Abstract

Multilevel database security is a security management which provides clearance levels for users. It also provides classification labels for the data. Most multilevel secure database systems employ the mandatory access control as proposed by Bell and La Padula. Most research works apply the multilevel secure technique to conventional relational databases. This research project proposes an extension to the mandatory access control so that it suits our application requirements. Moreover, the support of bitemporal database features is also included. Both valid time and transaction time are added to the already complex multilevel secure relational database. Integrity rules for this new model are introduced and finally, an extension to the SQL language is proposed to be used on the data model.
双时态多级安全数据库系统
多级数据库安全是一种为用户提供权限级别的安全管理。它还为数据提供分类标签。大多数多级安全数据库系统采用Bell和La Padula提出的强制访问控制。大多数研究工作将多层安全技术应用于传统的关系数据库。本研究项目提出了对强制访问控制的扩展,以满足我们的应用需求。此外,还包括对双时态数据库特性的支持。有效时间和事务时间都被添加到已经很复杂的多层安全关系数据库中。介绍了这种新模型的完整性规则,最后提出了在数据模型上使用SQL语言的扩展。
