Abstract: According to one embodiment, an electronic device includes a policy acquirer, a random number generator and a confirmation time determination processor. The policy acquirer acquires policy information indicating a common storage area storing an update program, and a time period in which presence or absence of the update program in the common storage area is to be confirmed. The random number generator generates a random number. The confirmation time determination processor creates a plurality of candidate times by dividing the time period by a predetermined time unit, and determines a confirmation time at which presence or absence of the update program is to be confirmed by selecting one of the plurality of candidate times using the random number.

Abstract: According to one embodiment, a system includes a first electronic apparatus and a second electronic apparatus. The first electronic apparatus causes an external storage medium to store first information which controls possibility of writing of a file to the external storage medium in units of file. The second electronic apparatus determines possibility of the writing of a requested file to the external storage medium based on the first information, write the requested file to the external storage medium if the requested file is determined to be capable of being written, and prohibit the writing of the requested file to the external storage medium if the requested file is determined to be incapable of being written.

Abstract: According to one embodiment, a setting method, includes storing, in a first partition of a storage which stores a first file causing a processor to execute a first program to booting an operating system, a second file having a same path as a path of the first file and causing the processor to execute a second program. The second program is executed by the processor at activation of an information processing apparatus and causing the processor to execute the first program.

Abstract: According to at least one embodiment, an electronic device includes a storage comprising a plurality of sectors and a processor configured to encrypt data in the plurality of sectors of the storage. The processor is configured to cause to be stored in a storage area address information indicating a defective sector from which data cannot be read, when the defective sector is detected during encryption.
