Research and application of dynamic audit policy for secure spatial database
安全空间数据库动态审计策略的研究与应用

A dynamic audit policy model based on secure spatial DBMS was proposed. The model could fully express audit policies based on time and space constraints, and monitor users' activities real-timely by using constraints mechanism. Furthermore, fine-grained audit policies could be expressed by introducing coherent properties expression. Then the algorithm was presented to trigger the rules. Finally, through embedding audit policy module, constraint policy module and log module, the dynamic audit policy model based on secure spatial DBMS Sec_Vista was realized.
