DATA FLOW ANALZYING APPARATUS, DATA FLOW ANALYZING METHOD AND DATA FLOW ANALYZING PROGRAM

A data flow analyzing apparatus includes an analysis rule storage which stores analysis rules having definitions of data types, a data flow analyzer which performs data flow analysis on an analysis target program as a target of analysis by using the analysis rules stored in the analysis rule storage to thereby output unsafe data-including procedures as detected points, an analysis rule candidate generator which generates candidates of analysis rules based on the detected points, and an analysis rule candidate output which outputs the analysis rule candidates generated by the analysis rule candidate generator to a predetermined output.
