An object of this invention is to obtain a whitelist generator with which the accuracy of data relating to the specifications of normal communication serving as an automatic generation source can be guaranteed, whereby the accuracy of a generated whitelist can be guaranteed over an entire whitelist generation flow. The whitelist generator is applied to a system formed from a plurality of devices, the plurality of devices being configured to exchange data with each other, in order to generate a whitelist used for whitelisting intrusion detection, and includes a model verification unit that verifies, on the basis of an input model, at least one of whether or not normal communication in the system has been modeled correctly and whether or not the model is logically consistent, and a model conversion unit that converts the verified model into a whitelist.

First and second types of object detectors, a sensing device, and a mobile apparatus. The first and second types of object detectors include a light source configured to emit light, photoreceptor configured to receive the light reflected by an object, and a binarizing circuit configured to binarize a signal sent from the photoreceptor at a threshold V. In the first and second types of object detectors, object detection processes are performed in a same direction until a high-level signal is output M times from the signal binarized by the binarizing circuit. In the first type of object detector, a value of the M is determined based on an incidence of shot noise where peak intensity exceeds the threshold Vin the photoreceptor. In the second type of object detector, a threshold Vis set based on a value of the M.

A branch element identification unit identifies a branch element being a program element for branching, from a model diagram representing a plurality of program elements and a relationship among the program elements. A group identification unit identifies a branch destination group, the branch destination group being a series of program elements constituting branch destination of the branch element, for each branch destination from the model diagram. A sequence determination unit determines a sequence of the branch destination groups in a program code. A code generation unit generates the program code based on the model diagram. The program code includes codes corresponding to the branch destination groups in accordance with the sequence of the branch destination groups.

Execute a countermeasure process for vulnerability reliably before an attack aiming at vulnerability occurs. A vulnerability countermeasure processing unit performs a countermeasure process for vulnerability of a vulnerable library function being a general-purpose library function that has vulnerability among the general-purpose library functions included in a general-purpose library. A countermeasure selection unit, when a call for the vulnerable library function is requested at execution of a Web application, makes the vulnerability countermeasure processing unit perform the countermeasure process for the vulnerability of the vulnerable library function, and after the countermeasure process is performed by the vulnerability countermeasure processing unit, calls the vulnerable library function.
