Abstract
A malicious-module identification device identifies and deactivates a malicious module operating in an information processing device connected thereto via a network. The malicious-module identification device is provided with a reception unit for receiving results of tampering detection from a plurality of modules for detecting tampering, and a determination unit for assuming that a module among the plurality of modules is a normal module, determining, based on the assumption, whether a contradiction occurs in the received results of tampering detection and identifying the module assumed to be a normal module as a malicious module when determining that a contradiction occurs. A deactivation unit outputs an instruction to deactivate the module identified as the malicious module.
