测试过程中采用了仿真环境下的破坏性崩溃测试方法。在真实网络上对结果数据进行抽样测试,验证模型建立的准确性和评估结果的可信性。

The enterprise network credibility appraisal is an assessment test in simulation environment for network credibility as specified in the international law, agreement and standard. A concrete assessment model and realization process was given which was graduated from real network to simulation network, and again returned to real network. The data was sampled from real network in the process of modeling, and standard fingerprint characteristic database, simulation environment was established, separate stochastic protocol data packs were produced and transmitted, and the data was processed and collected according to the structure of test model. According to the credible appraisal mathematical model, the set theory method was used, and the database was formed with set matrix vector data. In the dynamic test process, the destructive collapse test method was used under the simulation environment. Taking the sample from the real network, the model accuracy and assessment reliability were verified.
