A computer-readable recording medium recording a worm detection parameter setting program for setting an appropriate worm detection parameter for target environments. When a log reader loads a communication log created within a prescribed time period, a log classifier classifies the entries of the communication log into categories based on communication contents. A frequency distribution creator analyzes the entries of a category, counts the number of appearance of each worm detection parameter value for each object of a preset network unit, and creates frequency distribution information. A threshold derivation unit analyzes the frequency distribution information and derives a threshold value that is used for determining whether a worm is propagating. An output unit outputs to an output device the threshold value for the worm detection parameter for the category, together with the frequency distribution information created by the frequency distribution creator, thereby providing a user with the information.
