Zusammenfassung:The objective of the present invention is to reliably execute countermeasure processing for a vulnerability prior to occurrence of an attack targeting the vulnerability. A vulnerability countermeasure processing unit (1233) performs countermeasure processing for vulnerability of a vulnerable library function, which is a general-purpose library function with vulnerability, among general-purpose library functions included in a general-purpose library (1230). A countermeasure selection unit (1232), if the vulnerable library function is requested to be called at execution time of a Web application (1220), causes the vulnerability countermeasure processing unit (1233) to perform the countermeasure processing for the vulnerability of the vulnerable library function, and subsequent to the countermeasure processing by the vulnerability countermeasure processing unit (1233), calls the vulnerable library function.
