A software behavior modeling device which forms a model of a behavior of software includes; an event information acquisition unit configured to acquire event information indicating a specific event which occurs during execution of the software; a stack information acquisition unit configured to acquire stack information stored in a call stack at a time of occurrence of the specific event; a score setting unit configured to set a score in accordance with a storage location in which each element included in the stack information is stored in the call stack; and a model generating unit configured to form a model of a relationship between the specific event and the element by using the score, and to generate a behavior model of the software.
