Abstract: The inner and external behaviors of software modules can be described with interface automata, and also the overall framework operating mechanism can be described according to component composition method of interface automata. Therefore, by using interface automata the challenges of supporting multi-DBMS protocol analysis of database activity monitoring tool based on network sniffer, distributed deployment and cooperative work of the tool can be solved. Interface automata models have been given, which contain the inner and external behavior models of the tool’s main modules and the tool overall behavior model. In the end, experiments have been performed to verify correctness and usability of the tool implemented based on the model.

Key words: database security, database activity monitoring, interface automata, protocol analysis
