摘要
结合数据库的用户身份认证与自主访问控制研究,设计了LogicSQL多级安全模型。该模型把安全级分为分层密级和非分层的范围组成的二元组形式,主要从安全标签、强制访问控制和审计方面进行讨论。该模型在企业搜索与公安系统中得到应用。
A multilevel security mpdel of LogicSQL database, which is based on user identifier, discretionary access control（DAC） of database, is designed. Multilevel security model requires that all users and resources are classified and assigned a security label, which is a combination of a hierarchical security level and non - hierarchical security categories. Discussed a few aspects of LogicSQL multilevel security model ,including LogicSQL label, mandatory access control （MAC）, and audit. The model is applied in enterprise search and police system.
