Abstract
An information processing apparatus includes a rewrite request receiving unit configured to receive a rewrite request for rewriting an execution module, an update module determination unit configured to determine whether an update module that issues the rewrite request is an authorized module, a first falsification detection unit configured to detect falsification of a whitelist, an unauthorized-rewriting prevention unit configured to prevent unauthorized rewriting while maintaining a function of the information processing apparatus by rejecting the rewrite request without stopping the function of the information processing apparatus, in a case where the execution module for which the rewrite request is issued is registered in a whitelist for which the first falsification detection unit determines that no falsification is made and where the rewrite request is issued by an update module for which the update module determination unit determines to be an unauthorized update module.
