Abstract: To aim to provide a monitoring system and a program execution apparatus that are capable of maintaining the security intensity even in the case where an unauthentic install module is invalidated. Install modules included in an apparatus each monitor an install module, which is a monitoring target indicated by a monitoring pattern included therein, as to whether the install module performs malicious operations. An install module that performs malicious operations is invalidated in accordance with an instruction from an update server. The monitoring patterns are restructured by the update server such that the install modules except the invalidated install module are each monitored by at least another one of the install modules. The restructured monitoring patterns are distributed to the install modules except the invalidated install module.

Abstract: A management device detects whether any normal monitoring module that has not been tampered with exists by referring to monitoring results received from an information security device and selects, when existence is detected, one of the monitoring modules and assumes that the selected monitoring module has been tampered with. The monitoring device then successively applies a procedure to monitoring modules other than the selected monitoring module by referring to the monitoring results, starting from the selected monitoring module, the procedure being to assume that any monitoring module determining that a monitoring module assumed to have been tampered with is normal has also been tampered with. As a result of the procedure, when all of the monitoring modules are assumed to have been tampered with the management device determines the selected monitoring module to be a normal monitoring module that has not been tampered with.
