Abstract: | How to protect the database, the kernel resources of information warfare, is becoming more and more important since the rapid
development of computer and communication technology. As an application-level firewall, database security proxy can successfully
repulse attacks originated from outside the network, reduce to zerolevel damage from foreign DBMS products. We enhanced the
capability of the COAST's firewall reference model by adding a transmission unit modification function and an attribute value
mapping function, describes the schematic and semantic layer reference model, and finally forms a reference model for DBMS
security proxy which greatly helps in the design and implementation of database security proxies. This modeling process can
clearly separate the system functionality into three layers, define the possible security functions for each layer, and estimate
the computational cost for each layer.
