Information collection system, information collection method, medium, and information collection program

A computer-implemented information collection method comprising:

• deriving load information to estimate an impact on the availability of a target machine for active scanning by using side-channel data;
• generating an allow list including a scan timing and a scan range in which the availability is not affected, the allow list being based on the load information;
• and
• storing the allow list in memory,
• wherein an active scan of the target machine is executed by referencing the allow list stored in the memory to collect asset information of the target machine.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute:

• deriving load information to estimate an impact on the availability of a target machine for active scanning by using side-channel data;
• generating an allow list including a scan timing and a scan range in which the availability is not affected, the allow list being based on the load information;
• and
• storing the allow list in memory,
• wherein an active scan of the target machine is executed by referencing the allow list stored in the memory to collect asset information of the target machine.
