摘要
PROBLEM TO BE SOLVED: To provide an update information protection device for a program start-up setting file preventing careless rewriting or falsification of the setting file used at the start-up time of a program to secure safety of the setting file for the program important to system operation. SOLUTION: In this protection device, by registering the setting file 9 used at the start-up time of the program 10 to a disk as an image 6 and forbidding access to the disk except the start-up time of the program 10, the unjust rewriting to the image 6 that is the setting file 9 for the program start-up is prevented. When starting up the program 10, a program start-up confirmation means 4 decides the presence of the falsification of the image 6, and the program 10 is forbidden to read the image 6 as the setting file 9 when the falsification is present. Thereby, the start-up of the program 10 based on the unjust setting file is prevented.
