MANAGEMENT SYSTEM, ACQUISITION DEVICE, AND MANAGEMENT METHOD

1 . A management system comprising:

a management device configured to manage arranged file, a generation device configured to generate collation information to be collated by the management device when performing a tampering verification or an excess/deficiency verification of a file, and an acquisition device configured to acquire information to be used for generation of the collation information in the generation device,

wherein the acquisition device includes

first processing circuitry configured to:

acquire, from a device configured to store shared common definition information indicating a definition of a common list serving as a list of files and directories likely to be described in the collation information and a definition of an element attribute serving as conditions for determining elements of a list of files and directories in the collation information in an individual file management device, first common definition information corresponding to identification information of the first common definition information input to the acquisition device;

compare the first common definition information acquired by the first acquisition unit with the file managed by the file management device to distinguish whether there is a file satisfying all the conditions of the first common definition information; and

output, to the generation device, second common definition information corresponding to the file managed by the file management device among the first common definition information acquired based on a distinction result.

2 . The management system according to claim 1 , wherein the first processing circuitry is further configured to acquire another identification information relevant to the identification information of the first common definition information input to the acquisition device, and acquire the second common definition information based on the identification information of the first common definition information input to the acquisition device and the other identification information.

3 . The management system according to claim 1 ,

wherein the generation device includes

second processing circuitry configured to:

acquire at least a part of the second common definition information output by the acquisition device, and

generate collation information having a first list, as the collation information, indicating a combination of a file path of a file to be arranged and of which file data does not change and a digest value of the file data, a second list indicating a file path of a file to be arranged and of which file data is changeable, and a third list indicating a directory path of directory satisfying a first directory condition indicating a directory in which a file arranged directly under is a file described in the first list or the second list belonging to an identical collation information, a second directory condition indicating a directory in which a directory arranged directly under is a directory under which one or more files described in the first list or the second list belonging to an identical collation information are arranged, and a third directory condition indicating a directory that a file or a directory not corresponding to the first directory condition or the second directory condition is not arranged directly under, based on a common list and an element attribute of the second common definition information acquired.

4 . The management system according to claim 3 , wherein the second processing circuitry is further configured to set a value to be set as individual definition information according to a state of files present in the file management device, the individual definition information being information indicating a condition to be individually provided according to the file management device, for a file to be arranged in the file management device.

5 . An acquisition device for acquiring information to be used for generation of collation information to be collated when a tampering verification or an excess/deficiency verification of a file is performed, the acquisition device comprising:

processing circuitry configured to:

acquire, from a device configured to store shared common definition information indicating a definition of a common list serving as a list of files and directories likely to be described in the collation information and a definition of an element attribute serving as conditions for determining elements of a list of files and directories in the collation information in an individual file management device, first common definition information corresponding to identification information of the first common definition information input to the acquisition device;

compare the first common definition information acquired with a file managed by the file management device to distinguish whether there is a file satisfying all the conditions of the first common definition information; and

output second common definition information corresponding to a file serving as a management target among the first common definition information acquired based on a distinction result.

6 . A management method executed by a management system including a management device configured to manage arranged file, a generation device configured to generate collation information to be collated by the management device when performing a tampering verification or an excess/deficiency verification of the files, and an acquisition device configured to acquire information to be used for generation of the collation information in the generation device, the management method comprising:

acquiring, by the acquisition device, from a device configured to store shared common definition information indicating a definition of a common list serving as a list of files and directories likely to be described in the collation information and a definition of an element attribute serving as conditions for determining elements of a list of files and directories in the collation information in an individual file management device, first common definition information corresponding to identification information of the first common definition information input to the acquisition device;

comparing, by the acquisition device, the first common definition information that is acquired with the file managed by the file management device to distinguish whether there is a file satisfying all the conditions of the first common definition information; and

outputting, by the acquisition device, to the generation device, second common definition information corresponding to the file managed by the file management device among the first common definition information acquired based on a distinction result.
