摘　　要：资产识别是网络安全动态风险评估过程的首要环节,在基于层面的信息资产划分方法上,通过数据挖掘技术中的决策树算法,研究了信息资产识别问题。实现了数据挖掘技术在资产识别中的应用。在对C4.5算法的基本流程进行描述的基础上,以信息资产数据集中的操作系统为例,利用C4.5算法实现了对数据的正确分类,并进行了规则的提取,为以后进行资产识别提供了依据,并指明了今后该算法在信息资产识别其他方面的研究方向。The information property recognition is a primary link of information security risk assessment process. On the basis of level-based information property recognition method, the identification problem of information assets is studied through decision tree arithmetic of data mining technology. The application of data mining in identification of information assets is realized. Based on describing the basic process of C4.5 arithmetic and taking the operating system of information property as an example, the data is classsified by CA. 5 arithmetic and the rules are extracted for providing basis of information property recognition. Finally, the algorithm＇s research directions in other aspects of information property recognition is pointed out.
